The Earth And Its Effects
by Henri Larvaron
Former Professor of Agricultural Chemistry
at Rennes University
Phenomena connected with life and vitality seem to owe their
nature to three types of radiation, according to the observations
of the Chinese over a millenium or more and to the conclusions of
contemporary biologists. These radiations are: the cosmic
radiations (Chinese "Yang"), telluric or earth radiations ("Yin"),
and thirdly, radiations specific to the chemical components of the
As a part of biology the existence of "harmful" rays -- affecting
the health of organic cells -- can be shown by locally weaker
plant growth. Among plants which can be used for the purpose
because they are particularly sensitive to those radiations are
lilac, currant bushes, apple trees, pines, leaf-artichike plants,
celery, begonias, hydrangeas, dahlias, nasturniums, rose-bushes,
box hedges, oaks, and hawthornes. These Harmful Radiations affect
large animals no less than insects: cats are attracted, birds
avoid them, ants make nests where the radiations pass. In other
countries than France and in numerous experiments rabbits and mice
have been made, for observation, to live in places where there are
these radiations to affect them.
Many Origins of "Harmful Rays"
A number of observers have written upon this subject. The origin
of "harmful rays" may be any of the following: dry or damp
geological faults, underground streams producing above them a
force possessing a dominant polarity, drains, cemeteries, all
subterranean cavities, electric wires, electric motors' fields,
petrol motors, special geological strata like felspath, also clay
or deposits of dead organic matter; the fact of two Earth Rays
crossing at a point ( the Partition Rays of Dr Peyre of Paris),
the effect of inductive coiled wires (solenoids); even the
"magnetic" properties (fluid) of certain people -- particularly of
those who are disease "carriers" or else produce alpha radiations
in excess; certain geometrical figures, as drawings or actual
objects. The length of this list of causes shows that the subject
is a vast one awaiting fuller research by biologists and
A certain German physicist is of the opinion that these radiations
lie between the hertzian band and the infrared band of
frequencies, with wavelengths between 0.345 cm and 10 cm. The
Radio-Campometre (our own radiesthetic appliance) reveals these
radiations with a length of between 8 mm and 4.5 cm (which may be
the recordings of harmonics).
The harmful nature of such radiations appears to be due to two
(1) Maximum ionization of the soil where irradiation is directed.
(2) The predominating polarity given to any living organism in the
field of influences derived from the radiation.
The intensity increases after dark, and is greatest on the day of
the full moon, on the day preceding it, and on the day which
follows. The intensity is also increased during magnetic storms
and seismic disturbances.
Our personal hypothesis is that cosmic and telluric radiations, as
the two main sources of General Energy, produce and maintain the
phenomenon of life in all living organisms, whether of the animal
or the plant kingdoms.
A simple experiment can illustrate the outstanding importance of
these two sources of energy: Take three equal-sized begonias in
their pots, numbered 1 to 3. No.1 will be protected from Telluric
Rays by an insulator -- (A perfect insulator cannot be found, as
oscillograph recordings show). No. 2 will be protected from Cosmic
Rays by means of a Faraday cage. No. 3 will remain untreated, as
the control plant.
It will be observed that Nos. 1 and 2 will wither or die, while
No. 3 continues to live normally. In other words, a combined
stimulation from cosmic and telluric radiations is essential for
life to be maintained.
To the above concept of the complementary action of these two
sources of energy, we add another hypothesis: "Every living
organism of its own accord absorbs a definite quantity of one or
other of these two sources of energy, as required, in order to
insure the vital function."
Let it not be forgotten that the living organism receives and also
itself emits radiation. As Dr Jules Regnault, now of Granville,
has written, "The living organism must be considered as an actual
oscillator and resonator."
The most disturbing fact which our own observations have shown in
the course of investigations is the following: in the case of
healthy living organism (plants or animals), the proportion of the
two sources of energy seems to be fixed, namely, cosmic radiation
100 units to telluric radiation 50 units; and whenever this
proportion is not maintained in an organism, one always finds it
ill or revealing some kind of deficiency. The constancy of these
proportions is a proof of Dame Nature's constancy.
Causes of Imbalance in Cellular Oscillation
We can quote from our observations the following causes of
(a) Excess "polar" radiation emitted by subterranean streams,
which have a predominating polarity;
(b) Radioactive emanations of certain soils which exhibit an
excess of alpha particles and gamma radiation, but a deficiency of
beta particles (an exception is to be made with regard to the
"rare earths", which emit a form of radioactive energy favorable
to plant life).
(c) Cosmic radiations in excess when they reach a soil deficient
In view of the numerous forms of radiation present in nature it
can easily be accepted that many of these radiations can bring
about a wave interference producing imbalance in many of the vital
radiations absorbed by living organisms. The latter are affected
when they are reached by the passing of these radiations; after a
certain length of time the ionic equilibrium of the living
organisms is thereby destroyed.
These observations, derived from numerous experiments, have led us
to evolve three solutions:
2. The broadcasting of selected vital forces for restoring
3. A combined arrangement with neutralization and a simultaneous
broadcasting of vital forces.
Before giving any description of the methods employed for solving
problem in each of the three ways, a few words may be said about
the phenomenon of radiations connected with the vital force. Let
these be called the "Vital Radiation", and let us see what is
meant by this. Earlier in this paper they were described as
apparently dependent upon the action of two forces, cosmic
radiation and telluric radiation. (For the time being influences
due to a specific soil's radiations will not be discussed, this
being reserved for a separate discussion).
The kind of experiment which can be repeated by anybody to prove
the action of these two types of energy has already been
described. In order to obtain a standard reaction or recording for
all radiesthetists we have constructed a pendulum specifically for
the assessment of this vital radiation. Both with the
"Radio-Capteur" constructed by Dr Regnault, and with our
"Radio-Campometre" we have been able to observe that corresponding
fields of influence are constant for the two following: cosmic
radiation received when the sky is blue and free from clouds;
telluric radiation, i.e., standard influences emanating from the
Constant recordings have been obtained for these, we have invented
three specific pendulums, namely the R.C. (Rayon Cosmique); the
R.T. (Rayon Tellurique); the R.V. (Rayon Vital), suitable for
standardizing radiesthetists' records.
As experiment will show, the pendulum R.V. provides gyrations only
over living organisms, and the gyration is in reverse rotation
whenever a field detected is due to any radiation unfavorable to
phenomena of vitality. This pendulum can thus indicate the degree
of the vital field's value. A study of this vital field,
supplemented by examination of the fields of cosmic and telluric
radiations, then shows the cause of any cell deficiency when there
is imbalance and there is no longer the normal standard proportion
between cosmic radiation and telluric radiation.
With these pendulums we can conduct biological examinations
according to what is required, the task being to determine one of
the three "causes of cellular oscillation imbalance". It is now
the moment for reporting on --
The Three Solutions :
No. 1 : Solutions -- It should be said that our
investigations stated in 1929. At this time a little neutralizer
had been invented for controlling the position of the vertical
over underground mines or sources of water. Dr Joly, of Paris,
happened to ask Dr Jules Regnault whether this appliance could be
effective for neutralizing areas above any soil emitting radiation
found harmful to health. During the six months of experimental to
observe the protective effects. (There can be no auto-suggestion
responsible for results obtained on plants). In view of what was
learned by this means an appliance was installed in the house of
Dr Joly's patient. At the end of several months the patient
congratulated us on its efficacy as shown by his restored health.
Since then this appliance has had improvements made to it, and
these can be outlined as follows:
1. -- Ability to collect the harmful radiation from the area where
it was detected;
2. -- Conveyance of this radiation to a neutralizing appliance, by
means of the radiation-conducting qualities of an insulated
3. -- Filtration of such harmful rays and conversion of their
wave-form to make the radiation favorable to living organisms.
Harmful radiation of this kind has been identified in human
habitations and in buildings used by horses, cows and pigs. At the
request of the owners our system of neutralization has been
installed. The following are two of the many letters of
appreciation received from farmers of the region (here translated
St. Neen, 22.9.47
Following your installation in my cow-sheds and my sties I have
observed that there have no longer been deaths as there were
before. The neutralization has been successful for about a year.
The stock great energy.
I am writing to tell you the result of installing neutralizers at
the beginning of June 1947. We now have 15 young pigs from two
sows, a thing which we never obtained before.
A sheaf of testimonials is available. Their reproduction in this
short paper would not be suitable.
It is to be noted that this neutralizer involves no expenditure on
upkeep. The energy it provides is derived from earth radiation
throgh being connected to the earth where the harmful earth rays
have been radiesthetically detected. The appliance does not have
any healing power in itself, but it brings about good health by
insuring that the living organisms are in a place favorable to the
development of the phenomena responsible for life, as research
undertaken since 1930 has proved.
Solution No. 2 : Emission of Vitalizing Radiations -- The
work on the frequencies of cells by Prof. Ch. Henry, of the
Sorbonne, need not be described again: nor need details be given
of Lakhovsky's view on the effect of oscillators on plants, of
similar work by the American, Dr McManus, and of work by the
Russian, Prof. Chiyevski. All these have closely examined the
biological question, the effect of radiations upon living
organisms, and, in in particular, upon plants.
On the same lines we have in turn studied the effects of
oscillators and the irradiation of different wavelengths. Without
entering into the details we can declare: "According to the extent
and to the intensity of the electromagnetic wavefield produced by
an oscillator and according to the degree of resonance of the
radiations upon living an oscillator and according to the degree
of resonance of the radiations to the living organisms, the effect
is either favorable or unfavorable to the phenomena of life."
After numerous tests we have for the same purpose succeeded in
inventing two methods:
The First Method Irradiation, based on use of a
hertzian-wave transmitter capable of providing the two types of
vital radiations. With this appliance we have irradiated seeds
used in horticulture and in farming, and had clearly defined
effects. Experiment has shown that compared with control seed the
seed treated gives plants with a better general growth and more
strength; these plants mature earlier, providing a better crop.
(In the case of beet, this latter can be as much as 20%, better,
and in the case of potatoes 10% better).
For the melons shown in the photographs sent to the Congress the
growth is clearly greater for the seed which has been irradiated*.
[* Two photographs exhibited showed the difference between melon
plants grown from activated and non-activated seed about 16 weeks
after planting ]
The Second Method of Irradiation ( which has been patented
) is based on an electromagnetic device combined with an
oscillatoe of these vital radiations.
According to the controls made by others who know how to make use
of radiesthesia, the result of this device's irradiation is an
increase of the field of the tested specimen; an increased "vital
potential" is recorded by the radiesthetist. An interesting
observation of one of these people was the fact that carrying the
appliance in one's pocket seems to increase one's powers of
resistance and to reduce general fatigue.
In the case of irradiated plants we have observed increased growth
and earlier bloom by comparison with the control plants. Trees in
poor condition have gained strength through treatment lasting say,
a year. Water when treated by the device the device acquires new
qualities due to an absorption of this vital radiation.
Solution No. 3 : Neutralization and Simultaneous
Broadcasting of the Vitalizing Radiaition -- Two methods are to be
considered according to what is precisely required.
Method 1 -- To transform the radiations in only a small
area to make this more favorable to life. For this, a small
portable Neutralizer* [ *The Neutralizer and the Vitalizer
exhibited consisted of small flat brass cylinders or capsules
about 43 mm in diameter and 15 mm high. They were hermetically
sealed. ] Model 168-2, which exerts its influence over a radius of
1 m. 30 cm ( 50 inches ); also a Vitalizer, Model 168-3. The
combination of these two can be useful; for instance, to a person
who must remain in a zone of harmful radiations, say during
working hours; or for cattle occupying a small shed which is
in a harmful zone; or again for a tree which fails to thrive
because by mischance it has been planted in a zone of harmful
Method 2 -- To modify the conditions of a whole house or of
a cowshed or similar building situated in a large area influenced
by harmful telluric radiations. Firstly, neutralize completely the
whole area where the building is, by means of an appliance which
emits healthy vitality radiations over a radius of at least 20
meters ( 65 feet ). This appliance must be connected to earth. The
broadcasting derived from this appliance increases the vitality
potential in the area, and for all living organisms increases
their powers of resistance to the various causes of any
disturbance to the vitality factor. Many tests along these lines
are still required from biologists who are skilled in radiesthetic
assessment. It is hoped that these tests will be made in the near
future since the matter is in our opinion of capital importance,
for it concerns our Life. The investigations of British biologists
will be welcomed.

Apparatus for Capture of Hertzian Waves
Inventor(s): LARVARON MAURICE-FRANCOIS +
Apparatus for detecting radio waves. The purpose of the apparatus
is to capture the waves of all kinds emitted by all the bodies of
the animal, vegetable and mineral reigns and those emitted by the
radiotelegraph and xadiotelephone stations. It can replace the
current devices used to pick up hertzian waves: antenna or frame.
Its principle is based on the following observation: a metallic
wire, in the form of a solenoid, enters into vibration under the
influence of the terrestrial waves. It thus acquires the property
of capturing said waves. On the other hand, the shape of this
electromagnetic apparatus enables it to reinforce the sensed
Description and construction.
The apparatus consists of a wire wound in a solenoid: A. The turns
may be wound directly or indirectly. The wire forming the turns is
a few tenths of a millimeter in diameter. The diameter of the
turns varies with the intensity intensity needed.
The starting point of the wire forms a closed loop B. At the C end
of the solenoid the wire communicates with a terminal D of the
same metal as itself. In the center is a bundle of soft E. wire.
The whole is in a wooden boot F.
The terminal D is connected to a detector device. Any kind,
galena, lamp or other.
It goes without saying that the shapes, details and materials and
dimensions of the invention may vary without adversely affecting

Sourcier: the question of clay
December 13, 2015
After having read an old Maurice LARVARON, "Radiobiology,
application to the art of the dowsers" I learned that: Water and
clay can be confused because their alpha and beta radiation,
magnetic North-South, are identical.
However their gamma radiation, electric East-West, is different!
Knowing this, we can no longer be fooled and dig for nothing.
I drew you a dial Wp small dial larvaron
First check with samples that the wavelengths are good (or do your
first calibration if these notions are foreign to you).
Water and clay on the side of 30 cm in alpha radiation
Water at 18, clay at 8 in gamma radiation
Then, under conditions of prospecting on site, on a clayey terrain
that sometimes deceives us, now take care to check with this dial
what is the wavelength of the gamma radiation that caused the wand
or pendulum to react although the research concerned Groundwater

On the verge of radiation and outside the shore of this radiation,
to see if the pendulum gives the same gamma or varies downwards,
confirms the circulation of groundwater in clayey soil.

Dr. Larvaron, son of our scholar colleague, agricultural engineer
Larvaron, a professor at the Agricultural School of Rennes and
author of the interesting work Radiobiology has had the merit of
bringing before the Faculty of Medicine of Paris the formidable
question of "harmful waves." His inaugural thesis on "pathogenic
telluric influences" was supported by him in June 1943 , Under the
chairmanship of Professor Abrami.
The contacts of the radiesthesic or rather radiobiological science
with the official world have so far been so rare that they deserve
to be reported. First, doctor-veterinarian Abel Martin had already
supported his thesis on the "Radiesthetic Diagnosis in Veterinary
Medicine" at the Faculty of Medicine in Paris in 1932. Then, on 24
April 1930, the Association of Radiesthetists of Paris, in the
Great Hall of the Museum, under the auspices of the Société
Française d'Acclimatation and under the effective presidency of
Professor Bresson, Director of the École Vétérinaire d'Alfort ,
Gave a lecture entitled "The harmful waves in relation to the
health of man, animals and plants".
We hope that these various contacts with official scientists will
multiply and that our colleagues radiobiologists will find an
encouragement to multiply the experiments and to perfect their
In his remarkable work, Dr. Larvaron brings some new light to the
question of "harmful waves" which still contains so many obscure
points. He has dealt with the issue on a somewhat broad scale,
guided by prominent radiobiologists, such as his father, who was
previously mentioned, the author of Radiobiology, then Dr.
Régnault de Toulon, author of Biodynamics and Radiations, and
finally Dr Creuzé, former head of the laboratory at the Faculty of
Medicine in Paris, former editor-in-chief of the journal Bio
dynamisme and author of numerous books and articles on
"Biodynamics and Radiation".
Dr. Larvaron, in his thesis, taking into account the novelty and
interest of our radiation, devoted several pages to them: "In
1937, Dr. Peyré established the existence of rectilinear
radiations, Parallel or perpendicular to the magnetic meridian
which may have an adverse effect on certain persons under
specified conditions ".
In a chapter entitled "rayons de Peyre", he also expresses the
idea that the cosmic origin would be the main force causing the
initial departure of this radiation. However, he also cites the
different hypothesis of our friend, the engineer Besnard.
"According to the latter, the earth would behave like a generator
of electric currents, which would go in the east-west direction,
since the earth turns on its axis in 24 hours in the East-West
direction, The Law of Lenz ".
In this hypothesis, the formation of radiations with a magnetic
pace would be determined by electric radiation. These two kinds of
radiation would be crossed by virtue of the law of Ersted,
according to which every rectilinear electric current determines
the formation of a corresponding magnetic field around it,
intersecting with the initial electric current. Under these
conditions, the name of cosmo telluric would not suit our
radiation very well.
Be that as it may, Dr. Larvaron adopting our conclusions, adds:
"From all the above," he says, "we may conclude with Dr. Peyre, as
to the nature of these radiations, lines, or fields of force And
their possible harmfulness, it is electromagnetism and in
particular the electronization of air (above the lines and
interlacing) which give the simplest and most often accepted
explanation. Also see an effect of the general radiation of matter
or of the general radioactivity of the soil, since all bodies can
be regarded as more or less radioactive and possessing some sort
of atomic energy. "
Finally, Dr. Larvaron ends by quoting what we wrote in 1938 in the
Medical Courier: "Of this hypothesis, electromagnetism and
radioactivity which are far from excluding, or even if it was only
a reflection Of cosmic waves, we would nonetheless be in the
presence of a general manifestation of universal energy. "
Such is, inspired by our earlier writings, the general opinion of
Dr. Larvaron on our radiations. As can be seen, he reserved for
them in his inaugural thesis a place in relation to their
importance and novelty, and then approached the classification of
"harmful waves": "We will adopt, he says, with some modifications
The classification established by Mr. H. Mellin ". According to
this author and the work of MM. Mager and Dr. Peyré, harmful
influences can be classified as:
The surface influences, which would be due to three causes:
Geological formations of different nature (magnesia, kaolin, green
Unhealthy (polluted, worn or dead water, sumps, sewers, cesspools,
So-called cosmo influences of Peyré and the influences of depth.
On sea as on land ...
Finally, Dr. Larvaron, after having indicated how to find these
radiations and quotes several of our observations, adds
immediately: "Intrigued, Dr. Peyré, in the spring of 1939,
embarked on a cruise to ascertain if he would find The same
radiation on the sea as on land ".
1. On the steamer Champlain, which led him to Dakar, he found the
same bundles in his cabin and on all the decks of the ship. The
intersections of the spokes remained fixed in their direction with
respect to the magnetic meridian, in spite of the changes in the
course of the ship. We were thus everywhere, on sea as on land, in
the presence of a North-South radiation of magnetic appearance,
attributable to terrestrial magnetism, and of an East-West
radiation perpendicular to the first and of electric appearance.
2. Thus, everywhere, on land as on land, these radiations are
rectilinear; Consequently, it can not be radiation due to other
solely telluric influences, such as those resulting from the
composition of the soil or from the presence in the subsoil of
underground faults or watercourses. Indeed, the latter are always
sinuous, crisscrossing the earth's crust following the chance of
fractures of the ground.
3. Cosmo-telluric rays, so-called Peyre's rays, would therefore
cover our sphere with a network limiting virtually neutral grid
zones, all giving the appearance of an immense checkerboard or an
enormous net enveloping our entire globe. These radiations would
partition the atmosphere and the soil.
4. In the atmosphere, they would rise from the North-South and
East-West divisions encountered on the ground.
The various explanations undertaken, relating to their nature,
conclude that they are of an electromagnetic nature.
1. Experimentally, it can be seen that they determine, above all
in their interlacing, an ionisation of the air which is superior
to that found at other points. Messrs. Besnard and Lambert have
observed this on several occasions and on different occasions,
using a highly sensitive electrometer with gold leaf. "It is to
this degree of maximum ionization that would be the greatest
2. We can not praise Dr. Larvaron for his dual merit, first of
all, in bringing the question of harmful waves before the Faculty
of Medicine in Paris, and then of having shown, "Peyré rays" of
such a broad understanding.
