which ftrongly attracting the alcaline fait, the ful- 
phureous and reguline parts foon fall to the bottom. 
Nor are thefe latter very firmly united, as the alca- 
lious fait did, during the flux, in fome meafure de- 
tach the antimonial fulphur from the reguline parts. 
It is evident the cohefion is but loofe $ other wife fo 
great a proportion of fulphur, as is found in the ful- 
phur auratum, would, if very intimately combined 
with the reguline parts, have fo fheathed up thefe 
fpicula, as to render them incapable of imprefling 
any great irritation on the coats of the ftomach, &c. 
as is feen in crude antimony, and its regeneration 
from fulphur and regulus. Befides, though the firfl 
precipitation of the fulphur auratum is greatly im- 
pregnated with reguline parts, yet the fecond or third 
precipitation holds exceedingly few, and is almoft in- 
tirely fulphureous, and fcarce at all emetic. If you 
would have this milder, or more light fulphur, you 
fhould not pour on too much of the precipitating 
acid at firfl: ; or rather fluffier the antimonial lixivium 
or folution to hand, for fome days, expofed in a cold 
open air ; for thus the impure reguline fulphur will 
fall of itfelf ; after which you may inftill the acid 
as uTual- and, if you do thus, by gentle degrees, in 
fmall quantities, after the fecond or third precipitation, 
the fulphur will fall almoft pure; which fhews, that 
the fulphur in the hepatic folution is not very clofely 
united with the regulus. By the way, however, as 
the antimonial lixivium, from the hepar, is fo fully 
fraught with reguline particles, and thefe fo much 
unfheathed, it is conftantly more or lefs emetic, not- 
withftanding what Monfieur Lemery afisrts to the 
contrary. But that is not the only exceptionable 
thing
