plest and least likel,v to irritate, but the stronger applications can 

 usually be borne. The Lassar paste consists of two parts each of 

 finely powdered talc and zinc oxide, four parts of vaseline and 

 three per cent, of .salicylic acid. Oxide of bismuth may sub.sti- 

 tute the zinc oxide. Three parts of olive oil aird four of diachy- 

 lon plaster melted together and stirred until cool, makes another 

 mildly astringent and sedative application. Iodoform i dr. to an 

 ounce of vaseline is an excellent agent. A mixture of iodoform and 

 tannin is used as a dusting powder by Friedberger and Frohner : 

 or silver nitrate solution (6:100) may beu.sed. Tar ointment (1:8) 

 with a little subcarbonate of potassium added makes an excellent 

 application. Oil of cade and oil of white birch may be u.sed in the 

 same way, the latter being the most desirable as a rule. Ammonia 

 chloride of mercury as an ointment { i : 10), often acts well and 

 the black wash, formed by the decomposition of calomel with 

 potash is often serviceable. Iodide of sulphur and vaseline ( i : 10) 

 is often an excellent resort. An ointment of equal parts of Can- 

 ada balsam and sulphur or iodide of sulphur in four parts of 

 vaseline is often effective. Other valuable preparations are 

 ointments (iC/r ) of iclithyol, naphthol, chrysarobin or pyrogallol. 

 Hebra's last resort of green soap is never to be forgotten, the 

 affected skin being thickly smeared with the soap which is left 

 to dry on, and is repeated and rubbed in, for several days in suc- 

 cession. It may seem at fir.st to aggravate the disea.se by reason 

 of the solution and removal of the covering of the vesicles or 

 pustules and the exposure of a pink sensitive surface, but day by 

 day this improves and the skin becomes smooth and more nat- 

 ural. After a few days of this treatment, it may, if necessary, be 

 followed by astringent or stimulant dressings, or the varied 

 medicaments may be incorporated with the soap .so as to form 

 one dressing to be applied from the first. When a healthy action 

 has been once established, all that is required further may be 

 cleanliness, with the use of bland dusting powders or ointments 

 to e.stablish the cure.
