Respiration waves, etc. : Vagus 

 stimulated : secondary at 10 

 mm., no obvious effect. 



Respiration waves indistinct. 

 Pulse movements large (8 to 

 10 mm.) and less irregular. 



Respiration waves indistinct. 

 Pulse movements irregular ; 

 majority about 2 mm., but 

 every fourteenth or sixteenth 

 as much as 15 mm. 



Do. do. 



Respiration waves indistinguish- 

 able (at 5 - 8, however, the re- 

 spirations were 22 per 60 sec, 

 full and regular). Pulse move- 

 ments are nearly regular and 

 large, 9 to 11 mm. 



Do. do. Pulse movements, 

 however, again became irregu- 

 lar at 5.8.40. 



Vagus stimulated for 6 sec. : 

 secondary at 10 mm. ; at end 

 of stimulation four slow beats, 

 and slight fall of pressure. 



Respiration waves well marked. 

 Pulse movements regular, and 

 much smaller than before. 



Respiration waves indistin- 

 guishable. Pulse movements 

 very irregular, and varying 

 in size from 3 to 10 mm. 



Respiration waves indistin- 

 guishable ; respirations 

 counted at 5.22 were 22 per 

 60 sec, regular and full. 

 Pulse movements less irregu- 

 lar and smaller, 2 to 4 mm. 

 At 5.20.12 pulse move- 

 ments again became as at 

 4.18.40. 



Vagus stimulated : secondary 

 at 20 mm., no effect. 



Respiration waves indistin- 

 guishable ; but when counted 

 at 5.22, the respirations were 

 22 per 60 sec, full and regu- 

 lar. Pulse movements regu- 

 lar and large (9 to 11 mm.), 

 they became so at 5.23.42, 

 and continued till 5.24.18.
