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 Manual of the Land and Fresh-Water Shells of the British Islands: With Figures of Each of the Kinds The description of the species is preceded by a general outline of the distribution of molluscous animals; and the genera have been distributed into natural families from characters taken from the con sideration of the animal, which alone can be regarded as the proper subject for classification. Every day proves, to the scientific conchologist, that every modification in the structure of the animal impresses its character on the shell, and that the shells thus afford good subsidiary characters for the distinction of groups.
