This is a very distressing affection, and one that some people are very subject to; others again can make a long voyage without the slightest inconvenience; and children generally suffer less than grown people. Some people, no matter how much time they spend at sea, never outgrow the susceptibility, but, as soon as rough weather comes on, they become sick. Lying flat on the back, and shutting the eyes, is often beneficial. Some people find taking a stimulant, as brandy, a preventive. For my own part, I have found that eating pickles, when at sea, had more effect in keeping off sea-sickness than any other remedy. A writer in the "British Medical Journal" suggestsHydrate of Chloral as a certain remedy, by its sending the passenger to sleep. Some cases published by Dr. Doring of Vienna, seem to show that the value of Hydrate of Chloral to obviate sea-sickness is very great. It produces quiet and prolonged sleep. In all the instances recorded, it seems to have been of great value, even during prolonged sea-voyages; giving a good night's rest, arresting violent sickness when it had set in, and stopping a tendency to its recurrence.
