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 shghtly 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.
