it often pukes, and purges gently, if given to ten or 
fifteen grains, efpecially on the firft ufe of it. 
It appears then, from what hath been faid above, 
that fulphur auratum, kermes mineral, Ruffel’s pow- 
der, or Wilfon’s panacea of antimony without fire, 
are all of the fame nature, though indeed fomewhat 
different in their ftrength, and pretty uncertain in 
their operation ; and therefore require a careful hand 
to prepare, and a good head to adminifler them with 
advantage. For the reguline principle will be much 
more predominant in the fcoriae of the very fame 
kind of regulus of antimony, if it is kept for a long 
time in a brifk fire, than it would be, if for a much 
fhorter time ; not to mention what I have faid be- 
fore, as to the manner of precipitating, &c. the ful- 
phur auratum. And kermes mineral differs not a 
little, as prepared with a ftronger or weaker lixi- 
vium, as more or lefs carefully wafhed and edulco- 
rated, and as fpirit of wine is, or is not, at lafl de- 
flagrated with it. Whoever would give them, fhould 
begin with fmall dofes, as a grain or two ; but, as he 
finds they agree, may gradually increafe to eight 
or ten, efpecially if they are intimately incorporated 
with any refinous extradt, natural balfam, or the 
like. But the dofes fhould by no means too quickly 
lucceed one the other ; for folid antimonials may lie 
a confiderable time in the body without any fenfible 
effedt, and yet, at length, operate all on a fudden, 
with exceeding great violence; particularly when 
wine, cyder, or any vegetable acid, are fwallowed 
upon them. 
Though common fait, fluxed with antimony, 
feems to do little more than promote its fufion,
