Huxley's position in the field of science -- the fame of the scientific investigations of the HMS Rattlesnake -- should insure a small but dependable sale for this diary -- or one should say, extracts from four diaries. Four voyages in in all, and Huxley serving as assistant surgeon, and research director of certain phases of marine natural history. The first diary is too strictly scientific for the average reader; from the time he meets and falls in love with the Australian girl who eventually became his wife, the text gathers momentum and interest.
