Short Studies in Physical Science. Mineralogy,

 M.Sc. 230 pp. Svo; illustrated. (London :

There are sixteen chapters in this book, three 



subject. We reproduce the latter of these illustra- 

 tions, by permission of the publishers, to show 

 the high tone of the work and its production. 

 We can cordially recommend the book, especially 

 to those students who know something of the 

 subjects treated by Mr. Cornish in its pages. 



A Handbook to the Order Lcpidoptera. By W. F. 

 KiRBY, F.L.S.. F.E.S. Vol. 3, Part i. Butterflies 

 concluded — Hesperiidse, Moths. 308 pages 8vo, 

 illustrated by 27 Coloured Plates and numerous 

 figures in the letterpress. (London : W. H. Allen

This is the third of the proposed five volumes on 

 Lepidoptera, to be included in "Allen's Naturalists' 

 Library," the former two being noticed in this

being devoted to mineralogy, six to chemistry, and 

 seven to physics. Some have appeared already in 

 serial literature, but for the most part they are 

 new. Some of the chapters in chemistry are more 

 or less historical, dealing with Elements and 

 Atoms and Chemical Classification. In Chapter v. 

 Menaeleeff's System is discussed. The illustration 

 to the chapter is a portrait of that eminent Russian 

 chemist. Another is a reproduction of an X ray 

 photograph, by Newton and Co., of Fleet Street, of 

 an English grass-snake, as an example of pictures 

 to be taken by the agency of Kontgen ray 

 photography, Chapter xiv. dealing with the 



magazine (N.S., vol. i., p. 256; vol. iii., p. 45). 

 The present one contains the last family of the 

 butterflies — Hesperiida;, and the first twenty-six 

 families of Moths. Nomenclature again has 

 received some additions and alterations in this 

 book, but may be followed by the synonymic 

 references at the commencement of the description 

 of each species referred to. For instance, Calli- 

 morplia hera gives way to Hubner's Euplagia and 

 quadyipunctaria (Poda, Mus. Grasc, p. S9, 1761). 

 Linnajus named this species hcra in 1767, so Poda's 

 other name has priority. The handsome coloured 

 plates in this volume make a brave show.
