314 Cure fcr the Kheumatifm and Gout. 



Girod-Chantrani has ir-ade obfervations on different kinds 

 of confervas, but chiefly the rivularis and fontan . He main- 

 tains his firft opinion, and believes thefe produ6lions to be 

 the habitation of animals. 



Dccandolle has examined, with Brogniard, the ftrufture of 

 marine plants, fuch as the f net; he finds that they have a. 

 great affinity to the conferv:e. 



Morellot has given obfervations on the leaves of trees, 

 with the figns which announce their being in full vigour, 

 and the time vi.hen they ought to be collected for pharma- 

 ceutical and economical purpofes. He {hows that it is at the 

 period when the plant is in flower that the leaves poflTefs their 

 full virtue. They drop when their particular life is termi- 

 nated.
