was much larger than in the two preceding. The con- 

 tents were of a less firm consistence, but did not display 

 the same unaltered appearance as in the large arch of the 

 stomach of the former rabbit, being almost as much digest- 

 ed as the best concocted portion in the stomach of that 

 animal. The large intestines were in the same condition 

 as those of the preceding rabbit. The lungs and heart 

 weighed thirteen drachms and a half.* 



EXPERIMENT II. 



From the sudden death of the last rabbit, and from the 

 whole of the thoracic symptoms, I proposed, in this ex- 

 periment, to obviate the severity of the consequences by 

 dividing the trachea, and adapting to it a large brass tube, 

 to allow the atmospheric air to enter the lungs freely. The 

 three rabbits in this experiment were full grown, and ap- 

 peared equally healthy. After fasting for twenty-three 

 hours they were allowed to eat plentifully of cabbage leaves 

 five hours before the operation, immediately before which 

 a small quantity was again given. 



Temperature of this rabbit 103. The trachea was divid- 

 ed, and the tube attached as described. About half an 

 inch of the par vagum on both sides was cut out. The 

 experiment commenced at one o'clock P. M. 



At three o'clock the temperature was 104. The rabbit 

 breathed as easily as in the state of health. Tantillum

* To ascertain the weight of the lungs and heart of a rabbit 

 in health, the viscera were taken from two adult rabbits 

 that had been instantaneously killed. In the one they were 

 found to weigh two drachms and a half, in the other three 

 drachms and one scruple.
