Emetics

the only medicine used in that disease. I have not yet try'd that practice
Dr M_ has spoken highly of an emetic called the dry Vomit
which is composed of equal parts of Tart. Emet. and Blue Vitriol,
the dose is five grains without any liquid from which it is so called,
sometimes some of the preparations of mercury are emetic, principally
the saline ones, as Corosive Sublimate &c.

Turbith Mineral.
This acts briskly as an emetic in doses of of from 3 to 5 or 6 grains,
for an adult, it is usefull for this purpose in particular, but if a purge
be not given after it pukes it is apt to salivate. I employ it to produce
this effect, it is sometimes given in "Hernia Humoralis". Dr Cullen
does not like this preparation as an emetic but I have used it in various
affections. I have prescribed it in Cynanche Maligna and
Scarlatina Anginosa, with success, as an emetic, it appears to throw off an unusual
quantity of water from the stomach. I lately gave in "Cynanche Maligna"
grs 3 [3 grains] of it to a child 4 years old.

Sulphate of Zinc. Or White
Vitriol. This is a quick emetic in doses of from 5 to 6 grains, on this
account it is generally given when poisons has been taken into the stomach.
I prefer however the Ipecacuanha, or an infusion of mustard in those
cases. The Vitriolic Solution has been much praised by Dr Morely
his formula is as follows Rx Vit Alba. Ʒiij [3 drams] Rock Allum Ʒi [1 dram] Aq. Bullions lbi [1 pound]
