VETERINARY SCIENCE AND PRACTICE. 609 



According to the author's experience, tuberculosis appears in an epizootic form 

 quite frequently in domesticated fowls. It is believed that the most frequent form 

 of the disease is the intestinal one. It is recommended as a most rational procedure 

 in outbreaks of avian tuberculosis that all the fowls of the flock be slaughtered. 

 This is recommended because it is impossible to detect the disease in the early stages 

 and on account of the difficulty in treating or controlling it as long as the possibility 

 of contagion from infected fowls remains. 



Texas fever. II, Inoculation, G. E. Nesom (South Carolina Sta. Bui. 90, pp. 71, 

 figs. 17). — This part of the author's general discussion of Texas fever is concerned 

 with an account of inoculation experiments and the results thus obtained by the 

 author and other investigators. From a summarized statement of results obtained 

 from inoculation by other investigators it appears that the loss amounted to 7.6 per 

 cent on an average. It is believed, however, that this loss should be reduced to 5 

 per cent. It is recommended that cattle over 2 years of age should not be inoculated. 

 The season recommended for inoculation is late fall and winter. 



Attention is called to the fact that there are many areas south of the quarantine 

 line where no cattle ticks occur. Cattle raised on such areas must therefore be 

 immunized in the same manner as northern cattle before being shipped to tick- 

 infested areas. The effects of inoculation are shown in slight checks in the develop- 

 ment of young cattle, loss of weight, occasional cases of abortion, and other 

 disturbances. It is recommended that cattle be shipped si »uth before inoculation and 

 prevented from becoming infected until the period of inoculation fever is passed. 

 They should then be exposed to gradual tick infestation within 6 months after 

 inoculation. 



A record is given of inoculation experiments carried out by the South Carolina 

 Station on 388 head of cattle. Of this number 256 were northern and 132 southern 

 cattle. One of these died as a result of inoculation fever and 2 from subsequent 

 exposure to tick infestation. The loss in this series of animals therefore amounted 

 to only 0.75 per cent. When the work of immunizing cattle to Texas fever began in 

 South Carolina there were only 2 or 3 herds of pure-bred cattle in the State. Such 

 cattle are now found in almost every county, and the prospects for beef production 

 and dairy industry are believed to be good. 



Milk fever; its simple and successful treatment, J. R. Mohler ( U. S. I>< ■■/>/. 

 Agr., Farmers' Bui. 206, pp. 15, figs. 2). — The name milk fever is considered as some- 

 what inappropriate as applied to this disease since the symptom of fever is fre- 

 quently absent. Parturient paresis is considered a better term. 



The author discusses the symptoms of the disease, post-mortem appearance, prog- 

 nosis and mortality, and various theories regarding predisposition and etiology of 

 the disease. A description is also given of the potassium-iodid treatment recom- 

 mended by Schmidt and also of the new air treatment. The latter is considered as 

 the most simple as well as the most efficacious and harmless method for treating 

 milk fever. The various stages in the perfection of this treatment are noted and a 

 detailed description is given of a simple apparatus for injecting filtered air into the 

 udder. 



The use of atmospheric air in the treatment of milk fever was first adopted by 

 Andersen of Skanderborg, but has recently come into general vogue and has given 

 uniformly satisfactory results. In preventing the development of milk fever it is 

 usually recommended that means be taken to offset the bad results of the plethoric 

 condition of the animal. This may be accomplished by keeping cows on small 

 rations for about - weeks before calving or by administering large doses of Epsom 

 salts for 2 or 3 days previous to this period. The same result may be brought about 

 by abundant exercise. Recently it has been suggested that the occurrence of milk 

 fever may be prevented by allowing susceptible cows to retain most of the milk in 

 the udder for a period of 2-± hours after calving.
