surface. For the tonsils, undiluted hydrochloric acid is to be 

 used ; but for any other part of the soft palate solid nitrate of 

 silver. This latter caustic is to be applied to those excoriations 

 which may appear about this time. These potent escharotics 

 cannot be used again, until at least four or five days have 

 elapsed. The external swelling should be assiduously fomented, 

 and poultices may be continued. 



All cases of otorrhoea are to be treated by syringing the 

 meatus gently with warm water three or four times a day. 

 Should a discharge either from the ear or from the nose become 

 chronic, quinine and sulphuric acid may be tried. If there is a 

 suppurative tendency, quinine will also be found useful ; also 

 substantial food will be required. 



As a rule rheumatism, if it be present, rapidly subsides under 

 the influence of salicylate oi sodium. Aperients, if necessary, 

 may be administered, and cotton-wool or poultices may be put 

 round the affected joints. 



At the onset of renal dropsy, purgatives must be given ; 

 for instance, a good jalap powder in doses of not less than a 

 scruple to a child of six or eight years of age, repeated at 

 intervals of eight hours, until the bowels act freely. 



The hot-air bath, preceded by a hot-water bath and a dose 

 of antimonial wine, may be used every uight, so long as the 

 quantity of urine is much diminished. Vomiting may be in 

 some degree checked by ice swallowed in small lumps. When 

 there is much hsematuria, gallic acid may be tried. Quinine 

 does good in some cases, and perchloride of iron is useful in 

 later stages. Counter-irritation to the loins will be useful, and 

 a milk diet is essential. 



When extensive anasarca is present, and especially if the 

 dropsy tends to the lungs and pleural sacs, the danger is very 

 grave indeed. Laxatives and diuretics should be continued, so 

 long as the anasarca remains simple. 



Complications must be treated in much the same manner 

 as if they occurred in the general way, but it should be remem- 

 bered that patients bear depletion less and need stimulation 

 more. To these general lines of treatment we may add, as 

 another point of very great importance, that those who are 

 convalescing from attacks of scarlet fever may often be very 

 greatly benefited by a change of air. It is especially the won-
