Practical Photo - Micro- 

 graphy. By Andrew Prin- 

 gle, F.R.M.S. Illustrated. 

 (London: Iliffe & Son.) 

 Price 5s. 



This work will be found 

 essential to every student 

 of Photo-micrography. It 

 is written entirely from a 

 practical point of view, 

 and is couched in popular 

 language, so that it will be 

 of use even to the beginner. 

 From the manner in which 

 the author handles his sub- 

 ject, from the beginning to 

 the end, one feels that he 

 is a thorough master of his 

 craft. Not a sentence is 

 wasted, and every page is 

 packed with information. 

 Some idea of the scope of 

 the book, may be gathered 

 from an enumeration of a 

 few of the chapter headings 

 into which it is divided. 

 Commencing — Apartments 

 and General Appliances, 

 and proceeding through 

 Photo-micrographic Appar- 

 atus — Illumination — Ex- 

 amples of Procedure — 

 Colour Treatment of 

 Various Objects — Appear- 

 ance of a Plate during 

 Development and after — 

 Fixation — Lantern-Slides, 

 etc., and in a useful Ap- 

 pendix, the prices of various 

 articles. As a book for 

 work and reference, an index 

 should have been provided, 

 but this will probably be 

 remedied in future editions. 



The Country Month by 

 Month. By J. A. Owen 

 and Prof. G. S. Boulger, 

 F.L.S., F.G.S. September.

 Sands and Foster, 1894.) 

 Price, sewed, is., cloth, 2s. 



The September instal- 

 ment of this chatty resume 

 is here to time. The 

 " Coming of Autumn " is 



dealt with in a pleasantly written essay, telling of the 

 signs of change, and that the year is waning. The 

 game-birds are touched on, seeing that they are 

 now in season, and the hedgerow, the forest, and 

 a stream-side each gets its share of attention. 

 A general perusal revives old memories and many 

 pleasant associations. 



The Royal Natural History. Edited by Richard 

 Lydekker, B.A., F.G.S. , F.Z.S. Super Royal 8vo, 

 36 monthly parts. Parts x. and xi., price is., each. 

 (London : Frederick Warne and Co.) 



The two parts now before us are fully up to the 

 standard of excellence that the early issues led us 

 to expect. Part x. is devoted to antelopes and 

 deer, whilst Part xi. covers the camels, pigs, 

 hippopotami, rhinosceri, etc. 



Home Life. (From Tin Grouse 



' Fur and Feather Series.") 



The thorough manner in which these animals are 

 treated, and the depth of research shown by the 

 author is especially pleasing, and it is satisfactory 

 to look forward to the completion of what must 

 certainly prove the best Natural History that it is 

 possible to possess. 



The illustrations are as numerous as ever, every- 

 thing that it is possible to picture appearing to 

 have been done. 



We have received a Catalogue of Books and 

 Pamphlets on Astronomy, Botany, Natural History, 

 Geology, Mineralogy, etc., from Mr. John H. 

 Knowles, of 15, Rush Hill Road, Lavender Hill, 

 London, S.W., and note that the prices appear 

 very reasonable.
