 telarius, H. E. Ewing {Jour. Ent. and Zool., 6 (191Jf), No. 3, pp. 121-132, fig. 

 1). — ^A detailed report on the distribution of this pest, including a map which

Preservation of comm.ercial fisli and fishery products in the Tropics, A. 

 Seale {I'liUippine Jour. ScL, Sect. D., 9 {19U), No. 1, pp. 1-11, pis. 2).— Pre- 

 serving by drying and salting, smoking, marinating, canning, and by low 

 temperature or refrigeration is considered as well as the preparation of tish 

 for shipment. Philippine conditions are discussed and details of methods of 

 preservation quoted, in a number of cases the material being taken from the 

 reports of the United States Fish Commission. 



Cows' butter and its substitution with artificial products, A. O. Webeb 

 (Vrachebnaya Ga^. [St. Petcrsh.], 19 {1912), No. 4, pp. ISO, iSJ).— This article 

 deals with the composition of butter and some of its substitutes in the diet. 



The author concludes that the substitution of artificial products for butter i? 

 desirable from the standpoint of health as well as economy. Preparations of 

 vegetable fats, particularly those from coconuts, are deemed especially suitable 

 for foods, owing to their cheapness, ease of use, and ready assimilation. 

 From a summary of clinical observations it is concluded that the use of coco- 

 nut butter as the source of fat in the diet of tuberculous patients gives very 

 satisfactory results on account of its ease of assimilation. 



The composition and quality of Mexican wheats and wheat flours, C. H. 

 Bailey {Jour. Amer. 8oc. Agron., 6 {191Jf), No. 2, pp. 57-^^).— General and 

 analytical data are presented and discussed. 



[Deficiency of gluten in French wheats], M. Lindet {Bui. Soc. Nat. Agr. 

 France, 14 {1914), No. 5, pp. 563-569) .—A digest of data in which the author 

 maintains that the deficiency of gluten is due to the effect of the climate upon 

 the wheat, particularly during the ripening period, rather than to the effects of 

 cultural conditions. The paper is followed by a discussion. 



Decline in gluten of bread flour, J. P. Wagner {Deut. Landw. Presse, 41 

 {1914), ^^0. 41, p. 515). — A summary and digest of data. 



Physical factors which influence the percentage of wet and dry gluten in 

 wheaten flour, B. H. Kepner {Jour. Indus, and Engin. CJieni., 6 {1914), No. 6, 

 pp. 481, 482). — ^According to the author's conclusions, conditions vary so much 

 that different determinations of wet gluten made in various laboratories are 

 not comparable. 



Thoroughness of mixing affects the percentage of both wet and dry gluten. 

 An excess of water used in making the doughs increases, and insufficient water 

 decreases, the percentage of wet gluten, the percentage of dry gluten being un- 

 affected. 



Up to eight hours the length of time dough is allowed to stand increases the 

 percentage of wet gluten. " High patents, old flours, and low grades are excep-
