The voyage from London to Hamburg, which I performed in a steamer, lasted a day longer than ordinary, and was one of the most dreadful and annoying I have ever experienced. We were overtaken by a tempest, by which the vessel was tossed about in such a manner that all the passengers suffered from sea sickness. If I say that our feelings were those of a person whose bowels are being cut through with sharp knives, the comparison would remain far behind the real fact.

This remedy proved quite efficacious, and I was fortunate enough to be entirely recovered in the space of six hours.
As there are many substitutes for ipecacuanha, I think
