ANIMALS AFTER INOCULATION. 217 



kept under as good general conditions as possible. For 

 the first week the rabbits received each 100 grammes of 

 green food (cabbage and turnips) daily, and the guinea- 

 pigs 30 grammes each of the same food. During the 

 second week this daily amount of food was doubled ; 

 during the third week it was quadrupled, and for the 

 fourth and fifth weeks they each received an excess of 

 food daily, consisting of green vegetables and grain 

 (oats and corn). By reference to the charts sudden 

 diurnal fluctuations in weight will be observed that do 

 not correspond in all instances with scarcity or sufficiency 

 of food. With the rabbits there is a gradual loss of 

 weight with the smaller amounts of food, which losses 

 are not totally recovered as the food is increased. With 

 the guinea-pigs there is likewise at first a loss, but after 

 a short time the weight remains tolerably constant, and 

 is not as conspicuously affected by the increase in food 

 as one might expect. From the recorded temperatures 

 one sees the peculiar fluctuations mentioned. To just 

 what they are due it is impossible to say. It is mani- 

 fest that the normal temperature of these animals, if we 

 can speak of a normal temperature for animals present- 

 ing such fluctuations, is about a degree or more, Centi- 

 grade, higher than that of human beings. The animals 

 from which these charts were made were not inoculated, 

 nor were they subjected to any operative procedures 

 whatever, the only deviations from normal conditions 

 being the variations in the daily amount of food given. 

 In certain instances, however, there will be noticed a 

 constant tendency to diminution in weight, notwith- 

 standing the daily fluctuations, and after a time a con- 

 dition of extreme emaciation may be reached, the animal 

 often being reduced to from 50 to 60 per cent, of its
