450 Miscellaneous. 



reviewed. Teeth, skin-prickles, whalebone, parts of skeletons, and 

 their structure are described in their places. The more theoretic 

 subjects of " ])arallelism in development," the " distribuHon " of 

 some groups of animals, the " oldest members " of some orders, the 

 "extinction of animals," and "protective resemblances" are duly 

 considered. 



The account of Chalk and its associated strata, both in geographical 

 and geological aspects, is interesting and correct ; and so is the 

 description of Flint, its nature and origin, in the succeeding chapter. 

 These two essays — on a " lump of chalk " and a " flint-flake," — 

 together with the preceding Chapter XTX., on '• Nummulites and 

 Mountains," and Chapters XV. and XVI., mainly constitute the 

 geological portion of the book, and, with the purely zoological 

 chapters, make a very useful little volume of popular natural history- 

 for those whose tastes and studies lead them to the consideration of 

 evolution, development, and mutual relationships of various members 

 of the Animal Kingdom. 



It is good and right of accomplished savants to popularize their 

 best-known sciences, and this book is a favourable sample of such 

 a work ; but its title is too curt and crude, however desirable it may 

 be to render in an elliptical form the idea of elucidating and illus- 

 trating the facts and theories of biology, so far as some of the living 

 animals are concerned, and their relationship to those whose relics 

 are found fossilized in the rocks. A similar, but Avorse, example of 

 condensing English words is shown by the cramped, ambiguous, 

 and, indeed, self-contradictory phrase "'living fossils" for Chapter XV.

The figures are mostly good, though not new; but it is time that 

 the Ilnssian Mammoth should be divested of its deceptive hoofs and 

 skin of the head ; and certainly the liocls in the Indian Elephant, at 

 page 8, bespeak the inaccuracy of the European artist.

 mj* new genus Avith the Indian genus Echo instead of witli the 

 African genus Sdpho. It is true that the milky-white jiatch at 

 the base of the wings of my type may assume a rose-red colour with 

 age, and that the nervures, which arc reddish in mine, might 

 darken with age. But ray species cannot possibly belong to Echo ; 

 and if Karsch's resembles it in any way I should be greatly sur- 

 prised at his placing it in Echo at all, had he not admitted that 

 he is wholly unacquainted with that genus, for the dilYerences
