284 EXPERIMENT STATION EECORD. 



Statistics given regarding the localization of the disease in different quarters 

 of the udder show that in a total of 115 cases the disease was confined to one 

 quarter in 47 per cent, to 2 quarters in 33 per cent, to 3 quarters in 13 per cent, 

 and that all 4 quarters wei'e involved in only 7 per cent of the cases. One or 

 both hind quarters were diseased in 91 per cent, and one or both fore quarters 

 in 50 per cent, of the cases. The disease was confined to the hind quarters in 

 50 per cent, and to the fore quarters in 9 per cent of the cases. 



The author concludes that the primary lesions in the gland are embolic, and 

 started by bacilli which have been admitted to the blood stream from some 

 tuberculous focus in the lungs. In regard to their source the reviewer says 

 " when account is talien not only of the much greater frequency of lesions in 

 the hind quarters, but also of the further fact that the supra-mammary 

 lymphatic glands (which overlie the hind quarters) often show lesions which 

 are obviously older than those in the udder tissue, and that the primary inva- 

 sion of the latter is usually at the upper part of a quarter, the only permissible 

 conclusion is that infection of the udder usually takes place by way of the 

 lymphatic vessels." 



Septicemia hemorrhagica in cattle, A. W. Curlewis {Jour. Dcpt. Agr. Vic- 

 toria, 7 (HJOD), 7\o. 2, pp. 91-93). — During the last few months considerable 

 mortality in cattle has occurred in parts of A' ictoria from a form of septicemia 

 hemorrhagica known in some countries as buffalo disease. Seven cases are here 

 reported. 



Parasitic diseases of sheep, D. F. Luckey {Missouri Bd. Agr. Mo. Bui., 6 

 {J908), No. JO, pp. 3Ji, figs. 17). — Nearly all the losses of sheep are said to be 

 caused by parasites, which are here briefly considered. 



Experimental test of treatments for worms in sheep at Glen Innes Experi- 

 ment Farm, M. Henry and J. D. Stewart {Agr. Gaz. N. 8. WaJcs, 19 {1908), 

 No. 12, pp. 981-985). — "The results obtained would seem to emphasize again 

 the fact that the giving of good feed and salt is the best treatment to apply 

 to sheep affected with worm infestation of any description; that while stomach 

 and intestinal worms can be dislodged fairly readily, bronchial parasites can 

 be so only with .great difficulty ; and that stock owners must look to preventive 

 methods rather than to 'cures' to save themselves from loss from this cause." 



Hemlock poisoning- in pig's, I. Calinescu {Arhiva Vet., 5 {1908), No. Jf-5, 

 pp. 229-231; ahs. in Vet. Ree.,21 {1909), No. 1076, p. 550).— The author reports 

 an outbreak of a fatal disease in swine found to be due to the eating of the 

 stems and leaves of the large hemlock {Coniuni maculatum). 



Horse sickness and its prevention, PI. AVatkins-Pitchford {Natal Agr. 

 Jour., 11 {1908), No. 12, pp. 1543-1558; Agr. Jour. Cape Good Hope, 3', (1909), 

 No. 1, pp. 22-25). — This is a paper read before the Annual Conference of the 

 Intercolonial Agricultural Union in which the author presents a general 

 account including the history of the disease. 



The disease is essentially South African. By a process of elimination the 

 author attempts to prove that the infection which is due to a filteral)le virus 

 is transmitted by insects. Experiments are reported in which horses protected 

 from mosquitoes by the screens of gauze netting remained unaffected while 

 near-by unprotected horses were attacked by the disease. The use of smoke 

 smudges to keep away insects has -given considerable protection from the 

 disease. 



The immunity of mules against horse sickness, A. Tiieiler {Transvaal Agr. 

 Jour., 7 {1909), No. 2(), pp. 175-183). — The author here reviews the results 

 obtained from inoculations of mules against horse sickness, these being first 

 introduced into practice in November, 1905.
