Diseased bees and combs infected with a minute pathogenic protozoal 

 parasite, apparently the same as Nosema apis found by Zander and Doflein 

 in diseased bees in Bavaria, H. B. Fantham and Annik Porter {Abs, in 

 Nature [London], 8G {I'.lll), No. 2163, pp. 23Jf, 235). — The infected combs used 

 in the study here reported were obtained from Cambridgeshire and Hertford- 

 shire in March. Since infected bee larvae were found it is thought quite prob- 

 able that this parasite is capable of hereditary infection as is the case with 

 N. bombycis. 



A new proctotrypid parasite of the larva of Anthrenus musaeorum, E. 

 Trani {Atti R. 1st. Incoragg. Napoli, 6. ser., 61 (1909), pp. 19-2.',, pi. /).— This 

 new parasite is doseril)(>d as Lcrlius anthrenivorus.

 Renseig. Agr. [Paris], 10 {1911), No. 2, pp. ISl, 182). — A brief account of 

 Sciitellista cijanea as a parasite of Saissetia (Lccaniutn) olew in France. 



Transmission of spotted fever by other than Montana and Idaho ticks, 

 Maria B. Maver (Jour. Infect. Diseases, 8 (1911), No. S, pp. 322^26).— In the 

 author's experiments Rocky Mountain spotted fever was transmitted to normal 

 guinea pigs by nymphs of Dermaccntor marginatus (from Utah) and Ambly- 

 omma auicricunum that in tlie larval stage had engorged on infected ones, also 

 by nymphs and adults of D. variabilis (from Massachusetts) that had engorged 

 as larvie and nymphs, respectively, on infected guinea pigs. 



Transmission of spotted fever by the tick in nature, Maria B. Maver (Jour. 

 Infect. Diseases, 8 (1911), No. 3, pp. 327-329).— '' Six hundred and flfty-six 

 ticks were collected during the spring months of 1909; 254 of the species 

 Dermaccntor modest us and 402 D. vcnustus, for the purpose of studying the 

 infectivity of the tick in nature. These ticks were found on cows, bushes, and 

 vegetation in the Lo Ix> Valley aud Owl Canyon, Mont., and in the vicinity of 

 Pocatello, Idaho. Fourteen groups were arranged, consisting of 25 male and 

 25 female ticks each. Each group was placed in a new tick-proof sack, with a 

 selected guinea pig of medium size; 9 sacks of Montana ticks (D. vennstus) 

 and 5 sacks of Idaho ticks (D. modestus) were arranged in this way." 



In 2 of the groujis the guinea pig became infected, the ticks of both having 

 been collected from cows in the Lo Lo Valley. 



A contribution to the study of Trypanosoma hippicum, A. Laveran (Bui. 

 Soe. J'atli. E.vot., 4 (1011), No. 3, pp. 16S-175). — Inoculation experiments made 

 by the author show that T. hippicum can not be identified with T. evansi. He 

 thinks it probable that T. hippicum is the same as the form reported by R. 

 Rangel " to be the cause of desrengadera in Venezuela, since their morphology 

 and pathogenicity are quite similar. See also a note by Darling (E. S. R., 23, 

 p. 486).

Shellfish contamination from sewage-polluted waters and from other 

 sources, G. W. Stiles (U. -S. Dept. Agr., Bur. Chem. Bui. 136, pp. 53, figs. 15). — 

 The data reported are based on extended investigations and inspection work 

 carried on in many localities and bacteriological work undertaken to supple- 

 ment such studies. Existing conditions are in many cases criticized but it is 

 stated that the report " is in no sense intended to discredit the valuable indus- 

 tries concerned, but rather to point the way in which the products of these 

 industries may be accepted with greater confidence by the public."
