 lated when boiled, and likewise when mixed with nitric acid or 

 with alcohol. The first portion collected was acid, the last por- 

 tion alkaline, and was composed of,

The solid matter consisted of osmazome, of a peculiar animal 

 matter, coloured red by chlorine, and discoloured by a larger 

 quantity of that reagent, and of casein and albumen. When this 

 solid matter was incinerated, it left carbonate of soda and chlo- 

 ride of sodium, with a trace of sulphate and phosphate of soda, 

 and of carbonate and phosphate of lime.

From this analysis it appears that the pancreatic juice of the 

 dog has no resemblance to saliva. The substance rendered red 

 by a little chlorine was soluble in alcohol and not in water. It 

 constitutes the peculiar and characteristic constituent of pancrea- 

 tic juice, and is therefore called pancreatin. 



The pancreatic juice of the sheep was similar in appearance to 

 that of the dog, but more watery, the solid matter in it amount- 

 ing only to 3-65 per cent. This liquid was found to contain,

From -the solid matter they extracted osmazome and casein, be- 

 sides the coagulated albumen. Whether any pancreatin existed 

 in it was doubtful. At any rate, the quantity was too small to 

 be detected.
