IMPETIGINES. 647 



" The mezereon has long had the reputation of curing ve- 

 nereal nodes, which mercury had failed to do. 



" It is likewise said to cure other remains of the venereal dis- 

 ease, which mercury, taken in large quantities had failed to do ; 

 and in one case of ulcerations in many different parts of the 

 body, which remained after mercury had been long and largely 

 employed, I have found them entirely cured by the use of the 

 decoction of mezereon for two or three weeks. 11 



MDCCLXXXVI. With regard to the many and various 

 preparations of mercury, I do not think it necessary to give any 

 enumeration of them here, as they are commonly very well 

 known, and have been lately well enumerated by Dr. Schwe- 

 diauer. The choice of them seems to be for the most part a 

 matter of indifference ; as I believe cures have been, and still 

 may be, effected by many different preparations, if properly ad- 

 ministered. The proper administration seems to consist, ls, 

 In the choosing those preparations which are the least ready to 

 run off by stool ; and therefore the applications externally by 

 unction are in many cases the most convenient. 2<%, In em- 

 ploying the unction, or in giving a preparation of mercury in-

 length, in the continuing the employment of mercury for sever- 

 al weeks, or till the symptoms of the disease shall have for some 

 time entirely disappeared. I say nothing of the regimen pro- 

 per and necessary for patients during the employment of mer- 

 cury, because I presume it to be very well known. 



MDCCLXXXVII. Amongst the other preparations of 

 mercury, I believe the corrosive sublimate has often been em- 

 ployed with advantage ; but I believe also that it requires be- 

 ing continued for a longer time than is necessary in the employ- 

 ment of other preparations in the manner above proposed, and 

 I suspect it has often failed in making a cure because employed 

 while persons were at the same time exposed to the free air. 



MDCCLXXXVIII. Upon these points, and others rela- 

 tive to the administration of mercury, and the cure of this dis- 

 ease, I might offer some particular remarks, but I believe they 

 are generally understood ; and it is enough for me to say here, 

 that if practitioners will attend, and patients will submit to the
