MUSTARD CATAPLASM.

Take of mustard-seed, powdered, ½ lb.

crumb of bread, ½ do.

vinegar, as much as is sufficient.

Mix, and make a cataplasm.

Cataplasms of this kind are employed as _stimulants_: they

often inflame the part, and raise _blisters_, but not so

perfectly as cautharides. They are frequently applied to the

soles of the feet, in the low state of acute diseases, for

_raising the pulse_ and relieving the head.
