with a shivering of short duration in some of them, and which, in others, may go on increasing into a progressive, and even fatal, coldness, if the surgeon does not struggle early and very energetically against this dangerous tendency. I have had already many times occasion to call the attention of my colleagues, at the " Societe de Chirurgie," to this kind of acci. dent. The first time that I observed it was in a patient at the Hopital St. Antoine, upon whom I had performed the operation for stone by the bi-lateral method, with the lithotome of Dupuytren. , The patient had been taken back to his bed after the operation, no accident had taken place, he had recovered consciousness, and I had recommended perfectly " my internes" to attend to the state of the patient. Nevertheless, at the moment of leaving the hospital, I wished to I found him seized with a shivering so see him once more. intense and determining such deep prostration, that I had no doubt, if unattended to, at the end of half an hour, or perhaps an hour, it would have infallibly proved fatal. I occupied myself then to establish the calorification by all the means that I had at my disposition at the moment. The first attempts produced but a slightly-marked effect; but, in persevering in the use of the same means-viz., friction, with hot brandy and camphor, hot sheets, bottles of hot water to the feet, hot sugared wine internally, I succeeded in reanimating my patient; and when I left the hospital, he was in a

This colour proved evidently that the blood had not undergone in favourable condition. This man was perfectly cured. I have the lungs a sufficient revivification or oxygenation, and that not the least doubt that if I had not returned he would have there was from that time a commencement of asphyxia.
