consisting in the free use of emetics or purgatives, has been recommended by some eminent practitioners. Withering,[9] Tissot, Kennedy and others are in favor of the former, and find fault with the latter, whilst Hamilton,[10] Willard, Abernethy, Gregory, &c., prefer purgatives, and some, of course, look upon calomel as the anchor of safety, which they recommend in quantities of from five to ten grains per hour.[11] The friends of one part of the anti-gastric method make war upon the other: Withering finding purgatives entirely out of place and Sandwith, Fothergill and others having seen nothing but harm done by them, whilst Wendt,[12] Berndt,[13] Heyfelder and others caution their readers against emetics. The anti-gastric method has been of some service in epidemics and individual cases, when the character of the disease was decidedly gastric and bilious. To use emetics or purgatives indiscriminately would do much more harm than good; as, for instance, during a congestive condition of the brain, the former, and with inflammatory symptoms of the bowels, the latter, would be almost sure to sacrifice the patient to the method. 36. THE AMMONIUM CARBONICUM, recommended by Peart,[14] has been considered by many as a specific capable of neutralizing the scarlatinous poison, whilst others have used it only as a powerful tonic in torpid cases. Experience has shown that it is not a specific, and that its use as a tonic, requiring a great deal of care and discrimination, is a good deal more dangerous than the mode of treatment I am going to recommend in cases where tonics are required. 37. CHLORIDE OF LIME. About the same opinion may be given on _Chloride of Lime_. As a gargle, and taken internally, the aqua-chlorina has done good service in malignant scarlatina, especially in putrid cases. 38. ACETIC ACID. Brown[15] recommends diluted _Acetic Acid_ as a specific against all forms of scarlatina. Experience, however, has not supported his confidence in the infallibility of his remedy. 39. MINERAL ACIDS (MURIATIC ACID--PRESCRIPTIONS) have also been used with good effect in some epidemics. _Muriatic acid_ I have frequently used myself for inflammation of the throat, in connection with hydriatic treatment, and it has almost always contributed to relieve the symptoms materially.[16] 40.
