Its advantageous effects are well demonstrated in sordid and eroding ulcers, and in certain cutaneous affections resembling those which the ancients called lupus and noli me tangere, 22, 2: 172.

Its employment is not confined to cutaneous affections of one particular elementary form, since it is given with good effect in papular, vesicular, pustular, and tubercular skin diseases of a chronic kind when they occur in enfeebled and emaciated constitutions, 7, 367.

Its efficacy is well established, and its mode of action, though obscure, is generally attributed to a purifying influence on the blood, through the function of the skin, 11, 271.

"It will commonly relieve, in a very short space of time, venereal headaches and nocturnal pains; and, if persisted in, I believe, will always cure.

"In emaciated or consumptive habits from a venereal cause, it is the greatest restorer of appetite, flesh, color, strength and vigor that I know of.

"When the throat, nose, palate, or the spongy bones in general, are affected with a slough or caries, it will commonly complete the cure, if persevered in long enough, provided a mercurial course, I mean by unction, has preceded the use of sarsaparilla.

"When the body is covered with dry blotches or moist sores (still supposing the cause venereal), it will greatly promote the cure, ay, often complete it; but, without the assistance of mercury, there will be danger of relapse.

"In simple chancres it will do little service; but if it is given in cases where the chancres and buboes will not heal or dissolve after the use of mercurial unction, it will often cure, and always do manifest service.

"It would seem probable, from any observations I have yet been able to make, that the sarsaparilla is only to be depended on in venereal cases where mercury has failed; at least, has preceded the use of the decoction, or when it is combined with it, and then is not to be trusted alone, unless in such circumstances.

"And this is agreeable to the well-known effects of that medicine, the reputation of which, in inveterate venereal cases, first put me in making this inquiry." Fordyce.*
