1912.] Destiny of Cholesterol in the Animal Organism. 389 



extract yielded 01299 grm. of cholesteride, equal to 0*0421 per cent, free 

 cholesterol. The saponified extract yielded 0*1820 grm. of cholesterol, equal 

 to 0*0584 per cent, total cholesterol, and, by difference, the ester was 0'0163 

 per cent. 



150 grm. were taken from the cholesterol-injected animal. The unsaponified 

 half yielded 0*1844 grm. of cholesteride, equal to 0*0299 per cent, free 

 cholesterol. The saponified half yielded 0*3868 grm. of cholesteride, equal 

 to 0*1253 per cent, total cholesterol; the ester is, therefore, 0*0656 per cent. 



The lungs were not examined in these cases. 



The brains; from the control rabbit the brain weighed 11*927 grm. Half 

 the saponified half yielded 0*3530 grm. of cholesteride, equal to 2*428 per cent, 

 free cholesterol. There was no ester. The brain from the cholesterol-injected 

 rabbit weighed 15*98 grm., 0*2277 grm of cholesteride was obtained, equal to 

 2*2794 per cent, free cholesterol. 



Cholesterol-content of these Organs of Rabbits during Inanition. 

 Experiment IX : — 



A fat rabbit (I), of 3 kgrm. weight, fed for a few clays on bran, then kept 

 free of food for six days, water being allowed. 



Experiment X : — 



A thin rabbit (J), of 1*9 kgrm. weight, similarly treated. 



The bloods; from Eabbit I were obtained 71*03 grm. of blood. The 

 unsaponified half yielded 0*1523 grm. of cholesteride, equal to 0*1042 per cent, 

 of free cholesterol. The saponified half yielded 0*1956 grm. of cholesteride, 

 equal to 0*1338 per cent, total cholesterol; the ester was, therefore, by 

 difference, 0*0296 per cent. 



From Eabbit J were obtained only 40 grm. of blood. The unsaponified 

 half yielded 0*1003 grm. of cholesteride, equal to 0*1219 per cent, free 

 cholesterol. The saponified half yielded 0*1424 grm. of cholesteride, equal 

 to 0*1730 per cent, total cholesterol. The ester cholesterol was therefore, by 

 difference, 0*0512 per cent. 



The kidneys from Eabbit I weighed 15*48 grm. The unsaponified half of 

 the extract yielded 0*1295 grm. of cholesteride, equal to 0*4009 per cent, free 

 cholesterol. The saponified half yielded 0*1867 grm. of cholesteride, equal to 

 04562 per cent, total cholesterol. The ester, by difference, was, therefore, 

 0*0698 per cent. 



From Eabbit J the kidneys weighed 10*93 grm. The unsaponified half of 

 the extract yielded 0*0869 grm. of cholesteride, equal to 0*3864 per cent, free 

 cholesterol. The saponified half yielded 0*1026 grm. of cholesteride, equal to
