1897] SOME NEW BOOKS 349 



Prof. Jeffrey Parker's "Elementary Biology,' in its new form, 

 differs from the preceding editions in the increased attention devoted 

 to the higher animals and plants. The general chapter on the higher 

 animals has been expanded into four beautifully-illustrated chapters, 

 dealing respectively with an outline - classification, the starfish, the 

 crayfish, the fresh-water mussel, and the dogfish. The additional 

 botanical matter refers in the same style to Equisetum, Salvinia, 

 Sclaginella, the Gymnosperms, and the Angiosperms. These supple- 

 mentary sections will indeed, as the author himself remarks, contri- 

 bute much to the usefulness of the book. 



Prof. Newton Parker's second English edition of " Wiedersheim " 

 may almost be described as a new book. The original descriptions 

 and arrangement are retained as far as possible, and most of the old 

 figures are reproduced, although a few have been replaced and others 

 added. Prof. Wiedersheim has also revised the whole. But to bring 

 the work up to date, and at the same time not increase the size of the 

 volume, it has been necessary to abridge much of it and recast other 

 portions ; while the useful bibliography in the appendix has been 

 considerably expanded to increase its usefulness to advanced students. 

 We only notice one serious blemish, namely, the unreliable character 

 of some of the references to the skeleton in extinct animals. The 

 figures of the pelvic arch of Plesiosaurus on p. 115 are quite errone- 

 ous, and might easily have been replaced. " Ldbyrinthodon rueti- 

 mcyeri " is certainly not a labyrinthodont. The wing-finger in the 

 Pterodactyles is not the fourth but the fifth digit. Before the next 

 edition we would suggest that this section of the work be submitted 

 to someone skilled in vertebrate palaeontology for revision. 



Sceaps from Serials 



Me Adrien Dollftjs has paid considerable attention to the terrestrial 

 Isopoda, the wood-lice of the world, and has published a paper in the 

 October number of La Feuille des Jewries Naturalistes showing the wide 

 range of some of these little animals. Considering the mode of life of 

 these Isopoda, it is not at all surprising to find certain species have a 

 wide distribution, but it is interesting to have this distribution put on 

 record. 'The species dealt with are Armadillo murinus, Brandt ; 

 Armadillidium vulgare, Latr. ; Porcellio scaber, Latr. ; P. laevis, Latr. ; 

 M ' etoponorthus pruinosus, Brandt; Ligia exotica, Roux. Of these five 

 the Metoponorthus has the widest range, being recorded for America 

 (N. to S.), Azores, etc., the whole of Europe, Africa (N. to S.), Asia 

 (E. to W.), and Australia (N. Caledonia and Marianna Islands) ; Por- 

 cellio laevis is the next most widely distributed, having much the same 

 range as the Metoponorthus, but found also in the Bermudas, Mel- 

 bourne, and various islands of Oceania, and restricted to the N. of 

 Africa. A sketch map accompanies the paper, which has an additional 

 value in that it mentions the collections in which the particular 

 specimens recorded are to be found. 



The American Journal of Psychology, vol. viii. No. 3, contains a 

 ' Study of Apperception,' based on experimental work on the reading 

 of words by Dr Pillsbury. Typewritten words photographed on lantern 

 slides were projected on a ground-glass screen, and exposed for two-
