useful work (Chapters XXL-XXVIIL, pp. 266-390). This Part iv., 

 entitled "the examination of fossils," is a condensed and matter-of- 

 fact treatment of the subject, and probably, as far as it goes, the 

 best of its kind yet published. The relationship of palaeontology 

 to zoology, and the extent to which either need be studied by 

 students working for a good pass-examination, or by amateurs 

 earnestly desirous of getting some mastery of the subject, are kept 

 well in view. How fossils are found preserved in the strata, and 

 how they may be preserved when they have been found in quarries 

 and other sections, form a brief introduction to the study of fossils. 

 The chief genera, or generic types, of Invertebrata are then concisely 

 treated of in the order of their natural groups, from the Protozoa to 

 the Crustacea, with notes on their distribution in the Geological 

 series. Chapter XXVIII. is the last (pp. 379-390), and consists of 

 a condensed " list of characteristic invertebrate fossils " for each of 

 the geological formations from the " Harlech series " of the Cambrian 

 upwards to the " Chillesford Beds " of the Pliocene. 



To those who are especially desirous of working out the history 

 of the Earth by such elucidation as petrology can give, this manual 

 will be a very great help. An acquaintance with strata in their 

 orderly arrangements and in their disturbed conditions is supposed 

 either to have been attained, or to be looked for in other handbooks. 

 So also the history of the formation of the strata in successive ages. 

 Fossil remains of the vertebrate animals and of plants are also left 

 to other teachers. With these intentional omissions, for reasons 

 intimated or given in full, the book is very good for its purpose, 

 being full of well-digested information, for the most part from the 

 newest sources of information, and often from the author's personal 

 research. 



Of the 136 woodcut illustrations, 17 are concerned with apparatus 

 necessary to the mineralogist and petrologist ; 28 illustrate micro- 

 scopic sections of rocks ; and 91 are given to the fossils. A careful 

 Index completes the work. 



The Honey-Bee : its Natural History, Anatomy, and Physioloc/y. 

 By T. W. Cowan, F.L.S., F.G.S., &c. Houlston & Sons : London, 

 1890. 



There is probably no other insect which can boast of so voluminous 

 a literature as this ; and for pi'ecisely this reason the present little 

 volume, the latest addition, will be heartily welcomed. In the short 

 space of some 190 small octavo pages the author gives a concise 

 account of the chief facts in the anatomy and physiology of the 

 Hive-Bee, as now established after the discoveries of older workers 

 have been tried by the ordeal of modern methods of investigation. 

 Except in the case of facts long ago accepted, the names of 

 authorities for statements in the text are in all cases given, and
