The irregular pulse movements 

 became regular again for a 

 few seconds, but afterwards 

 again irregular, and they con- 

 tinued irregular, as in the 

 first portion of the tracing, 

 for 5 min. Rabbit quiet, and 

 breathing well.

 sec. Pulse movements less 

 irregular, but smaller (from 

 4 to 9 mm.), and more fre- 

 quently the latter than the 

 former. Two or three brief 

 and weak spasms occurred at 

 4.45. 



The pulse movements gradually 

 became smaller, until, at 4.49, 

 they had assumed the charac- 

 ters shown in tracing No. 6.

Respiration waves indistinguish- 

 able. Respiration slow, irre- 

 gular, and shallow. Pulse 











































movements regular and large, 























5 mm. After being irre- 























gular, though still large, for 























several seconds, they became 























again regular and very large 























at 5.12, immediately before 























which some slight spasms 























occurred.
