worms ; but it niuft be allowed to be a very uncer- 
tain medicine, and perhaps dangerous, as it may con- 
tain too fmall or too great a quantity of the fait of 
tin. 
If fait of tin be good for worms, it would be right 
to afcertain its dofe, and give it in a proper vehicle. 
I'm combined with Sulphur^ by Fujion. 
Four ounces of tin melted and faturated with 
fulphur weighed 5 5, and formed a black (Lining 
flaky brittle fubdance when melted. The tin need 
not be made quite red hot for this operation ; for, 
when the fulphur is mixed with it, a deflagration 
enfues, and the mixture grows red hot. In order to 
fatiirate the tin with as much fulphur as poflible, it 
mud: be added to it at two or three different times. 
The tin, notwithflanding, cannot be, by this means, 
perfedly faturated with fulphur j for after powdering 
and fifting it, there remains in the fieve a portion of 
the tin, which will flat under the peftle, and not 
powder any more, unlefs melted and combined with 
more fulphur. If this operation be done with too 
great a degree of fire, the increafe of weight will not 
be fo confiderable, on account of the great fire, which 
diflipates fome of the fulphur. 
Four ounces of Aurum mofaicum melted in a 
covered crucible lofes 56 of its weight, and becomes 
a mafs fomewhat like melted fulphurated tin, though 
it be not fo fhining, nor fo flaky, but rather more of 
a needle form. If the fufion be repeated two or 
three times, fome of its fulphur will be each time 
diffipated, and have exadly tlie appearance of ful- 
phurated tin.
