ANIMALS AND ALCOHOL 85 



This then was the first great lesson which Bum and 

 Tipsy taught the scientists. But this was not enough;

 machines showed that although Bum and Tipsy had now 

 recovered from their illness, and although they were 

 cheerful and had good appetites, still they were not so 

 active as Nig and Topsy ; in fact, the machines proved 

 that they did only about half as much running around 

 as the other two dogs.
