Emetics

take up the matter contained in the bubo. Emetics have also been
employ’d in the bite of venimous reptiles and are verry usefull here.

Incarcerated Hernia. I have had no experience of their effects,
they probably act by exciting nausea, and thus relieve the spasm.
They are not commonly used as anthelmintics but worms are often
discharged by small doses. In Syngultus or Hiccough emetics have
been found usefull.

Particular Emetics. All the emetics are taken
from the vegitable or mineral kingdom. Dr Duncans division
of emetics is as follows, 1st Incitantia, as Turbith Mineral, Tartar
Emetic &c. 2nd Evacuantia. As Ipecacuanha, Squills &c. 3rd
Califacientia. As Horse Radish, Mustard seed &c. 4th Narcotica.
As Tobacco, Foxglove &c, But these do not act as emetics by their
Narcotic powers. I am not satisfied with Dr Duncans arangement
he has a class of Incitantia but they are all incitants, he has one
also of Evacuantia, but all emetics are evacuants. Professor Dobson
has made the following arrangement. 1st Relaxantia, 2nd Resolventia,
3rd Colida, Warm Emetics, 4th Drastica, Drastic Emetics. In my
own view of the subject I shall not follow any of their arangements,
But divide them into vegitable and mineral. First of the vegitable
emetics.

Nicotiana. Dr Cullen does not approve of
