As regards the doses of these agents required in acute rheumatic arthritis, practitioners are not agreed; Maclagan, Stricker, Fagge, Broadbent, Ringer, Flint, Sée, recommend large doses at short intervals at the outset, with the view of getting the patient rapidly under the influence of the drug. Maclagan gives salicine scruple i-ij at first hourly, then every two hours as the acute symptoms begin to decline; after the second day he allows 20 to 30 grs. every four hours for two or three days; "and for a week or ten days more that quantity should be taken three times a day." Stricker, Fagge, Broadbent, and Sée recommend about 20 to 30 grs. of salicylate of sodium every hour or two for six doses (= drachm ij-iij in the day), and Ringer would employ 10 grs. hourly, and if in twenty-four hours this dose has not either modified the disease or produced its characteristic symptoms, he would increase it to 15 and then to 20 grains hourly. On the other hand, Owen's180 results show practically no difference in the duration of pain and pyrexia and in the average duration of illness from the commencement, whether drachm iij or drachm ij or drachm iss were given every twenty-four hours; and C. G. Young181 found that 10 to 15 grs. every one, two, or three hours are sufficient.

Indeed, exceptionally good and exceptionally indifferent results are reported under similar doses. No such good results are reported as those of the Boston City Hospital under doses of drachm ij to drachm iv per diem, the average residence in hospital being only eighteen days if four cases which became chronic are excluded, or 21.9 days if they are included.
The plan in vogue at our hospital here and in my own private practice is to give about 15 grains every two or three hours, according to the severity of the case and until the articular pain and pyrexia are relieved. After the pain and pyrexia have yielded, the remedy should be continued in smaller doses, say 10 to 15 grs., three or four times a day, according to the severity of the case, for eight to ten days longer, to prevent relapse, and during this period exposure, exercise, and dietetic excesses must be carefully guarded against.
The salicine may be given dissolved in milk or enclosed in wafers; the salicylate of soda, in a solution of any aromatic water, to which extract of liquorice or syrup of lemon and a few drops of spirits of chloroform may be added. The French add a little rum to flavor the mixture. Should severe cardiac inflammation exist, and, even although not severe, should there exist signs of failure of cardiac power, salicylates and salicine had better be avoided. If the secretion of urine diminish considerably under their use, or hæmaturia supervene, or organic disease of the kidneys exist, they must be employed cautiously, and may require prompt suspension. If marked debility exist, stimulants, especially the alcoholic, should be combined with them.
The oil of wintergreen has recently been well spoken of by F. P. Kinnicutt of St. Luke's Hospital, New York,182 as a substitute for salicylate sodium. It is itself a methyl salicylate 90 per cent., plus terebene 10 per cent. Its officinal name is oleum gaultheria, and it is given in doses of minim x-xv every two hours except during sleep, and in severe cases of articular rheumatism during the twenty-four hours, either by floating the oil upon a wineglass of water or milk or in capsules or upon lumps of white sugar. It resembles in its influence upon acute rheumatism very closely the sodium salicylate, for which it may perhaps be substituted, and Kinnicutt maintains that it is quite as effectual, pleasanter to take, and free from the intoxicating properties of the salt and the salicylic acid. It requires to be continued during convalescence just like the salicylate.
