The syrup of the sweet 

 principle weighed 8*2. 



All the soaps of stearine were analyzed by the same process as 

 the soap of the fat from which they had been extracted ; there 

 was procured from them the pearly super-margarate of potash 

 and the oleate ; but the first was much more abundant than the 

 second. The margaric acid of the stearines had precisely the 

 same capacity for saturation as that which was extracted from the 

 soaps formed of fat. The margaric acid of the stearine of the 

 sheep was fusible at 144°, and that of the stearine of the ox at 

 143-5°, while the margaric acids of the hog and the goose had 

 nearly the same fusibility with the margaric acid of the fat of these 

 animals. 



Of the Ela'ines. — They were all fusible at 59°; there was no 

 deposit from them after they had been kept for a month in closed 

 vessels ; none of them were acid. Human eldine is yellow, 

 without odour, specific gravity -913 ; eldine of the sheep is with- 

 out colour, has a slight smell of the sheep, specific gravity -916; 

 eldine of the ox, without colour, almost without odour, specific 

 gravity "913 ; eldine of the hog, without colour, almost without 

 odour, specific gravity -915 ; eldine of the jaguar, of a lemon 

 colour, odorous, specific gravity -914 ; eldine of the goose, of a 

 light lemon colour, almost without odour, specific gravity -92-9. 



Solubility of the different Ela'ines in Alcohol of '7952. 



Human eldine: 1T1 gr. were dissolved by 9 gr. of boiling 

 alcohol; the solution began to become opaque at 170-5°. 



Elaine of the sheep : 3*76 gr. were dissolved at the temperature 

 of 167° by 3-05 gr. of alcohol ; the fluid began to become opaque 

 at 145-5°. 



Elaine of the ox : 5'8 gr. were dissolved at the temperature of 

 167° by 4-7 gr. of alcohol ; the fluid began to become opaque at 

 145-5°. 



Elaine of the hog : ll'l gr. were dissolved at the temperature 

 of 167° by 9 gr. of alcohol ; the fluid began to become opaque 

 at 143-5°. 



Elaine of the jaguar : 3-35 gr. were dissolved at the temper- 

 ature of 167° by 2-71 gr. of alcohol ; the fluid began to become 

 opaque at 140°. 



Elaine of the goose : 11-1 gr. were dissolved at the temperature 

 of 167° by 9 gr. of alcohol, the solution did not become turbid 

 until 123-5.
