Art. XIII. J/otice of M, Brongniart on Organized 

 RemainSf 



X HIS distinguished mineralogist, so advantageously known 

 by his excellent work on mineralogj' — his researches in com- 

 pany with Cuvier, into the subterranean geography of the 

 environs of Paris, and his superintendence of the great porce- 

 lain manufactory at Sevres, is attempting to form an extensive 

 collection of organized remains. 



Through Professor Cleaveland, we have received from him 

 the following 



NOTICE 



Concerning the method of collecting, labelling, and transmitting 

 specimens of fossil organized bodies, and of the accompanying 

 rocks, solicited by M. Brongniart. 



The study of fossil organized bodies appears to be of the 

 utmost importance in determining the relations of different 

 formations, one of the principal objects of geology. 



In order more effectually to appreciate the value of this 

 method of investigation, it is necessary to multiply observa^ 

 tions — to endeavour to render them exact and precise — and 

 especially to make them upon a general plan. 



M. Brongniart has been long occupied in such researches. 

 The essay published by M. Cuvier and him, upon the geology 

 of the environs of Paris, has afforded an example of their use. 



He has laboured since this period to apply this method to 

 other formations, which contain the relics of organized bodies ; 

 but he stands in need of much assistance, and he presumes to 

 ask it, not only of naturalists, but even of all persons interested 

 in the sciences. By means of the following instructions, he 

 endeavours to avail himself of the kindness of persons the least 

 conversant in the discrimination of fossils.
