The large mortality in croup and the inefficiency of remedial treatment have been the reasons why the recommendations of remedies have been very numerous. Alkalies were held in great favor during different periods of our literature, mainly the carbonate and bicarbonate of potassium (and sodium), in daily doses, to a child, of ½ drachm or 1 drachm or more; also the chlorate of potassium or sodium. As an adjuvant it may be useful; as an antidiphtheritic or antimembranous remedy it must not be regarded. What it can do is to heal or prevent a catarrhal stomatitis and pharyngitis. The best and most reliable is probably the iodide, in larger doses than are usually given. One or two drachms daily (grammes 4.0-8.0) are well tolerated when sufficiently diluted. Benzoate of sodium was recently recommended for its supposed antifermentative and antibacteric effect; its practical utility is but very limited; not even its antifebrile effect is anything but reliable. Lime-water has not fulfilled in my hands the promises made by others--neither its internal use nor spray nor inhalation. The most certain mode of introducing lime particles into the larynx is, after all, the inhalation of slaked lime, which allows a quantity sufficient to be somewhat effective to enter the respiratory organs. Its comparative inefficiency has been acknowledged by those who add 1 per cent. of the liquor of caustic potassium or sodium to the lime-water. Quinia, in doses of 15 or 30 grains (grammes 1.0-2.0) daily, has been recommended by Monti for the same indications, mainly in the commencement of febrile cases. It has been claimed that cold applications, to be changed every hour or two according to the Priessnitz or hydropathic plan, had a great power in macerating and disintegrating mucous membrane. Many of the successful cases of these, as of all other specialists, are undoubtedly the result of the convenient substitution of a grave diagnosis for a milder one. The effect of such applications in laryngeal catarrh, like that of warm applications, is undoubted. Vesicatories applied to the neck over the larynx are never {106} useful--frequently injurious by the sore surface becoming the seat of a pseudo-membrane. Inhalations of warm vapor are decidedly beneficial, but atomized water is not of equal value. Thus, Richardson's atomizer is not so useful as Siegle's inhaler or other apparatuses working on the same plan.
