Knowing that he had passed several nights without sleep, and endured extraordinary fatigues, I did not doubt that he had fallen into that profound and lethargic sleep which is superinduced by intense cold, and which if too far prolonged slackens respiration and circulation to a point where the most delicate physiological tests are necessary to discover the continuance of life. The pulse was insensible; at least my fingers, benumbed with cold, could not feel it. My hardness of hearing (I was then in my sixty-ninth year) prevented my determining by auscultation whether the beats of the heart still aroused those feeble though prolonged vibrations which the ear continues to hear some time after the hand fails to detect them.
The colonel had reached that point of torpor produced by cold, where to revive a man without causing him to die, requires numerous and delicate attentions. Some hours after, congelation would supervene, and with it, impossibility of restoration to life.
I was in the greatest perplexity. On the one hand I knew that he was dying on my hands by congelation; on the other, I could not, by myself, bestow upon him the attentions that were indispensable. If I were to administer stimulants without having him, at the same time, rubbed on the trunk and limbs by three or four vigorous assistants, I would revive him only to see him die. I had still before my eyes the spectacle of that lovely young girl asphyxiated in a fire, whom I succeeded in reviving by placing burning coals under the clavicles, but who could only call her mother, and died almost immediately, in spite of the administration of internal stimulants and electricity for inducing contractions of the diaphragm and heart.
And even if I should succeed in bringing him back to health and strength, was not he condemned by court-martial? Did not humanity forbid my rousing him from this repose akin to death, to deliver him to the horrors of execution?
I must confess that in the presence of this organism where life was suspended, my ideas on reanimation took, as it were, fresh hold upon me. I had so often desiccated and revived beings quite elevated in the animal scale, that I did not doubt the success of the operation, even on a man. By myself alone I could not revive and save the Colonel; but I had in my laboratory, all the instruments necessary to desiccate him without assistance.
To sum up, three alternatives offered themselves to me. I. To leave the Colonel in the crenellated tower, where he would have died the same day of congelation. II. To revive him by stimulants, at the risk of killing him. And for what? To give him up, in case of success, to inevitable execution. III. To desiccate him in my laboratory with the quasi certainty of resuscitating him after the restoration of peace. All friends of humanity will doubtless comprehend that I could not hesitate long.
I had Sergeant Garok called, and I begged him to sell me the body of the Colonel. It was not the first time that I had bought a corpse for dissection, so my request excited no suspicion. The bargain concluded, I gave him four bottles of kirsch-wasser, and soon two Russian soldiers brought me Colonel Fougas on a stretcher.
As soon as I was alone with him, I pricked one of his fingers: pressure forced out a drop of blood. To place it under a microscope between two plates of glass was the work of a minute. Oh, joy! The fibrin was not coagulated. The red globules appeared cleanly circular, flattened, biconcave, and without notches, indentations or spheroidal swellings. The white globules changed their shape, taking at intervals the spherical form, and varying their shapes again by delicate expansions. I was not deceived then, it was a torpid man that I had under my eyes, and not a dead one!
I placed him on a pair of scales. He weighed one hundred and forty pounds, clothing included. I did not care to undress him, for I had noticed that animals desiccated directly in contact with the air, died oftener than those which remained covered with moss and other soft materials, during the ordeal of desiccation.
My great air-pump, with its immense platform, its enormous oval wrought-iron receiver, which a rope running on a pulley firmly fixed in the ceiling easily raised and lowered by means of a windlassall these thousand and one contrivances which I had so laboriously prepared in spite of the railleries of those who envied me, and which I felt desolate at seeing unemployed, were going to find their use! Unexpected circumstances had arisen at last to procure me such a subject for experiment, as I had in vain endeavored to procure, while I was attempting to reduce to torpidity dogs, rabbits, sheep and other mammals by the aid of freezing mixtures. Long ago, without doubt, would these results have been attained if I had been aided by those who surrounded me, instead of being made the butt of their railleries; if our authorities had sustained me with their influence instead of treating me as a subversive spirit.
I shut myself up tête-à-tête with the Colonel, and took care that even old Getchen, my housekeeper, now deceased, should not trouble me during my work. I had substituted for the wearisome lever of the old fashioned air-pumps, a wheel arranged with an eccentric which transformed the circular movement of the axis into the rectilinear movement required by the pistons: the wheel, the eccentric, the connecting rod, and the joints of the apparatus all worked admirably, and enabled me to do everything by myself. The cold did not impede the play of the machine, and the lubricating oil was not gummed: I had refined it myself by a new process founded on the then recent discoveries of the French savant M. Chevreul.
Having extended the body on the platform of the air-pump, lowered the receiver and luted the rim, I undertook to submit it gradually to the influence of a dry vacuum and cold. Capsules filled with chloride of calcium were placed around the Colonel to absorb the water which should evaporate from the body, and to promote the desiccation.
I certainly found myself in the best possible situation for subjecting the human body to a process of gradual desiccation without sudden interruption of the functions, or disorganization of the tissues or fluids. Seldom had my experiments on rotifers and tardigrades been surrounded with equal chances of success, yet they had always succeeded. But the particular nature of the subject and the special scruples imposed upon my conscience, obliged me to employ a certain number of new conditions, which I had long since, in other connections, foreseen the expediency of. I had taken the pains to arrange an opening at each end of my oval receiver, and fit into it a heavy glass, which enabled me to follow with my eye the effects of the vacuum on the Colonel. I was entirely prevented from shutting the windows of my laboratory, from fear that a too elevated temperature might put an end to the lethargy of the subject, or induce some change in the fluids. If a thaw had come on, all would have been over with my experiment. But the thermometer kept for several days between six and eight degrees below zero, and I was very happy in seeing the lethargic sleep continue, without having to fear congelation of the tissues.
I commenced to produce the vacuum with extreme slowness, for fear that the gases distributed through the blood, becoming free on account of the difference of their tension from that of rarified air, might escape in the vessels and so bring on immediate death. Moreover, I watched, every moment, the effects of the vacuum on the intestinal gases, for by expanding inside in proportion as the pressure of the air diminished outside of the body, they could have caused serious disorders. The tissues might not have been entirely ruptured by them, but an internal lesion would have been enough to occasion death in a few hours after reanimation. One observes this quite frequently in animals carelessly desiccated.
