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.
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.
