 important memoir on the Carnpanularice of the coast of Ostend, by 

 M. Van Beneden (see ' Memoires de 1' Academic Royale de Bruxelles,' 

 vol. xvii.), with a ])late. The author maintains (from observation) 

 that the Carnpanularice are viviparous, and that the young, or the 

 common substance of the ovarian cell, have been wrongly regarded 

 as a female. The eggs, like the buds, are the products of the com- 

 munity. The individuals have no sex. The young Campatiularice 

 towards the middle of their embryonary life have the form, organi- 

 zation, habits and mode of life of Medusae. In this state they have 

 muscles, nerves and organs of sense, which, when the embryo be- 

 comes fixed in order to give rise to a new colony, disappear, so that 

 the young animals are more elevated in their organization than the 

 adults ! — On a new genus of Medusce proceeding from the metamor- 

 phosis of Syncoryne, by M. F. Dujardin. The observations in this 

 interesting paper agree so far as they go with those of M. Beneden ; 

 the medusa state of the polypes was, however, some years ago de- 

 scribed by Sir John Daly ell. 



Botany. — Dutrochet on the movements of Plants (concluded). 

 The movements of plants are automatic ; they result neither from in- 

 telligence nor from will. They^ depend on an interior and vital force, 

 of which the action is revolutive, and which the author maintains 

 exists in all vegetables, but manifests its existence rarely, and only 

 in those revolutive movements appreciable by our senses. — Dutrochet 

 on the Inflexion of Vegetable Stems towards coloured light. The 

 stems of plants placed in light transmitted through coloured glass 

 elongate much more than they would have done under the influence 

 of ordinary light. — M. A. Trecul on the fruits of Prismatocarpus Spe- 

 culum and hyhridus, and on that of the Cruciferte (with a plate.). The 

 author arrives at the following curious conclusions, some of which 

 are not a little opposed to established morphological notions : 1st, 

 between the structure of the fruits of Prismatocarpus Speculum and 

 hybridus and that of their stems, there exists such a similitude that 

 the fruit appears to be the continuation of the stem, its summit mo- 

 dified for reproduction ; 2ndly, that the sepals, the petals and the 

 stamens of the same plants spring really from the summit of the 

 ovary ; 8rdly, that the partition of the fruit of Cruciferce is simple ; 

 4thly, that the stomata are not confined to the surface of plants, since 

 they are found on the partitions of certain cruciferous fi'uits. — M.
