PREFACE. 



V 



The remaining part will contain the Bivalves, Multi- 

 valves, and the Sub-Coronalia and V ermicularia of La- 

 marck (the Brachiopoda and Tubicolce of Cuvier) : a 

 figure of the entire shell, of each valve, and of the hinges 

 and teeth, when at all complicated, will be given. The 

 Animals and Fossil Genera will also be included. 



I beg to repeat that this Manual, as well as the others, 

 has been compiled for those of my countrymen, whose 

 remote situations in our colonies do not permit of their 

 acquiring so desirable a species of knowledge, by the study 

 of collections ; as well as for those who, like myself, may 

 cultivate Natural History, as the most agreeable delasse - 

 ment to mathematical studies. 



Paris, November 8, 1821.
