Hydrochlorate of Ammonia.

Dose.—From five to thirty grains.

Therapeutic Action.—This salt is a mild stimulant, resolvent and alterative, and is employed by continental physicians to fulfill these indications. It is used advantageously in the milder forms of pneumonia and bronchitis, in inflammations of serous membranes, pertussis, mucous diarrhoea, passive dropsies, chronic rheumatism and gout. Neligan states that he has found it useful as a stimulant in some forms of adynamic fevers, and also in sub-acute laryngitis. Mr. Class employed it extensively in the early stages of tubercular phthisis, and, he states, with the most decided beneficial results. We have employed it only in pertussis, in conjunction with belladonna, and in this disease we consider it decidedly beneficial.

Mr. Walker found that five parts each of this salt and nitrate of potash, dissolved in sixteen ounces of water, formed a refrigerant mixture, which reduced the temperature forty degrees. This mixture may be employed in any ease where an external refrigerant is indurated.
