LIQUID PARTS OF ANIMALS. 



tion of it was filtered and distilled over the steam-bath. The 

 liquid that passed into the receiver contained acetate of ammonia. 

 When the liquor of sweat was evaporated to dryness it left 

 from a half to one and a-quarter per cent, of dry residue. This 

 residue being treated with alcohol of 0-833, a portion remained 

 undissolved. When the alcoholic solution was evaporated to dry- 

 ness there remained an extractive matter mixed with a great 

 number of saline crystals. From this matter absolute alcohol 

 separated an acid extractive substance, containing, according to 

 Anselmino, acetic acid, acetate of potash, and an animal matter 

 precipitable by infusion of nut-galls. The portion of matter in- 

 soluble in absolute alcohol consisted of common salt with a little 

 chloride of potassium, and an animal substance not precipitable 

 by chlorine, chloride of tin, nor corrosive sublimate. 



The portion of dried sweat left by alcohol is almost all solu- 

 ble in warm water, a little deep-gray powder only remaining. 

 It seems to be a mixture of epidermis and phosphate of lime. 

 When burnt it leaves a bulky ash, consisting of phosphate of 

 lime, mixed with a small quantity of carbonate of lime. The 

 portion dissolved in the warm water contains sulphates, and an 

 animal matter precipitated by chloride of tin, and by infusion of 

 nut-galls. Chlorine occasions no immediate precipitate ; but in 

 twenty-four hours white flocks separate from the liquid. 



According to the analysis of Anselmino 100 parts of the dry 

 residue from sweat are composed as follows : 

 Matters insoluble in water and alcohol, 1 

 (mostly salts of lime,) . J 



Animal matter soluble in water, and not 1 

 in alcohol, with sulphates, / 



Matters soluble in weak alcohol, com- 1 

 mon salt, and animal extract, / 



Matters soluble in absolute alcohol, ani- 

 mal extract, lactic acid and lactates, 



100 



Anselmino found, likewise, that 100 parts of the dry residue of 

 sweat when burnt leave 22'9 of ashes, containing carbonate, 

 sulphate, and phosphate of soda ; a little of the same acids com- 

 bined with potash and common salt, all soluble in water. Be-
