Tricresol in the treatment of parturient paresis, S. Buenton [Anicr. Vet. liev., 

 ;%■ {i;i<)3), No. J2,pp. 1124, It,.'')). — The authdi'luis liad good mikh'chh ill treating cashes 

 of this disease with a mixture containing 2 gni. of tricresol and glycerin in a quart 

 of sterilized water. This mixture is injected in equal quantities into each (juarterof 

 the udder. In the majority of cases 1 injection is all that is required, hut the treat- 

 ment may be repeated at intervals of 6 to <S hours if necessary. 



Contagious vaginitis in cattle, H Thiekky [.four. Agr.Pntl., n. .'<er., 5 (lUOS), 

 No. 2.i, pp. 7. "i7 -7 39). — The symptoms and distribution of this disease are briefly 

 noted and a short description is given of its various forms. Spontaneous recovery 

 takes ])lace in some cases after 4 to 5 weeks. Injections of j)ermanganate of potash 

 were effective in controlling the disease, but are considered rather diflicult to apj)ly. 

 The simplest and most economic method oi treating the disease is ])elieved to be 

 found in quarantining and retiring from service all infected bulls. 



Hygienic conditions of parturition as a prevention of calf diseases, M. G. 

 DE Bruin {Fortschr.Vet. Hyg., 1 {1903), No. G, pp. ISl-lSa).— The author briefly 

 describes the natural provisions by which the calf is protected against infection dur- 

 ing the process of parturition. In order to prevent infection of calves it is suggested 

 that attention be given to the following matters: Promotion of a normal course of 

 parturition, prevention of contact of the umbihcal cord with soil or other substance, 

 and rapid drying of the umbilical cord. 



Blackleg and malignant edema, from tlie standpoint of differential diag- 

 nosis, (t. Gutzeit {Fortuchr. IW. Hyg., 1 {1903), No. .5, pp. L57-l-')9). — Blackleg 

 appears to be confined to certain districts which are permanently infected, while 

 malignant edema may appear anywhere without relation to particular districts. 

 The clinical symptoms of both diseases are very similar, but the pathological anatomy 

 furnishes a surer basis for differential diagnosis. Conspicuolis differences can also 

 be demonstrated bj^ cultivation of the imthological organisms. Finally, the surest 

 method of differentiating between these diseases is found in inoculation of experi- 

 mental animals. Rabbits and mice are not susceptible to Ijlackleg, but readily 

 become infected with malignant edema. 



Psoroptic scabies in cattle {Bui. il/(',sso»r/ State Bd. Agr., 3 {1903), No. 5, pp. 

 13-16, figs. 2). — Descriptive and biological notes on the mite which causes this dis- 

 ease and a short account of symptoms and treatment. The author recommends dip- 

 ping in creolin, chloro-naphtholeuin, or the lime and sulphur dip. 



The cattle tick and its relation to the cattle industry of North Carolina, 

 T. Butler {BuI. North Carolina State Bd. Agr., 34 (1903), No. 5, pp. 28, figs. 2) .— 

 Notes are given on the appearance, habits, and life history of the cattle tick and on 

 the losses due to its attacks upon cattle. In exterminating the tick it is recom- 

 mended that cattle, horses, and mules be kept out of tick-infested pastures after 

 September 1, that such pastures be divided by fences with a tight board along the 

 ground so as to allow alternation of grazing. Where it is practicable it is also rec- 

 ommended that infested pastures be burned over. 



Notes are also given on the Federal quarantine line. State quarantine line, and the 

 hardships which cattle raisers of the State suffer on account of these restrictions. 

 Attention is called to the fact that much better conditions for cattle raisers would 

 exist if ticks were exterminated. Notes are also given on the immunization of cattle 

 to Texas fever, and a brief account is presented of the symptoms of this disease. 



Trichodectes geomydis expansus, and the ticks of Mexico, A. Duges {Mem. y 

 Rev. Sor. Cieiit. "Antouio Alzate," IS (1902), No. 4-o, pp- 185-195, figs. 35).— A descrip- 

 tion is given of Trichodectes geomydis, and notes are given on its life history. It lives 

 as a parasite on Geo my s mexicanus. Brief notes are also presented on Amhlyomma 

 cajanncnse, Ornithodoros megnini, 0. turicata, and the common cattle tick. 



Wasting diseases caused by animal parasites, ^V. A. Knight {Amer. Vet. Rev.,
