Gaillon's Apercu (VHistoire Natiirelle* " 189 



which it will communicate) in leading us, as well as to the 

 discrimination and cognizance of our native species, to the 

 apprehension of principles of universal, delighting, enlight- 

 ening, empowering application. 



The descriptions of the sections, subsections, families, 

 genera, and species are, in a good degree, detailed ; yet, we 

 think, lucid. Short, but pleasing, notices of the habits are 

 interspersed ; the internal anatomy of many species is noticed ; 

 the derivation and literal meaning of many generic names are 

 given; the descriptions are all in English, and have been 

 derived from a familiar, a living acquaintance with the crea- 

 tures described; or, in the case of the rarer and very rare 

 species, from a diligent and judicious reading. A very 

 pleasing and a truly useful introduction of 59 pages is prefixed 

 to the work.

 Aper^u d'Histoire Naturelle, et Observations sur lesLimites

This is an address read before the Society of Agriculture, 

 Commerce, and of the Arts, of Boulogne sur Mer, at its 

 meeting of Sept. 19. 1832. The greater portion is occupied 

 with a review of the principal classes into which animals and 

 vegetables have been divided, written in a rather declamatory 

 style, and of no further interest or use than as serving to 

 introduce the views of M. Gaillon respecting those sorts of 

 ^'Igae which inhabit the debatable grounds that lie between 

 the two kingdoms of organised beings. The A'\g8e alluded 

 to are composed of globular or lenticular granules lying loose 

 and disconnected, or embedded in a transparent mucus, or 

 compacted together on a slimy membrane, or enclosed within 

 capillary tubes which divide and branch away exactly after 

 the fashion of acknowledged Confervas. They form the fami- 

 lies Diatomaceae, Gloiocladeae, ^yssoideae, and Oscillatoriae, 

 and embrace some of the genera of the Conferveae, Siph^ineae, 

 and t/lvaceae of Dr. Hooker's English Flora, (vol. v.) Now, 

 all of these, M. Gaillon maintains, are animals, and, under the 

 name of Nemazoaires, ought to be transferred to the animal 

 kingdom ; for he has seen, and many others have witnessed 

 the same phenomena, the granules, both in the separate and 

 combined state, move from place to place, as if actuated by 

 volition ; he has seen them, when stationary, perform motions 

 to and fro on some fixed point ; he has seen them change 

 their form, dilate, and contract ; and he has seen a globule of 

 little coloured grains ejected from the interior, which, he main-
