When heated in a vacuum,it decomposes according to — 2(NH20H)3 P04=6NHoOH +HgO +H4Pg0r7. In an open vessel it decomposesat 148° into ammonia, water, phosphoric acid, nitrous acid, andammonium phosphate. Salts of hydroxylamine in anhydrous solution. None of the preceding experiments, from which doublesalts were obtained, were carried on in anhydrous solution, andthe object now, is to see if salts like copper sulphate will crys-tallize with hydroxylamine in absence of water. As the hydroxyla-mine was found to be more stable in methyl alcohol than in ethylalcohol, absolute methyl alcohol was used as the solvent. The abso-lute methyl alcohol after being boiled several days with calciumoxide, and allowed to stand several
