1912.] Destiny of Cholesterol in the Animal Organism. 387 



Muscle. 100 grm. taken. Half the extract yielded 0-0888 grm. of 

 cholesteride, equal to - 0635 per cent, free cholesterol. There was no ester 

 cholesterol. 



The lungs weighed 942 grm. Half the extract yielded 0-0962 grm. of 

 cholesteride, equal to 0-4863 per cent, free cholesterol. The saponified half 

 yielded 0-1084 grm., equal to 0'5593 per cent, total cholesterol, and, by 

 difference, - 0730 per cent, ester cholesterol. 



The brain weighed 10-63 grm. One-fourth of the extract yielded 0-3070 of 

 cholesteride, corresponding to 2'8796 per cent, free cholesterol. There was 

 no ester. 



Cholesterol Content of those Organs of Babbits fed on Bran which had been 

 Thoroughly Extracted with Ether to Bemove all Eat and Phytosterols, and, 

 of Babbits fed on the Same Diet with Added Cholesterol. 



Experiment IV : — 



A healthy doe rabbit fed on this diet for two weeks. Its weight remained 

 constant. 



The blood ; 74 - 7 grm. were taken. The unsaponified half yielded 

 0-0620 grm. of cholesteride, corresponding to - 0403 per cent, free cholesterol. 

 There was no ester. 



The kidneys weighed 12'675 grm. The unsaponified half -yielded 

 - 0925 grm. of cholesteride, corresponding to 0-3547 per cent, free chole- 

 sterol. The saponified half yielded 0*0943 grm. cholesteride, corresponding 

 to 0-3614 per cent, total cholesterol, and, by difference, 0"0067 per cent, ester 

 cholesterol. 



The muscle ; 100 grm. taken. The unsaponified half yielded 0-0900 grm. of 

 cholesteride, equal to 0-0437 per cent, free cholesterol. There was no ester. 



The lungs weighed 8*31 grm. The unsaponified half yielded 0-0937 grm. 

 of cholesteride, equal to 0-5481 per cent, free cholesterol. There was no 

 ester. 



The brain weighed 9 -84 grm. One-fifth of the unsaponified half yielded 

 - 1638 grm. of cholesteride, equal to 2-0225 per cent, free cholesterol. There 

 was no ester. 

 Experiment V: — 



A healthy rabbit was fed on the extracted bran with cholesterol. During 

 19 days it received 1480 grm. of bran and 4 - 8 grm. of cholesterol. There 

 was a loss in weight of 0'2 kgrm. 



The blood; 91 - 2 grm. were taken. The unsaponified half of the extract 

 yielded 0-1162 grm. of cholesteride, equal to 0-0619 per cent, free cholesterol. 

 There was no ester cholesterol.
