recognised by the scales or remains of the leaf- 

 stalks with which it is covered: it was found at 

 Vailly, near Soissons, by M. Menat, who gave it to 

 the Museum. 



5th. Two beautiful impressions of leaves of 

 the chamaerops palm, given by M. A. Brongniart, 

 taken out of the quarries in the neighbourhood 

 of Aix, near Marseilles. 



Lastly. A numerous series of impressions of 

 leaves on the newer limestone, found at Monte 

 Bolca, on the confines of the Veronese and Vi- 

 centine in Italy. 



The invertebrate d fossil animals are in the cases 

 to the right of the entrance : they are divided 

 into three sections: the zoophytes or radiated 

 animals, the articulated animals and the mollusca. 

 Each section is subdivided according to the age 

 of the formations from which the specimens 

 were taken: that is, we see in each section the 

 species which characterize either the transition 

 or intermediary, the secondary, or tertiary 

 formations. This distribution, although merely 

 geological, is so much the more advanta- 

 geous here, as many specimens belonging to 

 the first and third sections, and remarkable for 

 their insulated position and beautiful preser- 

 vation, have been inserted in the great collec- 

 tion of zoophytes and living mollusca on the 



16.
