THE PHYSIOLOGY OF ALCOHOL.

following January. As seen from tlie chart, Fig. 7, they have 

 practically attained their growth at this time. During the fol- 

 lowing year it was possible to increase the dose only five cubic 

 centimetres to the amount given at present. February '-^l, 1897, 

 Bum's weight was 9,950 and Tipsy's 10,060 grammes. It thus 

 appears that the physiological limit for a non-intoxicant dose 

 of alcohol in the case of our dogs is about four cubic centimetres 

 per kilogramme. 



It is readily seen that this amount is equivalent for a man 

 weighing seventy kilogrammes to two hundred and eighty cubic 

 centimetres daily and taken at a single dose. This is ten ounces, 

 whereas the physiological limit for man is usually stated as two 

 ounces. This, of course, refers to absolute alcohol, and corre- 

 sponds to nearly three times the amount of moderately strong 

 whisky. It may be contended that this is too much or too little, 

 but it still seems to me that no better rule could have been fol-

 ological mean, it would seem to be safely within the physio- 

 logical extreme, as the perfect general health of the dogs has 

 shown. 



As to details of feeding, each dog receives, in a separate dish
