extraneous fossils which that splendid museum originally contained. It will be also seen from many of our pages that through the kindness of the late worthy President of the Royal Society, Sir Joseph Banks, the rich and truly scientific collection of that munificent patron of the sciences was ever open to us for the furtherance of our pursuits in Natural History; and of the object of the present work among others. The collections of Mr. Drury, and also that of Mr. Francillon, in the particular branches of Entomology, are too considerable to be passed slightly over: the rarities of both these collections have in an eminent degree improved our means of rendering this work important. And lastly we may mention among other scientific acquisitions the Collectanea of drawings formed by the pencil of the late Mr. Jones of Chelsea, together with the manuscripts of Fabricius in elucidation, as a treasure which cannot be too highly appreciated when we recollect the importance of the Fabrician writings on the continent, and remember also that those drawings afford the only illustration of the most splendid portion of the insect race which that author exclusively describes, and by which very many of the species can alone be now determined. In conclusion of these remarks it may be observed, however, that while in our elucidation of those rarities which the collections and museums above adverted to have so amply afforded, we render a deserved tribute of record to the liberality of those whose services in the cause of Natural History have so amply contributed to its advancement in former days, the author will not remain unmindful of those advantages which the many valuable collections of the present period offer. It will appear as this work proceeds that he is in no small degree indebted to the favor of many eminent scientific characters of our time, as well as those who have preceded them, for their permission to take drawings and descriptions of such rarities in their collections as really appear worthy of distinct consideration. And it may be added finally that he shall at all times avail himself with pleasure, and acknowledge with thanks, any further advantages of the same kind which the favours of others may be induced to allow for the purpose of enriching the present undertaking.
