the time of the experiment in 1824, it was 66^, in 1825, 84", 

 a difference of 18°. 



This experiment was begun on the 12th of July, 1825, at 

 three o'clock. The temperature of the atmosphere was 84°, 

 that of both horns exactly 98 j . Immediately after Mr. Mayo 

 had divided the nerves, the heat of that horn was diminished 

 to 93 i°, and the heat of the other encreased to 99°. 



The following register, showing the changes that took 

 place in the temperature of the horns and atmosphere, was 

 regularly filled up every day at three o'clock. 



After the two horns had become of the same temperature 

 the buck was allowed to join the herd. On the 28th of July 

 it was killed for the use of the table, which gave me an op- 

 portunity after death of examining the parts that had been 

 operated on. The horns had not shed their velvet, were 

 exactly of the same size, and equal in solidity.
