450 EXPEEIMENT STATION RECORD. 



For the preparation of the casein it is suggested that 50 gm. of powdered 

 casein be added to 100 gm. of freshly slalied powdered lime mixed with a small 

 amount of water in the form of a paste. After this has stood for a short period, 

 an additional amount of water may be added until about a liter of liquid is 

 obtained. This is then added to the Bordeaux mixture and is said to increase 

 its adhesiveness very greatly. 



In order to obtain the best results with these fungicides the authors recom- 

 mend that the nozzle should be held as close to the plants as possible. In 

 spraying grapes for downy mildew the clusters should be well covered with the 

 fungicide. 



Wetting sprays, V. Vermorel (Prog. Agr. et Vit. {Ed. VEst-Centre), 35 

 (1914), No. 32, pp. 180-182). — Gelatin has been found to confer upon sprays 

 containing it an excellent spreading and wetting capacity and perfect adher- 

 ence. Casein proves to be one of the best agents for increasing the wetting 

 capacity of a spray, and to leave almost entirely intact the chemical composition 

 of tbe copper precipitate, which it is adapted to distribute and fix upon the 

 leaves. 



ECONOMIC ZOOLOGY— ENTOMOLOaY. 



Ninth International Congress of Zoology, held at Monaco, March 25-30, 

 1913 (IX. Cong. Internal. Zool, 1913, pp. 928, figs. 178). — The proceedings of 

 the ninth congress are here presented, the papers being given under the fol- 

 lowing sectional headings: Comparative anatomy and physiology (pp. 137- 

 268) ; cytology, general embryology, and protistology (pp. 271-433) ; systematic 

 zoology and habits of animals (pp. 437-541) ; general zoology, paleozoology, and 

 zoogeography (pp. 545-595) ; biological oceanography and plankton (pp. 599- 

 G20) ; applied zoology and parasitology — museums (pp. 623-696) ; entomology 

 (pp. 699-812) ; and nomenclature (pp. 815-915). 



Zoological record, D. Sharp (Zool. Rec, 50 (1913), pp. XII +[1328]). —This 

 volume (E. S. R., 81, p. 56) records the zoological literature relating chiefly to 

 the year 1913, but includes entries for 1901-1912 that were received too late 

 for inclusion in the previous volumes. 



Infection of man with Bacterium tularense, W. B. Wherry and B. H. 

 Lamb (Jour. Infect. Diseases, 15 (1914), No. 2, pp. 331-340, pi. i).— "A case of 

 ulcerative conjunctivitis and lymphadenitis in man is shown to be caused by a 

 minute, capsulated bacterium in all probability identical with B. tularense, 

 which was first discovered by McCoy and Chapin in a plague-like disease of the 

 California ground squirrel] (Citellus heecheyi) [E. S. R., 26, p. 461]. . . . Our 

 findings would seem to indicate that this disease is widespread among rodents. 

 Further, we wish to call attention to the fact that thia recently discovered 

 disease of rodents is apparently sufficiently virulent for gray mice (Miis 

 musculus) to warrant the presumption that it may some day take its place 

 along with B. pestis as a menace to man." 



A new bacterial disease of rodents transmissible to man, W. B. Wherry 

 (P»&. Health Rpts. [U. S.], 29 (1914), No. 51, pp. 3387-3390).— The plague-like 

 disease of rodents previously described by McCoy (E. S. R., 25, p. 249), and 

 found by McCoy and Chapin (E. S. R., 26, p. 461) to be due to a new bacillus 

 (Bacterium tularense), has been discovered by the author and B. H. Lamb to 

 be transmissible to man. 



Two cases have thus far been observed, both at Cincinnati, Ohio, one a meat 

 cutter, the other a farmer's wife. It was suspected that the disease had been 

 transmitted from wild rabbits since they are the chief variety of wild game 

 sold in the markets and because of reports of hunters that wild rabbits in
