886 EXPEKIMENT STATION RECORD 



The sanitary police and the prophylaxis against hovine tuberculosis, L. 

 Desliens (Rev. G&n. M6d. V^t., 21 {1913), No. 243, pp. 109-123) .—Tids is a 

 discussion of the numerous factors concerned in the prophylaxis against this 

 disease and the elimination of tubercular cattle from dairy herds. 



About the treatment of tuberculosis in bovines with Tuberculosan, T. 

 Fleischhauee (Ueber BehandlungsmetJioden der RiTulertuberkulose mit beson- 

 derer Berucksichtigung des Tuberkulosan-Buroxo. Inaug. Diss., Bern, 1911, 

 pp. 32; abs. in Hyg. Rundschau, 22 {1912), No. 11, p. 1120).— The greater part 

 of this material has been noted from another source (E. S. R., 26, p. 681). 



Histological studies of actinomycosis of the bovine, E. Joest and A. Zumpe 

 {Ztschr. Infektionskrank. u. Hyg. HausUere, 13 {1913), Nos. 1-2, pp. 8-58, pis. 

 5; 3-4, pp. 105-140, pis. 3). — This first paper deals with actinomycosis of the 

 tongue and lymph glands. A bibliogi'aphy of some 54 titles is included. 



Anaplasmosis in cattle in South America, Ligni]&bes {Rev. Asoc. Rural 

 Uruguay, 41 {1912), No. 9, pp. 684-686; abs. in Internat. Inst. Agr. [Rome], 

 Mo. Bui. Agr. Intel, and Plant Diseases, 4 (1913), No. 2, pp. 256, 257).— Ana- 

 plasmosis in South America is said to be a far more serious disease than Is 

 piroplasmosis, most of the infected cattle dying, sometimes after resisting the 

 disease for some weeljs or months. Whether or not the parasite is identical 

 with Anaplasma marginale remains to be determined. It is stated that under 

 natural conditions this Anaplasma is associated with Piroplasma bigeminum 

 and sometimes with P. argentinum. 



Cattle dipping at short intervals, H. E. Laws {Agr. Jour. Union So. Africa, 

 5 {1913), No. 6, pp. 811-819). — " The conclusions to be drawn from these experi- 

 ments are that it is possible to spray or dip cattle every 4 days with an emulsion 

 containing arsenious oxid in the proportion of 1 : 800 without causing any 

 injury to the cattle, and it is also possible to spray or dip cattle every 5 days 

 with an emulsion containing arsenious oxid in the pi'oportion of 1 part emulsion 

 to 600 parts water without any ill effects whatever. Further, with 4-day spray- 

 ing cattle can be kept practically free of ticks, although they may be running on 

 grossly infested pasturage alongside nondipped heavily infested cattle which 

 are kept there to maintain the infestation of the paddock. 



" Spraying at the 5 days' interval gave satisfactory results with the stronger 

 of the 2 solutions, but was not so satisfactory with the weaker dip." 



The tick-killing properties of sodium arsenate, H. E. Laws {Agr. Jour. 

 Union So. Africa, 5 {1913), No. 6, pp. 915-921). — This paper reports experiments 

 conducted in continuation of those previously noted (E. S. R., 20, p. 680). 



It is stated that since very little oxidation takes place in a dipping vat which 

 is constantly in use the strength of the dip in the tank can be maintained by 

 putting cattle through it at regular intervals, thus supplying reducing bacteria 

 to counteract the effect of oxidizing bacteria which do not die out in the tank. 

 There is said to be very little difference between the activity of arsenate of soda 

 at a strength of 1 : 150 and arsenite at a strength of 1 : 300. 



How ticks are killed when cattle are dipped, H. E. Laws {Agr. Jour. Union 

 So. Africa, 6 {1913), No. 1, pp. 49-54)- — The author finds that arsenical dips 

 do not act through being absorbed by ticks through the skin while the animal is 

 passing through the dipping vat or after dipping, but that the host absorbs the 

 poison into its skin and the tick imbibes it with juices extracted from its host. 



Cysticercus ovis, the cause of tapeworm cysts in mutton, B. H. Ransom 

 {U. S. Dept. Agr., Jour. Agr. Research, 1 {1913), No. 1, pp. 15-58, pis. 3, figs. 

 13). — ^This is a detailed report of investigations, a preliminary account of which 

 has been prevously noted (E. S. R., 28, p. 680). A historical summary first pre- 

 sented is followed by a report of life history investigations, a description of the
