During the ewarming of beet the hive temperature may Hk from 8S* to 40° (898 to 104 F.). All cold-blooded animala have probably a higher temperature in the breeding* aeaaon. In our domestic mammals the normal temperature in not widely different from that of man. In the horse the aver- age is 37-5° to 38° (99*5 to 1004 F.); in the ass, 88° to 89-ft° (1004 to 108 F); in the ox, 88° to 88*5° (100*4 to 101'8 F.); in the sheep and pig, 89° to 40° (108'8 to 104 F.); in the oat, 88-5° to 89° (101-8 to lOS-2 F.); in the dog, 88S° (101'3 F.). Variations in the average temperature are dependent on numerous causes which may affect either the heat production or heat loss : 1. CThange of climate has a very slight but real influence, the temperature being elevated a fraction of a degree when an individual travels from the poles toward the equator, and the same may be said of the effect of the temperature of a warm summer day as compared with a cold winter one. The wonder is that, considering the external temperature, the vari- ation is 80 light 2. Starvation lower* the temperature, and the ingestion uf food raises it slightly, the latterincreasing, the former decreasing, the rate of the metabolic processes. 3. Age has its influence, the very young and the very old, in whom metabolism (oxidation) is feeble, having a lower temperature. This especially applies to the newly bom, both among man-^ kind and the lower mammals; and, as might be supposed, the temperature falls daring sleep, whe
