Rh following January. As seen from the chart, Fig. 7, they have practically attained their growth at this time. During the following year it was possible to increase the dose only five cubic centimetres—to the amount given at present. February 21, 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 corresponds 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 followed

in the matter. While it may not be the golden physiological mean, it would seem to be safely within the physiological extreme, as the perfect general health of the dogs has shown.

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