The influence of diet on the heat production during mechanical 



work in the dog. 



By Graham Lusk. 



[From the Physiological Laboratory of the Cornell University 

 Medical College in New York City.] 



The following table shows that when a dog runs at the rate of 

 about 2Y2 miles an hour the heat production is almost exactly 

 the same whether the dog has had no food or whether 70 grams of 

 glucose have been administered. In the resting dog 70 grams of 

 glucose would have increased the heat production six calories.
