Manual of Pharmacy and Pharmaceutical Chemistry. 

 By Chas. F. Heebner, Ph.G. Crown 8vo, pp. 213. (New York : Published 

 by the Author, 5 Gold Street. 18S7.) Price §2. 



This work, though intended for the American pharmacist, contains a good 

 deal of information likely to prove serviceable to the English student of phar- 

 macy. Metrology, Specific Gravity, and Volume receive careful notice, and 

 we think the Chemistry and Pharmacy are of high order. The articles on 

 Percolation and the Preparation of Fluid Extracts will also be found useful.

 Crown 8vo, pp. viii. — 286. (London: Hodder and Stoughton. 1888.) 

 Price 3s. 6d. 



A series of twenty familiar addresses, delivered in one of our London 

 churches to young men at their monthly Sunday evening service. These 

 " Talks " are plain and homely, and each lecture is full of interest.

 pp. loo. (London: Swann Sonnenschein and Co. 1888.) Price is. each. 



These are two of the useful series of little books known as " The Young 

 Collector Series." In the first of these, Mr. Bath describes a great number of 

 our British Birds ; he gives us also a classified list of upwards of 400 British 

 birds, with their scientific as well as common names. ]\Ir. Sharpe gives at the 

 end of the book some valuable hints on collecting and preserving birds. 



In the volume on "Silkworms," we have a History of Silk-Culture, with 

 the Life-History of the Silkworm, its Internal Structure, its Rearing and 

 Management, and its Diseases. Both books are nicely illustrated. 



Home Experiments in Science for Old and Young : A 

 repertory of simple experiments with home-made apparatus. By T. O'Conor 

 Sloane, E.M., A.M., Ph.D., etc. Crown 8vo, pp. 261. (London : Sampson, 

 Low and Co. 1888.) Price 6s. 



The object of the author has been to show such experiments as can be per- 

 formed with home-made apparatus, or without any special apparatus at all. A 

 great number of interesting and instructive experiments are described in a plea- 

 ing manner — thus we have Experiments in Mechanics, in Gravitation, Hydrau- 

 lics and Pneumatics, in Molecular Physics, with Soap Bubbles, and in Heat, 

 Sound, and Light. There is also a chapter on Scientific Lecturing. The 

 illustrations, of which there are nearly 100, are good. 



The Ready-Reference Dictionary, containing 35,000 words. 

 Edited by \V. R. Balch. Crown 8vo, pp. 344. (London : Griffith, Farran, 

 Okeden, and Co. 1888.) Price 3s. 6d. 



The chief features about this Dictionary are — ist, the fronts of the pages are 

 cut index fashion, so that the book may always be opened at the required 

 initial letter ; 2nd, the common words understood by everybody are, as a rule, 

 omitted ; and 3rd, each word is carefully pronounced. The meanings given to 

 the different words-are short and to the purpose. 



A very handy dictionary, and convenient for reference. 



A Higher Arithmetic, and Elementary Mensuration for the 

 Senior Classes of Schools and Candidates preparing for Public Examinations.
