MORBID TISSUES, 481 



and ether, submitted to ultimate analysis. Independently of 

 salts, it yielded : 



Carbon . . 54-125 -, 



Hydrogen . . 7 '281 I which corresponds with the 



Nitrogen . . 15-892 | formula C 46 H 38 N 6 O la 



Oxygen . . 22- 702-* 



Hence the scrofulous matter may be regarded as formed from 

 protein by the removal of two atoms of carbon and oxygen, 

 and the addition of two of hydrogen, or making the amount of 

 carbon the same in the scrofulous mass and the protein, we have : 



1 At. scrofulous matter . = Pr -f- HO + 2 H. 



Carcinoma uteri and scirrhus testiculi were examined by 

 Scherer in a similar manner. 



L'Heretier has made the three following proximate analyses 

 of scirrhus : 



Water 



Albumen 



Fibrin . 



Gelatin 



Fat 



Phosphorized fat . . . 6-00 



Peroxide of iron . . . 1-15 1-25 traces 



Yellow pigment . . . 7 '00 



Salts . . 12-60 9-55 10-13 ] 



A fatty tumour analysed by Nees von Esenbeck 1 contained 

 23-0 of solid fat, 12'0 of extract of flesh, 11-0 of gum-like animal 

 matter, 23'0 of albumen, 19*0 of phosphate of lime, 2'0 of car- 

 bonate of lime, and 1-5 of carbonate of magnesia. It is not 

 stated whether this solid fat contained cholesterin; in all pro- 

 bability it did, as this fat is of frequent occurrence in fatty 

 tumours. In a fatty tumour examined by J. Miiller there 

 were acicular crystals mixed with a gray substance which was 

 deposited in vesicles and dissolved in boiling water, from which 

 it was not precipitated by acids or the ordinary metallic salts. 

 The crystals were insoluble in acids, water, or alcohol, but dis- 

 solved in ether ; hence they probably consisted of cholesterin.
