sumption, that it would always prove the surest basis on 

 which a more modem superstructure might be raised. 



But, 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 what- 

 ever 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 different genera of shells, and 

 their most prominent species; and as they are from na- 

 ture, the correctness of their delineation may be depend- 

 ed upon. 



It 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 also some serviceable hints and directions towards 

 the best modes of collecting and cleaning shells.
