_c._ In the form of Poultice.—RICE POULTICE.—To prepare this, place a sufficiency of Rice Flour in an open vessel over the fire, gradually add Water, and stir until the mass has the required consistence. A more ready mode is to place the Rice Flour in a basin, and then gradually to add Boiling Water, constantly stirring it, as above. A piece of cloth of the required size being ready at hand, the poultice should be smoothly spread on it, to the thickness of from a quarter to half an inch, and applied over the affected part. In most cases it is advisable before applying it, to smear the surface of the poultice with a bland oil; this renders it more soothing and keeps it longer soft and moist. A rice poultice requires changing twice or even thrice daily. It is an excellent application to _Abscesses_, _Boils_, _Buboes_, _Ulcers_, and _other local inflammatory affections_, _Inflamed Piles_, _&c._ _In Chronic Bronchitis and other Chronic Coughs_ considerable relief often results from the application of a large soft Rice Poultice placed over the chest at bedtime, and allowed to remain on all night; another may also be advantageously placed on the back between the shoulder-blades. The efficacy of these poultices is in many cases increased by the addition of a little Mustard Flour (1 part to 3 or 4 of Rice Flour), so as to produce a slight redness of the skin; or the surface of the poultice may be smeared over with Oil of Turpentine. 323. +Sal Ammoniac.+ Hydrochlorate of Ammonia, Chloride of Ammonium.

Sal Ammoniac, procurable in most Indian bazaars, is generally very impure; occurring in thick translucent cakes or masses of a dirty white or brownish colour, inodorous, of a bitter, acrid taste. To fit it for medical use, it should be dissolved in boiling water, strained through calico, and the clear solution exposed in an open vessel to crystallise. The crystals and white residuum should be collected and kept in bottles for use. Thus prepared, it proves valuable in many affections. Its nauseous taste, which is a great objection to its use, is completely covered by the addition of a small quantity of liquorice. 325. _Milk Abscesses_ occurring after confinements and in nursing mothers may often be arrested, if at an early stage, before matter forms, the breast be kept constantly wet by means of rags saturated with a lotion composed of one drachm of Sal Ammoniac, one ounce of _Arrack_, and a pint of Rose Water. It also proves useful in removing any hardness which may remain after the abscess has burst, and is sometimes successful in arresting _Abscesses in other parts of the body_, when applied at an early stage before matter has formed.
