cerned, similar results had been obtained by Schreiner 

 (Chem. Centralbl., III. Folge, IX. Jahrg.), and he 

 desired to present his observations in these particu- 

 lars simply as confirmatory of those of that observer. 

 Artificial digestions showed that milk was more 

 readily digested when raw than when boiled. This 

 was further confirmed by a comparative examina- 

 tion and weighing (in over fifty cases, and in which 

 he was aided by Dr. Roussel) of the contents of the 

 stomach after raw and boiled milk had been, in 

 different individuals, undergoing actual gastric di- 

 gestion. In these cases the residue found in the 

 stomachs of those persons receiving boiled milk was 

 greater than the similar residue found in the stomachs 

 where raw milk had been undergoing digestion for 

 the same length of time. [In obtaining the gastric 

 contents of the individuals under observation, tur- 

 peth mineral was used in the first series of eight 

 persons with most unsatisfactory results. It was 

 always thereafter substituted by hypodermic injec- 

 tions of apomorphia.]
