458 EXPERIMENT STATION RECORD. 



Fumigatloii method for sacked cotton seed, W. E. Hinds (Jour. Econ. Ent., 

 8 (1915), No. 4, pp. 400-402. pi. i).— The author describes a method of fumi- 

 gating cotton seed with carbon disulphid that has been worked out in Ala- 

 bama. With this method it has been found possible, with four men to do the 

 work, to treat 600 or more sacks per day. 



The Acarina or mites: A review of the group for the use of economic ento- 

 mologists, N. Banks (U. S. Dept. Agr. Rpt. 108 (1915), pp. 153, figs. 294).— The 

 work previously noted (E. S. R., 17, p. 882) has been revised and enlarged and 

 brought up to date. Many new illustrations have been added. 



Two introduced worms of economic interest, H. Gabman (Jour. Econ. Ent., 

 8 (1915), No. 4^ PP- 403, 404)- — The author records the occurrence of Bipalium 

 kewense In a greenhouse at Lexington, Ky., and of Hcterodera schachtii at 

 Spreckles, Cal., where it is a destructive pest of sugar beets. 



Some feeding habits of slugs, Marie V. Leboub (Ann. Appl. Biol., 1 (1915), 

 No. 3-.'i, pp. 393-395). — The author reports upon studies of the habits and food 

 of two species of slugs (AgrioUmax agrcstis and Arion circumscriptus), made 

 during the course of an investigation of the broad tapeworm of lambs (iloni- 

 ezia expansa) at the University of Birmingham. Both of the slugs appear to 

 be fond of Monlezia, and also of Cittotctnia pectinata which infests rabbits in 

 that vicinity. The author failed to find evidence that either of the two slugs 

 acts as intermediate hosts for M. expansa or C. pectinata. 



The chromosome cycle in Coccidia and gregarines, C. Dobeli. and A. P. 

 Jameson (Proc. Roy. Soc. [London], Scr. B, 89 (1915), No. B 610, pp. 83-94, 

 figs. 2). — The work here reported has been carried on with the coccidian 

 Aggregata eberthi and the gregarine Diploci/stis schncidcri. 



Careful investigation of these two organisms is said to have shown that the 

 nuclear divisions at all stages in the life histories are mitotic, and that the 

 chromosome numbers are remarkably constant. The life history of this coccidian 

 comprises a sexual generation which takes place in the body of a cuttle-fish 

 (Sepia officinalis) and an asexual generation in the body of a crab (Portunus 

 depurator). The life history of D. schncidcri is passed In a single host, a cock- 

 roach, having been studied chiefly In Pcriplanctn nmcricann, but was also found 

 In Stylopyga oricnialis. 



FOODS— HUMAN NUTEITION. 



Household chemistry, II. T. VuLTfi (Easton, Pa.: The Chemical Publishing 

 Co., 1915 pp. yi+23S). — This book is intended as a text-book for students in 

 home economics, in secondary schools, or in colleges, and considers the principles 

 of chemistry as they apply to and are illustrated in the household. Among the 

 subjects considered are the chemistry and physics of air as related to ventila- 

 tion ; the chemistry of water, metals, glass, pottery, etc. ; and the chemistry of 

 foods, to which considerable attention is given. Chapters are also devoted to 

 the consideration of methods of disinfection and the chemistry of .soaps and 

 other cleaning agents. The elementary principles of volumetric and gravimetric 

 analysis, as they apply to household chemistry, are outlined very briefly. 



Index to reports on food products and drugs of the Connecticut Agricul- 

 tural Experiment Station, 1896-1914, J. P. Street (Connecticut State Sta. 

 Bui. 187 (1915), pp. 94). — The object of this index is to collect in one publica- 

 tion all the references to the food and drug work of the station. This work 

 covers a more or less complete analysis of about 26,000 samples of foods, and 

 the examination of about 3,000 samples of drug products to detect adulterations 

 or variation from required standards.
