pearance of fat has been ascribed to the failure in the 

 supply of pancreas-juice. In lientery the pancreas as 

 well as the stomach and pylorus is probably at fault. 



^e digestion in the small intestine is very imper- 

 fectly known, and requires particular and great re- 

 searches in the future. In this part of the body is the 

 constant and principal seat of diseased processes of the 

 greatest importance, e. g. 9 typhus and typhoid fever, 

 cholera, and others, not the least important amongst 

 them the aestival and autumnal diarrhoea so fatal to 

 many persons in every year without special epidemic 

 influences. 



human f and Glycerine is a tridynamic alcohol, constructed ac- 

 body ' cording to the type of water thrice condensed. In this 

 type there are six atoms of hydrogen replaceable ; 

 when three of these are replaced by the tridynamic 

 radical glyceryl, glycerine is formed. Glycerine, 

 therefore, has three atoms of typical hydrogen, 

 which can be replaced by three atoms of a mono- 

 dynamic body or one atom of a tridynamic body. It 

 is not necessary to substitute all the hydrogen at once 

 when we work synthetically, but in animal bodies all 

 the hydrogen is always replaced by fatty acids. A fat 

 is thus shown to be a body of the type of three atoms 

 of water condensed to one, thus 



in which three atoms of hydrogen are replaced by one 

 atom of glyceryl 111 and three others by three atoms of
