two parts, the first general in character and the second more 

 specialized. In the first part, among the subjects treated, the fol- 

 lowing may be particularly mentioned : stains and staining, the 

 glycerine method, the Venetian turpentine method, and the paraf- 

 fin method. In the second part the various groups of plants and 

 the methods especially adapted to their study are considered. 

 When compared with the earlier editions the changes to be noted 

 are largely in matters of detail, although an interesting chapter 

 on photomicrographs and lantern slides has been added.

8. Laboratory Manual of Horticulture, with illustrations of 

 methods, equipment, and apparatus ; by George W. Hood. Pp. 

 vi, 234; with 52 text-figures. (Ginn & Company, 1915. Price 

 $1.00.) — The present manual is an outgrowth of courses in horti- 

 culture given by the author at the Ohio State University and 

 other institutions. It is thoroughly practical in character and 

 gives directions for seventy-eight exercises to be carried on in the 

 laboratory or in the garden. Following each exercise is a blank 

 page for the student's notes. The greater part of the book is 

 devoted to cultivated fruits, and the various methods of budding 

 and grafting are clearly and fully described. a. w. e. 



9. .Bacteriological Methods in Food and Drugs Laboratories; 

 by Albert Schneider, University of California. Pp. 277 ; 93 

 illustrations. Philadelphia, 1915 (P. Blakiston's Son & Co.).— 

 An admirable guide for analysts engaged in the sanitary examina- 

 tion of foods. It embodies standard methods of bacteriological 

 investigation, as well as more recent and untried methods which 

 promise to be of practical value in this field. Unification of bac- 

 teriological procedure appears to be the keynote. The first 

 chapter of twenty-three pages with six full-page plates is devoted 

 to micro-analytical and chemical methods of detecting certain 

 food substances and food adulterants and impurities. The remain- 

 der of the book is devoted to bacteriological technique and closely 

 related matters. Of particular interest is the part treating with 

 the detection of bacteria and moulds in canned soup, catsups and 

 other preserved foods. l. f. r. 



10. Publications of the Astronomical and Astrophysical 

 Society of America. Volume II. Pp. 240, with numerous illus- 

 trations. Ann Arbor, Michigan, 1915.— This volume contains a 

 summary of the five meetings of the Society, beginning with the 

 eleventh meeting in 1910 and extending to the fifteenth meeting

 with considerable fullness. Of especial importance is the report 

 of the Comet Committee of 1909-1913, having particular refer- 

 ence to the return of Halley's comet in August, 1908. The obser- 

 vations upon it at various points are given in detail and some 

 twenty-eight plates present the results of the photographs of the 

 comet at Diamond Head, Hawaii, by Ferdinand Ellerman, with 

 notes upon the same by E. E. Barnard.
