1064 EXPERIMENT STATION RECORD. 



A test was made of a large number of substances to determine their value as 

 repellants for mosquitoes. It was found that formalin, oil of cloves, bergamot 

 oil, cinnamon oil, oil of peppermint, and various other essential oils had this 

 effect to a considerable degree. In experiments in the destruction of mosquito 

 larvie and pupie ia water, it was found that green schist oil as well as petro- 

 leum and B-ordeaux mixture are of considerable value for practical use. Good 

 results were also obtained from the use of a proprietary antiseptic, depending 

 for its action largely upon the presence of formalin. 



Glossina palpalis as an agent in transmitting' trypanosomiasis, L. Cazal- 

 Bou (Cuiiipt. Rend. Acad. Sci. [Paris], 1J,S {1906), So. 12, pp. 435-^37).— In 

 experiments with dogs and cats it was found that G. palpalis naturally infected 

 with tryiKinosomes was capable of transmitting the infection to these animals. 



Some disease-carrying insects, ('. E. Chambers {Clriiisoii Ayr. Col. Ext. 

 Work, 2 (1906) ~So. 5, pp. IS, figs. .5). — A brief account is given of the habits and 

 life history of the common house mosquito, malarial mosquito, yellow fever 

 mosquito, and house fly, with special reference to their agency in carrying dis- 

 eases and to means of combating them. , 



Ticks in the transmission of diseases, W. DiiMTz {Ber. Henckenb. Naturf. 

 Gcscll.. 1000. pp. 39-52). — In this discussion particular attention is given to 

 Iwodes riclnus, Boophihis aiiinikitiis. RhipiecphuUtx appcndirnJutas, Anjas pcrsi- 

 cus, and Ornithodurus inouhata. 



A new type of sarcoptic mite parasitic on pupiparous diptera, E. Sergent 

 and E. L. Trouessart (Compt. Rend. 8oc. Biol. [Paris], 62 {1907), So. 10. pp. 

 ■fi3--'i'45, pg. 1). — In Algeria, the domestic pigeon is infested with a parasitic 

 fly known as Lyncliia maiira. This fly is at times apparently parasitized by a 

 mite described as a new genus and species under the name Myialgcs anclwra. 

 Since this family of mites is apparently confined to warm-blooded animals, it 

 is suggested that the mite may spend the greater part of its existence on the 

 pigeon and may merely deposit its eggs upon the parasitic fly. 



FOODS— HUMAN NUTRITION. 



Poods and their adulteration, II. W. Wiley {Philadelphia: P. Blakiston's 

 Son d Co., 1907, pp. XII +625, i)ls. 11, figs. 86).— Jn this volume, which is 

 designed for manufactures, consumers, physicians, and sanitarians, as well as 

 for the general reader, the author has summarized a large amount of data 

 regarding the methods of preparation and manufacture of animal and vegetable 

 foods, their nutritive value, standards of purity, regulations for inspection, 

 simple tests for adulterants, effects of storage, and related questions. Among 

 the special subjects are meat and meat products, poultry and eggs and game 

 birds, fish foods, milk and milk products and oleomargarine, cereal foods, vege- 

 tables, condiments and fruits, vegetable oils and fats and nuts, fungi as food, 

 sugar, sirup, confectionery and honey, and invalids' and infants' foods. 



In the form of appendixes, extracts are given from the national laws relating 

 to ]>ure food, as well as rules and regulations for the enforcement of the laws, 

 amd official standards of purity. The author calls attention to the fact that al! 

 opinions regarding adulterations, misbranding, nutritive value, and wholesome- 

 ness are individual expressions and are not to be considered in any other 

 manner. 



The volume as a whole constitutes a very interesting and valuable reference 

 handbook and discussion of food and food adulteration.
