A Manual of Paleontology. By Henry Alleyne Nicholson, 

 M.D., D.Sc, &c, Professor of Natural History and Botany 

 in University College, Toronto. Edinburgh and London : 

 Blackwood and Sons. 1872. 

 Dr. Nicholson's object has been to furnish the student of 

 geology and the general reader with a compendious account of 

 the leading principles and facts of the vast and ever-increasing 

 science of Palaeontology. The work is divided under four heads : 

 — the first includes a general account of the principles upon 

 which the palaeontological observer proceeds ; the second treats 

 of the past history of the animal kingdom, devoting much more 

 space than is generally accorded to the consideration of inverte- 

 brate groups ; under the third head is given a comprehensive 

 view of paleobotany, or the past history of the vegetable king- 

 dom ; while, finally, the author applies the principles of palse- 

 ontological science to the elucidation of the succession of the 

 stratified deposits of the earth's crust. To say that this is the 

 best handbook yet produced by the prolific pen of Dr. Nicholson 

 is to accord the highest praise. The work is profusely and well 

 illustrated. 



Elements of Zoology. By Andrew Wilson, Lecturer on Zoology, 



Edinburgh. Edinburgh : Adam and Black. 1873. 

 This is a manual intended to convey the principle of the division 

 of zoological science to the student of an elementary course. 

 The explanation is terse, but sufficient ; the illustrations are 

 numerous and well selected. 



A Manual of Elementary Chemistry, Theoretical and Practical. 



By George Fownes, F.R.S., late Professor of Practical 



Chemistry in University College, London. Eleventh Edition. 



Revised and Corrected by Henry Watts, B.A., F.R.S. 



London: J. and A. Churchill. 1872. 

 The eleventh edition of this well-known manual of chemistry 

 presents some marked alterations. The work, under the careful 

 editorship of Mr. Watts, fully keeps pace with the progress of 

 chemical science. But the volume appears overgrown : if the 

 matter were divided under the heads of organic and inorganic 

 chemistry, and each portion included in a separate volume, the 

 manual would take a much handier form. The present volume
