aud farmers in eleven States in the territory bordering on the quarantine 

 line, being on a larger scale than that previously reported (E. S. R., 27, p. 184)1 



The parasitic diseases of sheep in the Province of Algiers {Rev. ScL 

 [Paris], 52 (1914), I, No. 6, pp. 119, 180). — A discussion of the various ascarids, 

 flukes, tapeworms, and strongjies affecting sheep in Algeria. 



Contribution to the study of necrobacillosis: A specific epizootic form of 

 necrobacillosis in the goat, G. E. Pesadoki {Clin. Vet. iMUan], Rass. Pol. 

 Sanit. e Ig., 36 {1913), No. 18, pp. 816-819; abs. in Vet. Rec, 26 {1914), No. 

 1339, p. 574)- — This article relates to a contagious affection of the claws of 

 goats which appeared in Calabrian districts at the beginning of the winter of 

 1912-13, some 10,000 animals being affected in the course of 2 months. Sheep 

 and cattle kept under the same conditions as the goats and constantly exposed 

 to the infection remained free from the disease. The necrosis bacillus, which 

 gains entry into the organism through lesions in the horn and in the cleft of 

 the claws, is thought to have been the cause. 



Hog cholera, R. A. Ceaig and R. A. Whiting {Indiana Sta. Bui. 173 {1914), 

 pp. 44i-4'i^4, fiffs. 18). — A general account of hog cholera with hygienic pre- 

 ventive measures and treatment, including the preparation and administration 

 of antihog cholera serum. The text of the state law relative to swine diseases 

 is appended. 



Combating hog cholera by vaccination, Pfeiler {Mitt. Ver. Deut. Schweine- 

 siicliter, 18 {1911), No. 7, pp. 103-110). — In this lecture it is pointed out that the 

 disease caused by the filterable virus is more serious than the one produced 

 by the Bacillus suipestifer voldagsen. It probably is a different disease and 

 Dammann (E. S. R., 24, p. 390) according to the author, has satisfied himself 

 to this effect. 



The various facts surrounding the A-accination of hogs with antihog cholera 

 serum and the cause of the disease are discussed with much detail and in a 

 popular manner. 



[Hog cholera], Uhlenhuth {Mitt. Ver. Deut. ScJiweineziichter, 18 {1911), 

 No. 7, pp. 110-113). — While corrosive sublimate and carbolic acid do not kill 

 hog cholera virus in a comparatively short time, a 6 per cent cresol soap solu- 

 tion, or a 1 : 6 or 1 : 20 per cent calcium hypochlorite solution will destroy it 

 within 1 hour. The virus is very resistant to cold but drying at a temperature 

 of 78° C. will destroy it. Heating for one-half hour at 58° does not render it 

 avirulent. When inclosed in fermenting manure the virus dies. 



Hogs which have recovered from an attack of the disease but which are 

 otherwise in an unsatisfactory condition are often found to be virus carriers. 

 The urine of young pigs is especially dangerous and is often the chief cause of 

 the spread of the disease. The secretion from the eyes and nose is very 

 dangerous, for this may be inhaled or may come in contact with the mucous 

 membrane of healthy animals, thus causing the disease. 



The material with reference to the Bacillus suipestifer, which is considered 

 a secondary invader, has been adequately noted from other sources (E. S. R., 

 20, p. 1082; 25, p. 589). See also other notes (E. S. R., 26, p. 785). 



Investigating the infectious diseases of the hog, Pfeiler (Mitt. Ver. Deut. 

 Bchwcineziicliter, 10 {1912), No. 7, pp. 138-145). — This discusses the possibility 

 of using chemotherapeutic agents, especially in the chronic form of hog cholera. 



AVhile the filterable virus as a cause of hog cholera is not doubted, many cases 

 of what seem to be hog cholera do not show the presence of a filterable virus. 

 These cases often have present the Bacillus suipestifer and closely related 

 organisms.
