COLLECTIONS OF INSECTS AND OTHER SUBJECTS OF 

 NATURAL HISTORY, 



In order to facilitate the study of Natural History, especially those 

 departments most suitable for young persons, it is my intention to 

 form several small collections of Insects, Shells, 4c- Each Collec- 

 tion will have an accompanying catalogue of the generic and spe- 

 cific names, with reference to authors by whom the species are de- 

 scribed. Single specimens may also be obtained to illustrate genera, 

 as well as to assist those who may be forming collections. Also 

 every kind of apparatus used by the Botanist, Conchologist, Entomo- 

 logist, or Mineralogist ; such as collecting and other boxes, nets, for- 

 ceps, setting-boards, pins, pocket microscopes or hand magnifiers, ca- 

 binets, trays for minerals, shells. &cc. either corked or plain. Dissec- 

 tions of insects to illustrate their generic characters, or as most inter- 

 esting objects for the microscope. 



Mr. Sowerby intends also to re-open his very valuable and extensive 

 Museum, for the use of his friends and for the benefit of students and 

 lovers of natural history. The maiiy rare and interesting specimens 

 which this collection contains are highly deserving the honour which 

 it has received from many of the most distinguished personages. The 

 abilities and industry of its possessor are sufficiently known through 

 the medium of his voluminous scientific and useful works. This gen- 

 tleman has also been induced to offer for sale his duplicate specimens, 

 which consist of subjects in every department of Natural History. 

 These of themselves would form no mean Museum. However, he in- 

 tends to dispose of them in small parcels to give the student an insight 

 into the science, or in single specimens for the accommodation of those 

 who may already possess collections, and to whom such species may be 

 cksidc?'ata. 



Those ladies and gentlemen who reside in the country may have 

 collections, or any of the apparatus sent them, through the medium of 

 their booksellers, by an application to Mr. Boys the publisher, to the 

 Author, or to Mr. Sowerby, No, 2, Mead Place, Lambeth.
