    EXPERIMENT 4 Death from Chloroform; Resuscitation Begun 6 Minutes After Cessation of Circulation; Total Duration of Anemia, 83^ Minutes July, 1906. Young fox terrier; weight, 7.3 kilos; condition, good. Experi- ment conducted as in Experiment i. Total duration of anesthesia, 15 minutes. 9.57 A. M.—Respiration ceased. 9.58. —Circulation ceased. 9.59.30. —Several weak respiratory movements occurred, and the heart beat feebly again for about 10 seconds. The ac- tion was too weak to produce a palpable pulse in the carotids. 10.04. —Began to resuscitate, 6 minutes after cessation of circu- lation. 10.06.30.—The heart began to beat again, making the total duration of cessation of circulation 8^ minutes. 10.09. —Spontaneous respiration began, 2^ minutes after return of the circulation. 10.20. —The respiration was regular. 10.23. —The conjunctival reflex was first obtained and normal spontaneous winking noted, 163/2 minutes after return of the circulation. The fore leg reflex was first ob- tained 3^ minute later, and was more marked in the right leg. (Note.—This was the first experiment in which the leg reflex was obtained in a fore leg before being obtained in a hind leg.) The knee-jerks ap- peared somewhat later, and first in the right leg. 11.26. —The right knee-jerk was strong, the left weak. The dog began to utter an inarticulate cry. Rectal temperature, 36.1° C. 11.32. —The fore legs began to stiffen. The hind legs were still relaxed. 11.45. —The hind legs were considerably more spastic. There was no definite pupillary reflex. Temperature, 36.6°. 2.30, —Temperature, 36.1°. The dog was still unconscious, with no indication of even incoordinated muscular movements. The hind legs were very spastic, while the fore legs had become flaccid. The knee-jerks were exaggerated. There v/as no scratch reflex. The pupils were con-
