folve more ful- nounced an i-ntention of examining the folvent power or the 



phurthanal- feveral ethers upon this combuftible: which I had at that 

 coho!-. . . 



iltne been prevented from, by being obliged to leave Paris 



for Brunblls, to take the office of apothecary to the military 

 hofpital. In the paper alluded to, I hinted that it was prob- 

 able ethers would diflblve fulphur in greater quantity than 

 alcohol ; I had been led into this opinion by the refults ob- 

 tained from mixing this mineral with alcohol^ at various de- 

 grees. I obferved, as already ftated, that the more alcohol 

 was re6!ified, the more readily it diflolved fulphur ; and vice- 

 Terfa, which differenGe I imagined to proceed from the 

 greater quantum of hydrogen contained in highly redified! 

 alcohol. Knowing ethers to contain lefs carbon and more 

 hydrogen than alcohol, I had no doubt that they would dif- 

 folve a greater quantity of fulphur. The refult of the fe- 

 veral experiments, which 1 made under this rmpreffion, I 

 am now about to detail : from which it will be perceived 

 that I was not miftaken in my conjecture. I Ihall alfo fub- 

 join the new experiments, which I made with alcohol, ta 

 afcertain the precife quanity of fulphur it is capable of dif- 

 folving, in order to compare the refults with th©fe obtained 

 from ethers. 

 Pireparationj &c. 'pjjg ethers I employed were prepared with much exafi- 

 nt'fs, and according to the methods recommended by pro- 

 feifor TfturGroy. 1 took care, in each experiment, to afcer- 

 tain the fpecific gravity of the ether made ufe of, the quan- 

 tity of fulphur difiblved by it, the various refults obtained 

 with or without the contad of the fun's rays, and the pro- 

 perties of fulphuraled ether.
