Sends a short résumé of his trip on the chance that it will arrive in England earlier than longer letter [158] which he hopes to send by surer means.

He is "incessantly occupied by new and most interesting animals" and thinks he will be able to do some original work in natural history.

Writes with great happiness about the first part of the voyage, after his misery from seasickness passed. He finds himself well prepared, the ship quiet, comfortable, and compact; he has already a "rich harvest" and finds the natural history (especially geology) exceedingly interesting. The tropics are full of great beauty.
