tina. The ticks belonging to this family and also the genus Argas are described 

 with notes on their habits, life history, and economic importance. 



The blood parasite which causes Texas fever and is carried by cattle ticks 

 is discussed with particular reference to its proper name. The author believes 

 Ihat this should be Babesia hovis. Analytical tables are presented for the 

 identification of various species of the Ixodidse. A tabular list is also given 

 showing the name of the tick, the name of the discoverer, the host, and locality. 

 The genus Boophllus is retained and the common cattle tick is referred to under 

 the name B. aiDiiilatiis. The form found in Argentina may be a variety of the 

 typical species. 



From the literature of the subject and also from experiments carried out 

 by the author data are presented regarding the reaction of ticks toward light, 

 tobacco fumes, sarnol, and other substances. The subject of insecticides and 

 dips for the destruction of ticks is presented with particular reference to Amer- 

 ican experiments in this field. It is held that ticks may be exterminated by a 

 suitable system of pasture rotation. 



Experiments with bees, S. A. Bedford {Canada E.rpt. Farms Rpts. 1905, 

 pp. S'l'). S.'/il). — Last year the bees were not placed in their winter quarters until 

 November 28. A corner of a cellar under a residence is used for this purpose, 

 being partitioned oft", kept dark, and the temperature regulated as uniformly as 

 possible. The amount of honey consumed during the year was G to 28 lbs. per 

 colony with an average of li lbs. A test of the importance of ventilation in 

 wintering bees indicated that it. is not necessary to have a current of air passing 

 through the hives provided the cellar is kept well ventilated. 



A bee scale, C. Deche (Apicultenr, 50 {1906). No. /,. pp. llfS. If/J,, fig. 1).— 

 A description is given of a simple scale weighing only 30 lbs. and capable of 

 easy transportation from place to place. The scale is especially adapted for 

 weighing colonies of bees, Imt may also be used for other purposes. 



Beehives and bee keepers' appliances, P. N. Hasluck {London: Cassell 

 d Co., Ltd., 1905, pp. 160, figs. 155). — The present volume contains a digest of in- 

 formation relating to beehives and other appliances necessarj^ in bee raising. 

 The material of the volume is arranged in chapters on bar-frame hives, temporary 

 hives, tiering bar-frame hives, stocking beehives, permanent and temporary 

 observatory hives, inspection case for hives, queen-rearing hive, bee smokers, 

 honey and wax extractors, and miscellaneous appliances for bee keepers. The 

 various devices described in the volume are well illustrated. 



FOODS— HUMAN NUTRITION. 



Some forms of food adulteration and simple methods for their detection, 

 W. D. BiGELow and B. J. Howard {V. 8. Dept. Agr., Bur. Cheni. Bui. 100, pp. 

 59). — The common forms of adulteration met with in baking powders, alcoholic 

 antl nonalcoholic beverages, canned vegetables, cocoa, chocolate, coffee, tea, con- 

 dimental sauces, dairy products, flavoring extracts, fruit products, meat prepara- 

 tions, and other food products are described and discussed, and data summarized 

 in tabular form showing the extent of adulteration as determined by American 

 Investigators. 



Sugar, flour, and cereal breakfast foods, it is stated, are i>ractieally free from 

 adulteration. " The rumors which have been circulated from time to time 

 that arsenic and other poisonous substances are used in breakfast foods have 

 been entirely without foundation. . . . 



" There is an impression in some quarters, unfortunately, that flour is 

 adulterated with ground gypsum or other mineral matter. It is also believed 

 by many that alum is used for the purpose of whitening bread. It may be 

 said, however, that these forms of adulteration are not practiced in this
