^Y'*. .^, pp. 343, 846). — Statistics are presented showing the prevalence of sheep scab 

 in different districts and in different herds. The following regnlations have been 

 adopted for the control of this disease in 1902: All sheep are to be inspected between 

 January 1 and April 1 in order to determine whether or not they are infected; the 

 inspection must be made without previous announcement; scabby sheep are to be 

 treated as soon as possible after shearing, according to the method of Frohner. Sheep 

 are first to be treated for a, period of 3 or 4 days on the scabby spots with a mixture 

 of 1 part English creolin, 1 part alcohol, and 8 parts green soap. They are then to 

 be washed, and then dipped for 2 minutes in the 2i per cent aqueous solution of 

 creolin, after which the scabby spots are to be brushed for about 3 minutes and the 

 sheep to be again dipped in the solution. The treatment is to be repeated in 1 week. 



Treatment of sheep scab, Frohxer (Deut. Tierdrzll. Wrhnschr., 9 {1901), No. 

 38, pp. 385-387). — The results obtained by treatment of this disease according to 

 Fri'ihner's method are discussed in a critical manner. It is believed that the failures 

 from the use of this method are due to the creolin. Of 3,866 sheep treated for scab 

 by this method in 1900, 3,500 were later slaughtered on account of the development 

 of scab which appeared to be unchecked by the treatment. It is believed that the 

 treatment would be much more effective if applied before shearing, since the solu- 

 tion would be thus held longer by the wool and the scab mite would l:>e subjected to 

 a longer exposure to the insecticide. 



Heart"water in sheep and goats {Agr. Jour. Cape (jood Hope, 19 {1901), Xo. 5, 

 pj>. 302-314, fi(j>(. 2). — Experiments made by the Colonial Veterinary Department 

 indicated that the disease known as heartwater was not connnunii-ated by ordinary 

 sources of infection. It was suspected that some species of tick was concerned in 

 the transmission of the disease from animal to animal. The entomological depart- 

 ment made experiments along this line and demonstrated conclusively that the bont 

 tick {Amblyomma hebrieum) was an agent in the transmission of the disease. 



Further experiments were made in the artificial communication of the disease ])y 

 means of ticks. It was shown that even a limited infestation In- young bont ticks 

 which fed during their larval stages on the diseased animals will produce the disease 

 in a severe form in susceptible animals. An excessive infestation l^y other ticks 

 which have been allowed to feed on diseased animals does not produce the disease 

 in susceptible animals. 



Inoculation against swine erysipelas, Kt?HX.\r {Milcli Ztg., 30 {1901), No. 24, 

 pp. 372-375). — The nature and cause of this disease are discussed in a general way. 

 The author describes the usual symptoms of swine erysipelas and gives an account 

 of experiments which have thus far been conducted in perfecting a protective serum 

 for inoculation and in devising a convenient and practical method for making the 

 inoculation. 



liympliangitis saccharomycotica equorum, A. Dedyilin (Arcli. \'et. Ncmk, St. 

 Petersburg, 31 {1901), No. 9, pp. 814-822). — This disease is known under a number 

 of names, including African glanders, trembling lymphangitis, epizootic lymphan- 

 gitis, and curable farcy. The symptoms and pathological changes produced by this 

 disease are described in detail. In experiments with remedies for treatment of the 

 disease the author obtained different results, according to the susceptibility of the 

 affected horses and according to the virulence of the infection. In some cases all 

 forms of treatment were unsatisfactory, while in others fairly satisfactory results 

 were obtained by a combination of internal and external remedies. The colloidal 

 silver preparations were given in intravenous injections in doses varying according 

 to the nature of the diet. For external application upon ulcerated areas, caustic 

 potash, iodin with glycerin, corrosive sublimate, najihthaline, and iodoform gave 

 fairly good results. 



Observations on skin disea.ses which have appeared in cavalry horses in 

 the region of the loins and under the saddle since the introduction of the
