ened the remarks of M. Cuvier upon the Veretilla, Pennatulae, 

 and -41cy6nia. Other masses, till now confounded with AX- 

 cy6nia, are not even Polypi, and the living matter is distributed 

 among them as in sponges. Their only sign of vitality is, that 

 they slowly contract and close when irritated. 



M. Milne Edwards has described four new Crustacea, which 

 are very interesting, as they form links between the genera of 

 this class. Almost all are microscopic. 



M. Guerin has described two larger species, one belonging 

 to the family of crabs, which he has named Eurypoda ; the 

 other to shrimps, the eyes of which occupy nearly the whole 

 head, and which he calls Themisto. 



M. de Blainville has made some new and important observ- 

 ations on the Physalia, which has been hitherto looked on as 

 a zoophyte, and made the type of one of the orders by M. 

 Cuvier ; but from its orifices, its intestine, and muscular crest 

 or foot, M. de Blainville thinks it ought to rank with Mol- 

 lusca. To do this, however, it must possess a nervous and a 

 vascular system, a heart, a liver, &c., all of which have been 

 searched for in vain by M. Cuvier. 



Zoology continues to receive vast accessions from the nauti- 

 cal expeditions ordered by the government. Five successive 

 collections, sent by MM. Quoy and Gaymard, who have vi- 

 sited several parts of the South 8ea and the coasts of New 

 Guinea, present thousands of animals. The Chevrette, com- 

 manded by Captain Fabre, who has traversed the Bay of 

 Bengal, and touched at the Sunda Isles, has acquired great 

 treasures, thanks to the zeal of the chief surgeon, M. Rey- 

 naud, and other officers. 



In the report on Agriculture, &c. M. Giroux de Buzaraingue 

 is said to have published a memoir, stating, that wheat grows 

 much better when its roots do not penetrate too far into the 

 ground ; therefore, when the soil is prepared to receive it, 

 care should be taken to leave it in a coarse, lumpy state. M. 

 Giroux also observes, that when wheat is sown thickly, the 

 grain is better, the epidermis thinner, and the straw finer. 



M. de Beaujeu, after many years' attention to the manufac- 

 ture of sugar from beet-root (and which has by many been 

 thought for the last twenty-five years the most likely means of 

 checking the slave trade), has established a manufacture on 

 his own property, and communicated some of the results of 

 his labours. His experiments are very similar to those lately 

 adopted for sugar canes in the colonies, and he considers the 

 making of beet-root sugar in France a lucrative speculation. 



The Annales Agricoles de Roville, by M. Mathieu, of Dom- 

 basle, are continued. The particulars concerning the experi^
