60 ECONOMY OF FARMING. 



By Morin's analysis 100 parts contain : 



Water, ...... 70. 



Vegetable fibre, ..... 24.08 



Green resin and fat acids, . . . 1.52 



Undecomposed biliary matter, . . . 0.60 



Peculiar extractive matter, . . . 1-60 



Albumen, 0.40 



Biliary resin, ..... 1.80 



100.00 



Dr. Dana observes also that in 100 parts of cow-dung there are of 



Nitrogen, ...... .506 



Carbon, 201 



Hydrogen, ..... .824 



Oxygen, . . . . • .4.818 



So that 100 parts of fresh cow-dung will afford 0.614 or | of a pound of pure ammonia, 

 or about 2 lbs. 2 oz. of carbonate of ammonia of the shops. 



The urine of the cow, according to Brand, contains : 



Acid, salts, potash, and ammonia, . . = 0.015 



Sulphate of potash .... =0.006 



Carbonic acid, . . . . = 004 



Uric acid, =0.004 



Phosphate of lime, . • . . = 0.003 



0.032 



The urine of the horse, according to Fgdrcroy and VAuauELiN, contain : 

 Benzoic acid with natron or soda. . . 0.024 



Carbonic acid, 009 



Acetate of potash, .... 0.009 



Uric acid, 0.007 



Carbonate of lime, .... 0.011 



0.060 



According to Veit, also, the analysis of the dung of some of the domestic animalfi 

 furnishes us with the following result: 



a. The constituents of excrements, in a dry state. 



1. Juices of plants, with remains of food, 



2. A mud-like green powder, with coagulated albumen, and 

 bowel-slime, ...... 



3. Gall stuff, with extractive matter, 



4. Gall sugar with soluble salts, 



b. The ashes of the excrements, amount to 

 And contain, of silicious earth, phosphate and carbonate 



of hme, . . . . . . 



Carbonic acid, phosphoric acid, and acetate of natron . 



c. The absorption of the acids of the atmosphere, and the 



formation of carbonic acid gas corresponds to the pro- 

 portions, ...... 



d. Excrements in a moist state, contain of water. 



Of vegetable manures, there are a great variety in leaves, straw, weeds, ferns, pond- 

 mud, &c. &c., green plants, &c. So of mineral manures: sulphur, hme, potash, &c.
