886 EXPERIMENT STATION RECORD. 



a normal subject against tuberculosis. Tubercular subjects are the only ones 

 which can be immunized. 



Immunizing against tuberculosis in guinea pigs, G. Deycke and H. Much 

 (Bcitr. KHnilc Tuherkulose, 15 {1910), No. 2, pp. 277-302; ahs. in Internat. 

 Centbl. Gcsam. Tuberkulose Forsch., 4 (1910), No. 12, p. 62S). — The author was 

 able by means of dissolved tubercle bacilli and lecithin to immunize against a 

 following infection with tubercle bacilli. 



Open-air experiments with tuberculous cattle, J. G. Rutherford {Rpt. Vet. 

 Dir. Gen. Canada, 1909, pp. 169-188). — Previously noted from another source 

 (E. S. R., 25 p. 184). 



Control of bovine tuberculosis in British Columbia, M, A. Juli,, A. Knight, 

 and H. H. S. George (Brit. Columbia Dept. Agr., Live Stock Dept. Bui. 32, 1911, 

 pp. 52, figs. 5). — The first part of this bulletin contains the report of the Inter- 

 national Commission on the Control of Bovine Tuberculosis, which has been 

 previously noted (E. S. R.. 25, p. 384). Part 2 deals with bovine tuberculosis 

 in British Columbia and its eradication, and is illustrated by photographs of 

 diseased animals and pathological preparations made therefrom. The text of 

 the contagious diseases (animals) act is also given. 



Scabies (mange) in cattle, E. L. Moore (South Dakota Sta. Bui. 131, pp. 

 203-21.'}, figs. 3). — A popular account describing the symptoms, diagnosis, and 

 treatment. 



A note on the occurrence of pentastomes in Australian cattle, T. H. John- 

 ston and J. B. Cleland (Jour, and Proc. Roy. Soc. N. S. Wales, 44 (1910), pt. 3, 

 pp. 315-318). — The authors record the occurrence of a larval pentastome (Pen- 

 tastomum denticulatum) , the adult of which is knovsoi as Linguatula serrata, in 

 the mesenteric glands of Illawarra cattle suffering from endemic hematuria at 

 Berry, New South Wales. This is said to be the first record of its occurrence in 

 Australia. 



Endemic hematuria (" Illawarra redwater ") in cattle, due to angiomata 

 in the bladder: Its possible relation to pentastomiasis, J. B. Cleland (Jour. 

 Trop. Vet. Sci., 6 (1911), No. 2, pp. 125-133, pis. 2). — "Endemic hematuria 

 (Illawarra redwater) is a distinct entity. It is common in the coastal districts 

 of New South Wales. Evidently the same disease existed near Mt. Gambler in 

 South Australia in 1894. Occasional cases occur in Victoria and probably it is 

 the same disease that exists in Fiji and other Pacific Sea islands. It is char- 

 acterized by hematuria of vesical origin, due to the bleeding from small angio- 

 matous tumors in the bladder. - The condition, as evidenced by the frequent 

 presence of small papillomata and rarely, in long standing cases, by the appear- 

 ance of carcinoma, is due to some foi'm of chronic irritation. Larval penta- 

 stomes, living or calcified, have been found in considerable numbers in the 

 mesenteric glands of all cases examined. They have also been found, but 

 less frequently and usually in smaller numbers, in unaffected animals from the 

 same and other districts. It is possible that the bladder lesions may be caused 

 by the escape of these parasites through the bladder. This is the most probabla 

 etiological cause that has so far presented itself to careful investigation.- The 

 larval pentastomes have not so far been detected in the bladder." 



An experiment in fumigation of ticks, C. W. Howard (Parasitology, 4 

 (1911), No. 2, pp. 164-167). — The experiments here reported were conducted in 

 order to determine whether ships bringing cattle from Madagascar to Portuguese 

 East Africa could be cleaned of the ticks which might have dropped from the 

 cattle and thus be used in the transport of clean cattle for breeding purposes. 



On March 6, 6 species of ticks in different stages, including eggs, unengorged 

 larvae, unengorged nymphs, unengorged and engorged females, and males of
