SOLUTION OP SULPHUR IN ALCOHOL, ni 



fained 16 grains from the firft mixture, and 13 from the ie- 

 cond. 



After what has here been laid down, it is evident that ful- Recapitulation. 

 phuric ether diHolved the greateft quantity of fulphur ; for, 

 after frequently repeating the experiment, I found the avc- 

 rage to be 25 grains in an ounce. Nitric ether and alcohol 

 at -1-3 degrees, diflblved nearly in the fame proportions ; and 

 acetic ether the lead of any. 



It has been long a defideratum in medicine to difcover a Sulphurated 

 method o( adminiftering fulphur in a ftate of extreme divi- ^^^^5 .'^^ 2°"'* 

 lion, efpecially in complaints of the lungs and difeafes of the 

 fkin. With this intent, ph}'licians hax'e recommended it to 

 be dinbived in eflential oils, and to form what is known in 

 pharmacy under the title of balfams of fulphur, terebinthinated, 

 anifiited, S^c. Thefe medicaments have the difadvantage of 

 giving to the mixtures into which tliey enter an almoltin- 

 fupportable tafte and fmell of fulphurated hydrogen. Sul- 

 phurated etlier is free from this inconvenience ; it may be 

 eafily mixed with other potions, to which it gives very little 

 fmell ; and as the feparation of the fulphur is only occa- 

 fioned by the evaporation of the ether, it may be eafily pre- 

 vented by keeping the mixture to which it is added clofely 

 corked. I have already adopted its ufe with fuccefs, ad- - 



jniniflered either upon fugar, or with any appropriate ve- 

 hicle : feveral phylicLans of my acquaintance, for whom I 

 have prepared it, have likewlfe employed it with advan- 

 tage ; and I hope, ere long, to be able to flatter myfelf 

 as having added an efficacious medicament to the art of 

 healing.

in addition to the facility with which this ether precipitates 



the lead, jn the form of a black fulphur, it polfelTes the ad- 

 vantage of introducing nothing into the wine that can de- 

 ceive as to its quality, which fometimes happens even to 

 thofe who are accuftomed to ufe the folution of fulphur of 

 potafii. 



I am now occupied in the cryftallization of fulphur dif-
