THE GEOLOGIST. 



As examples of the figures of fossil moUusca, we cannot 

 do better than select the following plate. 



1. Lima rudis, 2. Pectan vagans. 3. Plagiostoma rigidum. 4, Avicula inequivalvis. 

 5. Trigonia-costata. 6, Terebratula globosa. 7. Modiola plicata. 

 8. Pinna lanceolata. 



We have thus noticed the several points in this work, 

 which deserve particular attention, and we think that Mr. 

 Richardson has certainly gained the object which he 

 proposed, and has produced a work, which can be safely 

 recommended to the student of geology, both for general 

 clearness in arrangement and completeness, embracing as 

 it does the records of the most important facts in the 

 science to this time. We only think that the author has 

 been indiscriminate in his comments, and has eulogized, 

 in particular, the researches of too great a number of 

 geologists ; — but he is an F.G.S., and we can excuse this 

 error.
