EXPERIMENT I. 



The influence of the par vagum on the Junction of 

 digestion. The three rabbits in this experiment were 

 adults, and about the same size. They were fed at half 

 past six o'clock, A. M. with cabbage leaves ; they had 

 previously fasted sixteen hours. This rabbit had the par 

 vagum divided on one side only, at eight o'clock. Tem- 

 perature before experiment 



Time. Temperature. Observations. 



10 o'clock A. M. 100 Apparently cheerful. 

 12, noon, 10l ditto. 



2, P. M. 102 ditto. 



6, P. M. 103 ditto. 



At six o'clock, p. M. this rabbit was killed. 



Dissection. On opening the chest the lungs collapsed, 

 but were slightly infiltrated ; the heart appeared in the 

 natural state ; nothing worthy of particular remark in the 

 thorax. The stomach, of a smaller size than in the two 

 others, was filled with a homogeneous mass, in which the 

 well-marked characters of vegetable food were absent. 

 The contents of the large intestines were well concocted. 

 The weight of the lungs and heart of this rabbit was three 

 drachms and a half. 



In the following, the par vagum was divided on both 

 sides. Temperature of the rabbit, before experiment, 105. 

 The operation was performed a few minutes after the pre- 

 ceding. 



Time. Temperature. Observations. 



10 o'clock A. M. 98 Respiration very laborious. 



12, noon, 97 ditto. 



2, P. M. 96 ditto. 



6, P. M. 93 ditto. 



At six o'clock, P. M. it was killed.
