Book excerpt: Excerpt from A Preliminary Report: On a Part of the Phosphates and Marls of Georgia Venezuela, Guiana and the coast of Africa, in the last decade, have furnished the European markets with considerable quantities of guano; but, as a result of the more humid condition of the atmosphere, under which it has been accumulated, it is usually inferior to the Peruvian deposits in ammonia, and, consequently, less valued as a fer tilizer. Previous to the introduction of guano into-europe, the chief com mercial fertilizers used, were animal charcoal and crushed bone, the only form of phosphates then known. On account of the insolubil ity of these manures, it was frequently necessary to use from one to two thousand pounds per acre, in order to obtain satisfactory results. During the year 1841, Dr. Liebig, the German chemist, discovered a process cf treating bones with sulphuric acid, which rendered the cal oium phosphate soluble. Bones, thus treated, were found, by experi ment, to have increased their fertilizing property more than fourfold. This important discovery was almost immediately followed by the erection of the first acid phosphate factory, in London, by J. B.
