![capable of producing both effects, which differ in degree only, we have included them under the one title. Obstructed perspiration, or diseases in which diaphoresis will prove useful, may be associated with fever and inflammation, or may occur with a slow languid circulation ; the former is indicated by the morbid heat of the surface of the body, and by increased vascular action ; the latter by the coldness of the surface, and by general depression of the circulation. It is evident, therefore, that very different remedies will act as diaphoretics in these opposite states of the system. In the former case, those medicines are to be selected for use, which appear to act by relaxing the morbid constric- tion of the cutaneous capillaries, and at the same time have a direct tendency to lower the action of the heart and arteries ; such as anti- monials, and the alkaline and saline diaphoretics. In the latter, those remedies are to be employed, which act as stimulants to the cutaneous capillaries, and at the same time increase the general action of the vascular system. In addition to the medicines described in this division, other means are resorted to for the production of diaphoresis; the more important of these are increased muscular action, warm water and warm vapour or air baths, the cold affusion, and the use of tepid diluent drinks as simple water, gruel, whey, &c. During the adminis- tration of diaphoretics, it is essential, that the surface of the body should be kept warm, and for this purpose a bad conductor of heat, such as flannel, should be employed ; care also must be taken to avoid the application of cold, either by exposing the surface of the body to cold air, or by the use of cold drinks while the perspiration continues, or for some time after it has ceased ; lastly, where it is wished to check the diaphoresis, this must be done gradually, by drying the sur- face of the body with dry, warm towels, by diminishing the covering, and by cautiously exposing the hands and arms to the air. Ammonije acetatis aqua, D. E. Ammonite acetatis liquor, L. [XL S.]—Solution of acetate of ammonia; Mindererus Spirit. Preparation.—Dub.—Carbonate of ammonia, one part; add by de- grees, frequently agitating, sufficient warm distilled vinegar to saturate the ammonia, that is about 30 parts; this may be determined by means of litmus paper. Lond.— Sesquicarbonate of ammonia, §ivss., or a sufficiency ; distilled vinegar, Oiv.; add the salt to the vinegar to saturation. Edin.— Distilled vinegar, from French vinegar in preference, fgxxiv.; carbonate of ammonia, §i.; mix and dissolve the salt; if the solution has any bitter- ness, add by degrees a little distilled vinegar,till that taste be removed; the density of the distilled vinegar should be 1005, and that of the aqua acetatis ammonia?, 1011. [U. S. Diluted acetic acid, Oij. ; carbonate of ammo- nia, in powder, q. s. Add the carbonate of ammonia gradually to the acid until it is saturated.] Physical Properties.—A transparent colourless liquid, with a very faint odour, and a cooling saline taste. The specific gravity varies with the strength of the solution, that of the Dublin and Edinburgh is 1011 ; that of London somewhat higher. Chemical Properties.—It consists of acetate of ammonia dissolved in water, the proportion of the acetate present varies exceedingly, de- pending on the strength of the distilled vinegar employed in the pre-](https://iiif.wellcomecollection.org/image/b21143602_0144.jp2/full/800%2C/0/default.jpg)
