2-22 On the Germination and Fermentation 



When cleaned completely by means of water, the akins 

 of these lentils macerated in alcohol gave it a fine yellowish 

 oreen colour ; spontaneously evaporated, this alcohol depo- 

 sited green flakes and a crust of the same colour; it black- 

 ened the solution of iron. After this double treatment, 

 these skins are dry and arid. They furnished upon distilla- 

 tion a o-ood deal of oil, the smell and taste of which resem- 

 bled tobacco smoke ; the water of the distillation is acid, 

 but yields ammonia by means of potash. Thus, besides 

 their feculent matter, lentils contain a kind of albumen and 

 a little even oil : their bark contains tannin and more oil. 



§ VI. Analysis of the Farina of Lupines. 



1st, This farina is yellow and very bitter; when exposed 

 to the fire, it exhales an animal odour. 



2d Distilled in a retort it yields three-twelfths of charcoal^ 

 nearlv seven -twelfths of a foetid red oil, a twelfth of phlegm, 

 and a twelfth of crystallized carbonate of ammonia. The 

 •water contains a little ammoniacal acetate. We find in the 

 charcoal phosphate of potash, because its watery ley precipi- 

 tates calcareous phosphate by the addition of lime water. 

 We also find in the ashes of the burned farina of lupines, 

 phosphates of lime, magnesia, andiron. 



3d, It colours alcohol yellow, and renders it bitter; the 

 latter, spontaneously evaporated, leaves a yellow, thick, and 

 verv bitter oil, forming a-scventh of the weight of the farina, 

 which almost entirely dissipates upon burning coals, with 

 the smell of fat oil. 



4th, The farina of lupines gives water a yellow colour, a 

 bitter taste, and a frothy quality, without rendering it either 

 acid or alkaline. This water precipitates white flakes by the 

 oxymuriatic acid; a purple coagulum by infusion of galls*; 

 very abundant white (lakes by the nitrates of mercury and 

 silver, and the acetate of lead: there are a few muriates, not 

 soluble by the nitric acid, in the latter precipitates. It 

 yields also yellowish flakes by means of lime water, and a 

 white powder of calcareous oxalate by means of the ammo- 

 niacal oxalate. 



* M. Vatiq-ulin attributes this coIo»r to a little phosphate of iron.
