ANIMAL HEAT. 



General considerations Limits of variation in the normal temperature in man 

 Variations with external temperature Variations in different parts of 

 the body Variations at different periods of life Diurnal variations Rela- 

 tions of animal heat to digestion Influence of defective nutrition and in- 

 anition Influence of exercise, mental exertion, and the nervous system, 

 upon the heat of the body, 394 



CHAPTER XIV. 



SOURCES OF ANIMAL HEAT. 



Connection of the production of heat with nutrition Seat of the production of 

 animal heat Relations of animal heat to the different processes of nutri- 

 tion Relations of animal heat to respiration The consumption of oxygen 

 and the production of carbonic acid in connection with the evolution of 

 heat Exaggeration of the animal temperature in particular parts after 

 division of the sympathetic nerve and in inflammation Intimate nature of 

 the calorific processes Equalization of the annual temperature, . 418
