save the cost and inconvenience of wall charts. From the list, which 

 is all that we have seen, it appears that the photographs have heen 

 taken from the works of the various standard authors on the 

 particular subject represented. Thus for the 17 protozoa, Claparede 

 and Lachmann, Ehrenberg, Haeckel, Schulze, and Stein have been 

 referred to. There are 20 representations of coelenterates, 20 of 

 echinoderms, 43 of worms, 21 of Crustacea, 20 of insects, myriapods, 

 and arachnids, 22 of moUusca, and 17 of vertebrata. 



Bachmann's Guide for making Microscopical Preparations.— 

 This book (in German, 196 pp., with 87 woodcuts), after a descrip- 

 tion of the necessary instruments and reagents, explains the methods 

 of preparing slides of plants, insects and spiders, mollusca, blood- 

 corpuscles, microscopical inhabitants of water, hard substances, 

 trichinae, entozoa, bacteria, and preparations of vertebrate normal 

 histology. 



The author enforces the importance of keeping a " Preparation 

 Journal," and gives an extract from his own, which is arranged as 

 follows : — 



Beauregard and Galippe's Practical Micrography.— This is a 

 book (in French) of 900 pages, with 570 woodcuts. Besides the 

 usual preliminary chapter on " Microscopes and their Employment," 

 it consists of two pavts, " Vegetable Histology," and " Animal 

 Histology." In the former are included (in separate chapters) the 

 anatomical elements, tissues, structux'C of stems, roots, and leaves, and 

 the organs of reproduction of Cryptogams and Phanerogams. The 

 latter deals witli blood, jnis, sediments of urine, milk, semen, faecal 

 matters, parasites, mucus, vomited matters, stains of various kinds, 

 and the examination of water and the atmosphere and of hairs from 

 a nicdico-legal poiut of view. 



Microscopical Journals. — We have received no parts for a long 

 time of tlie German ' Zeit.schrift fiir Mikroskopie,' or of ' Brebissonia, 

 a Journal of Algology and Microscopical Botany.' The last number 

 of the French ' Journal do Micrographio ' is August, and of the 

 ' American Journal of Microscopy ' September. The ' American 

 Quarterly Microscopical Journal ' ceased to api)ear on the completion 

 of its first volume, but we are glad to hear that Professor Romyn 

 Jlitchcock (one of the Fellows of this Society), who so ably edited it, 

 is about to issue a new inoiitlily microscopical j(Hirnal.
