AND ANIMAL LIFE. 



was little particular to observe ; its appetite appeared as 

 keen as ever, but its respiration was occasionally labori- 

 ous. Its temperature was 104. At half -past seven the 

 following morning this rabbit was found dead, but was still 

 warm. 



Dissection. The lungs were somewhat engorged, and 

 were of a bright Modena colour ; they collapsed but slight- 

 ly on opening the chest. The stomach was large, and its 

 contents were of two very opposite descriptions ; that oc- 

 cupying the cardiac portion was vegetable, slightly divided, 

 but not otherwise altered in appearance ; that of the pylo- 

 ric was well comminuted, and apparently homogeneous. 

 The contents of the large intestines were moderately well 

 concocted. 



The trachea in the following rabbit was divided, and the 

 par vagum on one side only. Temperature of rabbit 105. 



At two o'clock the temperature was 104 ; respiration 

 natural ; great avidity for food. At this time the rabbit 

 alias ascendere sospius conabatur, et, quanguam hebetior 

 erat, nihilommus blandiendo variis modis salacitatis spe- 

 ciem reprccsentabat. This is a phenomenon I cannot in 

 the least account for. A gentleman was with me when I 

 observed the same in Experiment II. I am persuaded 

 that it does not arise from the vigour of the animal, nor 

 from the natural impulse of the feeling ; for, in the present 

 instance, the first selected was a very fine male rabbit, and 

 it very frequently approached, without any discrimination 

 of sex or age, the individuals among which it was placed. 

 It has never occurred when the trachea only was cut, and, 

 since it has happened in these two cases in which the par 

 vagum was divided, it would seem to depend on some de- 

 rangement of the cerebellic system. But, as it is my in-
