The " Philosophical Transactions" of our own country for the 

 following year contain an account of some of the shells of the 

 Philippine Islands, communicated by Petiver from 



KAMEL, 



many of whose papers occur in that work, and who illustrates his 

 descriptions by references to the plates published by his corre- 

 spondent. 



HANNEMAN 



may be considered as the author of an academical dissertation, 

 " Ostrea Holsatica exhibens," of which Hans Roslin was respon- 

 dent, and which was illustrated by a plate. It is copied into Va- 

 lentini's Amphithcatrum Zootomicurn, hereafter to be mentioned. 



REAUMUR, 



whose name is immortalized among naturalists by the perseve- 

 rance and profoundness with which he studied the structure and 

 oeconomy of the smaller animals, deserves to occupy a distin- 

 guished place in the catalogue of Testaceological writers. To 

 this illustrious zoologist we are indebted for several admirable 

 dissertations on the formation, growth, and motive powers of 

 Testacea. The memoirs of the French academy from the year 

 1709 to 1717 derive from his labours a large share of their value ; 

 and to the details of his various curious discoveries contained in 

 them recourse will be had with delight and advantage so long as 

 the science of nature shall be loved. Each of his papers is illus- 

 trated by excellent plates, exhibiting several of the species de- 

 scribed, and various parts of their internal structure; and each 

 may be considered as the most complete, with respect to the sub- 

 jects on which it treats, of any similar dissertations that had 



hitherto appeared.
