Stimulants

the experiments of others prove to the contrary, for the experiments
of Crump I refer you to his book on Opium, the theoretical part
of his work is excellent, but I differ from him in the practical
part. Opium has certainly removed spasms of the feet, by being
applied to the soles of them, Laudanum rubbed on the stomach
have removed obstinate spasm and vomiting. Dr Crump prefers
the solution and says it not only acts upon the part to which
it is applied but that its influence is manifest all over the whole
system, his observations on the external use of opium is worthy
the attention of every student of Medicine. Dr Jacksons
experiments go to prove that opium has no effect on the system when
externally applied, but from my own observations I can
unequivocally assert that when applied externally it produces the
most characteristic effects which follow its internal use. I saw
its deleterious effects on a woman by her rubbing it on another,
there are many other effects which I could advance in support
of this opinion, a woman in this City had for some time
had Laudenum rubbed on her temples which induced sleep,
costiveness &c. Sickness at stomach, mania &c, have
sometime been removed by rubbing large quantities of Laudanum
