Physiology is the science of the fuuctioiit? of living tissue (here conlinetl to animals). 

 The main facts and theories of animal jihysiology apply to man and the various 

 domesticated animals, and constitute the suhject of general physiology. If preferred, 

 a course in human pliysiology covering sul)stantially tlie same toj)i(>s, may Ix' su1)sti- 

 tutcd. Ill the agricultural college the liygiene of <lomesticated animals will ordinarily 

 be taught imder the separate subject of zootechny, and the same may be said for 

 metalM)lism and digestion in different s^iecies of animals. Illustrative materials and 

 simi)le demonstrations will b<> used in connection with the lectures or text-book.
