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, fyc. 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 Lite Botanist, Couchologist, 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, &c. 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 die use of his friends and for the benefit, of students and 
lovers of natural history. The many rare and interesting specimens 
which this collection contains arc 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 
desiderata. 
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.
