    We have hitherto only confidered the more obvious effects of mercury; but its influence is extended over every part of the body. What particular action it excites in the bones, it is im- poflible for us toafcertain, where the parts are not expofed to our view. But we find where a bone or periofteum is thickened by a morbid poifon, that under the ufe of mercury it ufually firft foft- ens, and then recovers its foun. When an open ulcer exifts, we fee much the fame effe&s as on the foft parts, allowing'for the difference of ftru&ure. If the conftitution is under the influ- ence of a morbid pojfon, which has its crifis and termination, mercury feems, in fome inftances, to render the bones peculiarly fufceptible of the ir- ritation of the poifon. Moft of the accounts I have been able to collecl of yaws {how that if its progrefs is interrupted by a too early exhibition of mercury, the difeafe may be for a time diverted from the {kin, but that there is great danger of the bones at the fame time taking on a morbid difpo- fieioii. What effeft it has on the aBion induced by other poifons in the bones, has not beetf hitherto afcertained, excepting in the venereal. Hitherto we have confidered only the local aBions induced by mercury. But its effeas on the conftitution are not lefs deferving our attenti- on. The fever it produces may be truly called fpeci-
