ResumoThis memoir contains a detailed account of an extensive series of observations made by the author during a residence of two years in the colony, and is accompanied with several maps, sections, and sketches illustrative of the islands, their conformation and structure. A collection also of the corals, shells, and rock-specimens referred to in the memoir have been presented to the Society by Capt. Nelson, and are arranged in the Society's Museum together with the Bermuda collection previously presented by him. The observations on the Bermudas, written during 1830-33, and printed in the Society's Transactions for 1837*, stand in such close relation, says the author, to those of the present communication, that the latter may be considered as a sequel to the former, justifying the surmise offered at p. 121 of the Bermuda Memoir† that it is "highly probable that the Bahamas were produced by the same causes as those to which the Bermudas owe their existence;" and showing that both groups are so far identical in character that they may be placed on the same fine in any geological system, as a peculiar post-tertiary formation of a composite character, not only of organic ‡ origin, but as Neptunian below and "Æolian§" above. Capt. Nelson has arranged the results of his observations on the Bahamas, as given in this memoir, as follows:— Part I. Descriptive Section 1. Geographical position and description of the different groups. 2. Occupation of the surface: topographically considered. 3. Construction of coral reefs. 4. Construction of
