NOTICES OF KECENT BOOKS. 



Photo-micrography. By Edmund J. Spitta, L.R.C.P., etc. 

 Demy 4to, with 41 half-tone reproductions, and 60 figures 

 in text. London : The »Seientific Press, Ltd. Price 12.9. 



This is probably the most elaborate work yet published on the 

 subject, which is yearly gaining favour as a means of book 

 illustration, and indeed bids fair to drive the wood block almof>t 

 entirely from the Held it once held supreme — a fact, we confess, 

 we are old-fashioned enough to regret. The subject-matter is 

 treated throughout in such a manner as to give the intending 

 photo-micrographer the utmost service a book is capable of afford- 

 ing ; it will not make him a master of the art by mere perusal, 

 but it will show the practice of an expert, and by adopting the 

 author's methods to begin with the beginner may avoid some 

 natural errors, and finally, as most workers seem to do, he will 

 originate a procedure of his own. Mr. Spitta's book covers the 

 whole ground, from magnifications of 1| to 3,000 diameters, and 

 the half-tone reproductions by Dent & Co. show extremely well 

 the advantages and, may we say, the disadvantages of this form 

 of black-and-white process work. 



The Science or Life. By J. Arthur Thomson, M.A. London 

 Blackie & Son. Price 26*. 6o?. 



This is an outline sketch of the history of Biology and its main 

 advances during, approximately, the period covered by the present 

 reign. It consists of sixteen chapters dealing with the origin, 

 development, and present position of classification, morphology, 

 physiology, and embryology of plants and animals, the cell and 

 evolution theories, and other biological problems; and although 

 the treatment of each is necessarily brief it is most cleai-, 

 luminous, and to the point. Altogether the book is an excellent 

 digest of a very fascinating subject, and should be read by every 

 member.
