This last experiment most nearly represents the true power of absorption; because, in fermenting manures, ammonia mostly occurs in the form of carbonate, and this is more largely retained than free ammonia, on account of its power of decomposing the Humate of lime, forming with it carbonate of lime and Humate of ammonia.

This compound, in most cases, has been formed in the burning, from Humate and other organic salts of lime.
