I cannot well explain the difference which exists between 
the results of the preceding experiments, and those of Messrs, 
Coleman and Cooper, which are directly opposite. Can the 
mode in which the animals they experimented on were put 
to death, be the cause of the want of agreement ? In death by 
asphyxia, there is generally an accumulation of blood in the 
right ventricle, and in many instances I have observed, when 
the right ventricle has been distended with blood, little differ- 
ence of temperature between the two sides of the heart. 
To describe all the experiments that I have made to ascer- 
tain the temperature of different parts of the animal body, 
would extend this paper to an unusual length, and there is 
the less occasion for a long description, as the comparative 
results were very similar. It will be sufficient therefore here
