Notes. 



Respiration waves indistinguish- 

 able. Respiration slow, irre- 

 gular, and shallow. Pulse 

 movements regular and very- 

 large, 12 to 14 mm. At 

 5.12.26, the pulse movements 

 became irregular, though re- 

 maining large ; and the aver- 

 age pressure rose till, at 

 5.12.34, the maximum pres- 

 sure was 132 mm. ; and at 

 the same time the pulse move- 

 ments became much smaller 

 (5 to 6 mm.), and their rate 

 increased to 72 per 60 sec. 



Pulse movements nearly regular 

 and small, 2 to 3 mm. Re- 

 spiration very slow, shallow, 

 and irregular, and at rate of 

 about 20 per 60 sec. 



Pulse movements as above, but 

 smaller. They continued as 

 in tracing till 5.14.50, when 

 they became irregular, and 

 the blood-pressure began to 

 fall, and some general con- 

 vulsions occurred. 



Blood-pressure fell in 5J sec. 

 from 96 mm. to 38 mm., and 

 the pulse movements be- 

 came very slow, 2 only occur- 

 ring in 15 sec, but with large 

 pulse movements. Respira- 

 tion very infrequent, shallow, 

 and irregular ; long pauses 

 without any. 



The pulse movements soon 

 afterwards became rather 

 more frequent, and the blood- 

 pressure rose a little. 



Pulse movements 10 and 12 mm. 

 The rate gradually increased 

 and the movements decreased 

 proportionately in size, and 

 the blood-pressure rose. 



Pulse movements 7 to 10 mm. 

 Respiration has almost ceased. 

 Eyelids and cornea insensitive. 



Some convulsions, during which 

 blood-pressure rose to 126 

 mm., and the pulse move- 

 ments became small and 

 rapid. In a few seconds the 

 blood-pressure again rapidly 

 fell, and irregular slow pulse 

 movements of larger size 

 occurred. These continued 

 until 5.20, when the heart's 

 action altogether ceased. 



Pulse movements about lg mm.
