Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Excerpt from Land and Fresh-Water Shells: An Introduction to the Study of Conchology The burden of this little volume of "The Young Collector Series" is to supply a want often felt and often expressed by our younger naturalists, who cannot afford to give the high prices asked for books upon the subject of which it treats. At the same time it must not be looked upon as a finished monograph, nor yet as the only manual that will be needed by the student. As he makes advances in the after-days he will require the larger text-books of Moquin-Tandon, Gwyn Jeffreys, Forbes and Hanley, Rossmassler, and my other work, "The Shell-Collector's Handbook for the Field," to which this little volume may serve as an introduction. In the following text, the anatomy of the snail and fresh-water mussel has been given at some length, since the basis of our work must be founded on structural details, and to make these chapters as full as possible, all the available sources of Continental and Home literature have been searched for information. The whole of the species of our land and fresh-water mollusca are described, and their most common varieties are given in footnotes.
