Ir is a circumstance no less to be lamented than wonder- ed at, that, in the present enlightened age, when the culti- vation of science, and natural history in particular, is so eminently conspicuous, Conchology, or. the natural history of shells, should have participated so sparingly of that ac- tive spirit of research and investigation, which has been so lavishly bestowed on almost all other branches. One obvious reason, however, may be assigned, why Conchology has remained so long stationary in the lists of improvement. Till lately, no publications on shells have appeared, but such as were abstruse, voluminous, expen- sive, and difficult of access; and as most of them were in languages not always thoroughly understood, the attain- ment of knowledge through their means frequently be- came a source of difficulty and trouble. Ir is perhaps from this very circumstance, that many individuals whe possess fine and rare shells, are totally ig- a2 iv norant of any systematic mode of arranging them; the consequence is, they are suffered to remain in the cabinets like a collection of unknown gems, whose intrinsic value their proprietor being unacquainted with, they are incapa- ble of affording amusement, information, or profit to him. INFLUENCED by the repeated observation of the occur- rence of these difficulties, it appeared desirable, that the public should be put in possession of some compendious or abridged treatise on Conchology, which would at once enable the young student to arrange his collection syste- matically, and at the same time tend to enhance the value of that science, which, for want of a proper key, or book of introduction, has remained too long in neglected ob- scurity. To accomplish this, it appeared only necessary to select the choicest materials contained in more elaborate works, and arrange them in such order as would afford all the in- struction requisite for the information and improvement of the young Conchologist, in a concentrated, perspicuous, and purchasable form. Ir has been made a point, throughout the work, to ad- here rigidly to the. Linnzan system, on the strong pre- sumption, that it would always prove the surest basis on which a more modern superstructure might be raised. Vv Bur, as other less celebrated naturalists have also con- tributed their quantum of information on the subject of Conchology, it has been thought prudent to add whatever they have urged of most importance; and as it is a matter of consequence for the learner to call in the aid of figures as well as description, it was thought proper to annex fac- similes of the most prominent species of the different ge- nera of shells; and as they are from nature, the correct- ness of their delineation may be depended upon. Ir was also deemed necessary, in order to render the work more generally useful and acceptable, to submit a concise account of the nature, habits, and uses of shell-fish ; as weil as some serviceable hints and directions as to the best modes of collecting and cleaning shells.
