Then measure out 10 c. C. ( = '7 gram of sample), and treat according to the method given under " Special Manures " (8) (a). (13) SULPHATE OF AMMONIA is the only ammoniacal salt used by the agriculturist. The ammonia is determined, as in guanos, in 2 grams of the 10 146 BONE PRODUCTS AND MANURES sample, by distillation with milk of magnesia, into a measured solution of decinormal acid, and then retitrated with deci- normal soda, and from the resulting c. C. , the ammonia and its equivalent as s...ulphate, calculated. Note. It may here be remarked that the methods described in the preceding pages are sufficient for all commercial purposes ; the buyer requires no more, and neither does the seller; and, however interesting a full analysis may be from a scientific standpoint, the works chemist is but seldom called on to carry it out.
