revived from the glafs, or calx antimonii, it refumes 
the fpiculine or needle-)ike appearance ; and when 
mercurius vhte is flux’d without any addition, it be- 
comes a fpiculine regulus, or a mere mafs of fuch 
aculei, or needles. 
Indeed it feems to be from this fpiculine or needle- 
like form (which is condantly retained by the mi- 
nuted: particles of the reguline fubdance), that an- 
timonial preparations have their emetic quality. Thus 
faline bodies dimulate by their points, or edges; fub- 
limate corioflve by its falts actuated by the weight 
of the cohering mercury ; arfenic by its rigid, flaarp- 
pointed, heavy particles. For when thefe reguline 
fpicula are fheath’d up in a large quantity of fulphur, 
as in the crude antimony, they exert no fuch power ; 
and if regulus of antimony is melted up with pretty 
much fulphur, it becomes quite as inert as the crude 
mineral. So regulus, or glafs of antimony, melted 
with wax, is rendered exceedingly much milder than 
before. Nay, even the virulent quality of the dronged 
white arfenic may be furprizingly taken off, by inti- 
mately uniting it with common fulphur by fuflon. 
It fhould feem then, that this fulphureous covering 
blunts or (heaths up the points of thefe acrid bodies, 
and takes off the irritation, which they would other- 
wife caufe on the nervous coats of the ffomach and 
guts. This is plainly feen in the glafs of antimony 
with melted wax; which, though in itfelf the moff: 
violent of all emetics, thus becomes infinitely more 
gentle, and may be given to adults from four, fix, or 
eight grains, to flxteen, with fafety, and great ad- 
vantage in fome cafes ; whereas two or three grains of 
the powder’d glafs will excite mod dreadful vomit- 
ings.
