creas, and mammary glands. The disease attacks not only the epithelia of lining 

 membranes, l)ut also the various glandular epithelia. A number of products of cel- 

 lular degeneration were ol)served in the foci of the disease. The author made a 

 careful examination of this degenerated material and believes that he found sporozoa 

 which may be considered as the parasitic organism of the disease. The various 

 stages of transformation were observed in the cellular elements which were found in 

 the diseased foci along with the supposed pathogenic organism. 



Tlie conditions of commerce in tanned sheepskins and its sanitary regula- 

 tion in the Government of Moscotv, M. L. Blumenfeld {Arch. Yet. Xauk, St. 

 Petershurg, 33 {1903), Xo. 9, pp. 980-991) . — The author discusses the dangers con- 

 nected with the indiscriminate shipment and handling of the pelts of infected sheep 

 and calls attention to the necessity of applying antiseptic treatment to these skins in 

 order to prevent the development of infectious diseases. 



A form of hog- cholera not caused by hog-cholera bacillus, E. A. de Schwei- 

 NiTZ and M. Dorset ( U. S. Dept. Agr., Bnremi of Animal Industry Circ. 41, pp- 4)- — 

 An infectious disease of hogs was studied in southwestern Iowa and later in Washing- 

 ton in hogs which were imported from the original locality. Experiments and obser- 

 vations on this disease show that it is highly infectious, can not be distinguished 

 clinicall}' from hog cholera, but may be reproduced by inoculation with material 

 which contains no hog-cholera bacilli. The period of incubation varies from 5 to 12 

 days. 



The inoculation experiments made by the authors were on pigs which weighed 

 from 15 to 40 lbs., and it was suggested that the period of incubation may be of longer 

 duration in older hogs. Notes are given on the lesions observed in different parts of 

 the body. Rabbits and guinea pigs were found to be refractory to the disease. The 

 isolation of diseased animals and disinfection of infected premises has been found to 

 be efficacious in controlling the disease. 



Swine epizootics and means of repression, Roder {Mitt. Oekon. Gesell. Sachsen, 

 190^-3, pj). 9o-119). — Statistics are given regarding the jjrevalence of swine erysipelas, 

 swine plague, and hog cholera, together with a discussion of the remedies and means 

 of prevention which have proved most successful in combating these jjlagues. The 

 literature of the subject is l)riefly discussed. The author presents an account of vari- 

 ous proprietary and commercial vaccines which have been manufactured for use in 

 preventing the development of swine epizootics. The results obtained from the use 

 of these vaccines by various investigators have differed considerably and further 

 experiments are required to determine their value. 



The bacterial flora of the intestines of hogs, E. Heinick {Berlin. Tierarztl. 

 ]Vrhnsc}ir., 1903, N'o. 9, pp. 141-143). — The author's observations were carried out on 

 a large number of hogs from Avhich samples of the intestinal contents were taken for 

 the purpose of comparing the bacterial content of this material. The results of these 

 investigations are presented in the form of a table and indicate that a large number 

 of known and unknown species of bacteria are conmionly present in a hog's intes- 

 tines. Culture experiments, together with the inoculation of experimental animals, 

 failed to show the presence of pathogenic bacteria except in the rarest instances, and 

 no bacilli of swine erysipelas were found in any case. 



Experimental vaccination with Septicidin in Hungary, J. vox Kukiuevic 

 {Berlin. Tierarztl. Wchnsdir., 1903, No. 6, })p. 79, 80). — In the treatment of swine 

 plague and hog cholera the author found that Septicidin applied at the right time 

 and in the proper manner furnished a good means for preventing the further devel- 

 opment of the disease and exercised a strong immunizing action in animals which 

 were subsequently exposed to the disease. The details of the author's experiments 

 are presented in tabular form.
