76 New Patents. [July, 



same naturalist has communicated to the Class peculiar and 

 interesting observations in natural history, which he made during 

 his voyage in the Levant, the publication of which has been 

 interrupted by the longer and more dangerous voyage which he 

 made in the Entrecasteaux, an account of which was given to 

 the public several years ago. 



M. Gouan, correspondent of the Class at Montpellier, has 

 published a description of the generic characters of the ginko 

 LUoba, a singular tree of Japan, which has been long known in 

 Europe, but which, never having blossomed, could not be pro- 

 perly classified in the system. 



There is a family of plants much less important than the 

 grasses in point of utility, but much more singular in their cha- 

 racters, and which can only be seen vegetating on the sea-shore, 

 namely, the fuci, and marine plants analogous to them. M. 

 Lamouroux, professor of natural history at Caen, placed favour- 

 ably in a city so near the coast, has made these plants a particular 

 object of study. He gives them the common name of thalassio- 

 phytes, and divides them into various tribes, the characters of 

 which he has been obliged to take in all parts of the plant, 

 because he could not find sufficient characters in the organs of 

 fructification, which usually serve as a basis to these divisions; 

 but which are too little known in most of the fuci, to be able to 

 confine oneself to them. This is another of those laborious and 

 useful undertakings which we have to regret that we cannot 

 analyse in a summary so short /as ours. Let it suffice to join our 

 voice to that of the Commissioners of the Class, to request the 

 speedy publication of it.
