118 how those flies carefully avoided settling in the compartment of blue colour.
2Regnault made use of this discovery with success, in 1911, preserving from the flies, in the hospital of Saint Mandrier, those wounded in the explosion of the battleship Liberté, by painting blue the walls of the room where the patients were.
3For the frog, on the contrary, Torelle has found that the zone they prefer is between red and blue.
4A notable fact, as regards experimentation on men, is the one Abrams observed on placing a red glass before one eye of a person facing West and standing on aluminium plates connected to earth.
5Observing the pulsations of the radial arteries at both wrists, he observed that the pulsations of the radial on the same side as the eye before which the red glass stood were modified, while those of the other radial continued normal.
6For woman, the reaction was inverse, which must almost certainly be in relation with the difference of polarity existing between the two sexes.
7An English physician observed that if the seven colours of the spectrum are presented successively to a person, it is noted that the pulse reacts differently for each colour and that it quickens when a colour is presented whose wavelength provokes perturbations in the characteristic wavelength of the person [Sic: the Spanish prints “de 1a persona”, with a numeral].
8Giuseppe Calligaris, professor of neuropathology at the University of Rome, found experimentally, during long studies pursued with admirable constancy on the “linear chains of the body and of the spirit”, various physical and metapsychical results, either due to the influence of a colour, or due to the stimulation of a cutaneous plaque that causes colours to be perceived.
9In consideration of the enormous importance of those experiments, we shall relate some: 1) There exists a general cutaneous field which, if illuminated with yellow light, makes one see what is behind one’s own body.
10This cutaneous field is of rectangular form and is found on the anterior surface of the left shoulder, between the mammillary line and the upward prolongation of the anterior axillary line; and between an upper plane passing two transverse fingers below the course of the lateral line of the body, on the shoulder, from the acromio-clavicular articulation, and a lower plane passing 3 cm. above the fold of the armpit.
11If the left pectoral region and the shoulder are covered with a white cloth, leaving free the cutaneous field described, and clear yellow light coming from any luminous source is projected upon it, the subject is induced to perform automatically all his habitual gestures, sees the contours of things as if blurred, and presents an affirmative tic of the head.
12After some minutes of irradiation of the field with the colour, the subject sees an object or a person situated behind his back at the distance of one metre, or also sees the first object situated in a straight line behind him up to the distance of 10 metres.
13The experiment gives the same result on applying a rectangle of yellow paper upon the cutaneous field instead of illuminating it with light of the same colour. (G, Calligaris.
14“Le meraviglie dell’Eteroscopia”. 1934, pp. 26 and 27). 2) There exists a cutaneous plaque of diameter of almost 12 mm., found on the left shoulder on the mammillary line, which, if stimulated with a small faradic electrode or a metallic surface of the same diameter as the plaque, and cold, the subject will feel pains in the lower third of the left leg, pain below the left armpit, pain radiating from the left little finger up to the corresponding shoulder.
15Now, if during the performance of this experiment other plaques are stimulated which permit the stereoscopic images of an internal organ, a tissue, etc., to be seen, then the subject will see those organs or tissues with their natural colours.
