LIVER. 323 



kaline lactate, as boiling alcohol did not extract any from it. 

 Indeed that reagent dissolved very little of anything from it. 



The portion insoluble in alcohol being dissolved in water and 

 mixed with the infusion of nut-galls, let fall a prepipitate, which 

 Braconnot considered as albumen still remaining in it. The excess 

 of tannin being removed by the peroxide of tin, the remaining li- 

 quid contained a matter, which, being evaporated, left a substance 

 similar to a vegetable extract, and containing a little azote. Be- 

 ing dissolved in water, it became acid without putrefying. 



Braconnot found ox-liver to be composed of the following con- 

 stituents : 



Vessels and membranes, . 18 '94 

 Parenchyma, . . 81-06 



100-00 



The parenchyma contained the following substances : 

 Water, . 68-64 



Dried albumen, . . . 20-19 



Matter (containing little azote) soluble in 1 

 water, and little soluble in alcohol, J 

 Oil similar to cerebrote, . . 3-89 



Chloride of potassium, . . 0*64 



Ferruginous phosphate of lime, . 0-47 



Acidulous salt insoluble in alcohol, , 0*10 



Blood, a little.

Fromherz and Gugert analyzed the liver of a healthy young 

 man who had been executed. Their process was as follows : 



After wiping the liver clean from blood, they cut it into small 

 pieces, and digested it in cold water till the liquor ceased to dis- 

 solve anything. The solution was slightly red, mucilaginous, 

 and muddy. Being separated by filtration from the albumen, it 

 was evaporated to the consistence of a syrup. It left an extrac- 

 tive matter, from which boiling alcohol extracted (besides ex- 

 tractive) a substance, which partially precipitated on cooling in 

 white flocks. This substance Fromherz and Gugert considered 

 as casein. But they do not mention the characters which in- 

 duced them to draw this conclusion. When calcined, it left some 

 chloride of potassium and phosphate of lime,
