Dose--hairs fluidrachm to two fluidrachms in infusion of linseed. Hydrargyri Submurias. Submuriate of Mercu-ry. Take of Purified mercury, by weight, four pounds, -Sulphuric acid, by weight, thirty ounces, ' uriate of soda a pound and a half, Muriate of ammonia eight ounces; Boil two pounds of the mercury with the sulphuric acid in a glass vessel, until the sulphate of mercur is dry; when this is cold triturate it with two-"pounds ofy mercury in an earthen mortar, that they may be thoroughly mixed. hen add the muriate of soda, and rub them together, until globules are no longer visible; afterwards sublime. Reduce the sublimed matter to a very fine powder, pass it through a sieve, and mix it carefully with the muriate of iiminonia previously dissolved in a gallon of boilino distiled " ' water. Set it by that the powder may subside. fine powder, in the same manner as that which we have directed in the preparation of chalk.
