has bee A alluded to. Prof. Henslow, in ' Mag. of Zool. and 

 Bot/ (vol. i. p. 259), has admirably illustrated the arrangement 

 of the stamens in Adoxa moschatellina, in which we generally 

 find a separation of these into two parts ; the anthers conse- 

 quently appear to be one-celled : but examples occur in which 

 there is no separation, the stamens being perfect, and others 

 in which the separation is the slightest possible, and so on 

 through different degrees to total separation. 



Many other examples of adhesion or of separation might be 

 mentioned, but such must be familiar to every one who dis- 

 sects plants : may it not be inferred that in Fumaria another 

 example is presented ?

A General Outline of the Animal Kingdom. By Thomas Rymer Jones, 

 F.Z.S., Prof. Comparative Anatomy in King's College. Parts 

 I. — VI. London, Van Voorst. 



The present work, forming part of the series published by the 

 above firm, among which we find the beautiful works of Yarrell, 

 Bell, &c., has for its object a general view of the animal creation, 

 exhibiting the structure and internal ceconomy of every class of living 

 beings, and developing with as much simplicity as possible the prin- 

 ciples of zoological arrangement as based upon animal organization. 

 This difficult task, which must necessarily be to a certain extent a 

 compilation, requiring therefore a profound knowledge of the sub- 

 ject and large acquaintance with the writings of foreign authors, 

 could not have fallen into better hands. In the present state of the 

 science it is no easy matter to keep pace with what is doing on the 

 Continent ; many works which appear there are known but by few 

 persons in this country, and to this circumstance we must attribute 

 the occurrence of some slight mistakes in this work. Mr. Jones also 

 appears in part to have derived his knowledge of the researches of the 

 Germans from French sources, which are apt to mislead. With re- 

 gard to the class Bryozoa, we could have wished that the labours of 

 S. L. Loven had [been consulted, which were published in the 

 Transactions of the Swedish Academy for 1835, and translated in 

 Wiegmann's Archiv for 1837, p. 249. Prof. Jones's views respect- 

 ing the internal organization of Infusoria, as well as those of Meyen 

 and Dujardin, have been given in this Journal, as also Ehrenberg's 

 answer to the objections ; so that it is unnecessary for us to enter
