CONCHOLOGY is that branch of natural history which treats of shells, distributes them into genera and species, and describes the character and economy of the animals which inhabit them.
To some, the examination of this department of sci ence has appeared useless, and unworthy to occupy the time and talent of an informed mind. Reasoning, with persons of this description, is seldom attended with any good effect. Ignorant of the advantages which have re sulted to mankind, from an intimate acquaintance with natural objects, they overlook the steps by which they have been gained : and likewise seem to forget, that the examination of those objects, which an all-perfect Being has created, can never be degrading to man, who was sent into this world in order to examine, admire, and adore.
Besides, if we attend to the variety of forms which shells exhibit, and to the richness of their colouring, we will not be surprised that they have obtained a con spicuous place in public collections, and have attracted the notice of the curious observer. But to view shells merely as objects of beauty, without attending to the animals of which they form only a part, would be to overlook by far the most important branch of the sci ence; and, like the florist, to take notice of colour and shape, and neglect to attend to those functions which, while they excite our astonishment, exhibit marks of design. The examination of the contained inhabitants,
enlarges our knowledge of the laws of animal life, and teaches us that each shell, however insignificant it may seem to be, possesses faculties suited to the supply of its wants, and to the situation which it is destined to oc cupy.
But we are not disposed to rest the claims of the sci ence of conchology to public favour, altogether on the grounds which we have now stated. As objects of uti lity to man, shells deserve our notice. Many species supply his table with agreeable and nutritious dishes; others form most enticing baits for catching fish, or fur nish materials for the manufacture of different kinds of dress. The pearl is prized as an ornament, and the Tynan purple is deservedly held in estimation.
We must view shells likewise as the enemies of man, and entitled to his consideration. Some are deleterious to his constitution, while others defeat his plans. The Bernacle, by adheria.; to the bottom of ships, impedes their motion ; and the Teredo pierces their planks, and destroys them.
When these circumstances are duly considered, the science of conchology will appear of importance, as it un folds the history of objects of beauty, curiosity, and utility.
