Experiments on the treatment of surra in camels, H. E. Ceoss (Mem. Dept. 

 Agr. India, Vet, Ser., 2 (WW, No. 6, pp. 155-198, pi. i,).— "Once sun-a hasl 

 been diagnosed it is not necessary to wait till the trypanosomes again appear 

 in the peripheral circulation before treatment is commenced. The intervals 

 between the paroxysms (1. e., when trypanosonles are present in the peripheral 

 circulation) may extend to several weeks, hence a great deal of time can be 

 saved by commencing treatment at once. ... No case should be considered as 

 cured unless it has been under observation for a year. Relapses may occur 

 after a long interval has elapsed since treatment finished. All cases of camels 

 treated for surra should, therefore, be kept under careful observation. 



" Solutions of soamin above 5 per cent should not be used . . . [as] there is 

 great danger of producing nephritis. Although cures can be obtained without 

 increasing the doses of arsenious acid to the subtoxic dose, as a routine method 

 the doses of arsenious acid should be gradually increased till the subtoxic dose is 

 reached, the principle of the treatment being the sterilization of the tissues. 

 Although the doses of arsenious acid may have been gradually increased to the 

 subtoxic dose, it does not necessarily follow that a cure will result. In the 

 combined method as large doses of arsenious acid can not be given as in the 

 treatment by arsenious acid alone or in the treatment by alternate doses of 

 soamin and arsenious acid. The amount of arsenious acid tolerated by camels 

 varies greatly. In different outbreaks the same percentage of cures will not be 

 obtained, the virulence of the trypanosome varying in different outbreaks. 



" Good feeding is essential." 



Diseases of swine, K. Glassek (Die Krankheiten des Schweines. Hanover, 

 1912, pp. ¥111+296, i)ls. 10, figs. 22). — This work has especial reference to the 

 iufectious, invasive, and intoxicative diseases of the pig. It is recommended 

 for veterinarians and students of veterinary medicine. 



Hog' cholera and the production and use of hog-cholera serum, D. E. 

 Salmon (Anier. Vet. Rev., 45 (1914), No. 2, pp. 178-195). — A concise critical 

 discussion of some of the early work of Smith, Dorset, and McBryde relative 

 to hog cholera. It also contains observations in regard to the production 

 of antihog-cholera serum (with reference to potency, contamination, and mix- 

 ing virulent blood from different sources) and methods of using it (develop- 

 ment of abscesses in vaccinated hogs, serum-alone method, and serum-simul- 

 taneous method). 



Hog cholera and its control, R. Graham and E. W. Mumma (Kentucky 8ta. 

 Bui. 182 (1914), pp. 167-251, figs. 25).— Following the introduction to this bulle- 

 tin (pp. 1G9-1T5) in which J. H. Kastle presents a brief review of hog cholera 

 serum work at the station since 1910, the authors give a general account of 

 hog cholera and means for its control, particularly as relates to the use of 

 antihog-cholera serum. Of 102,087 hogs vaccinated in 2,307 herds during the 

 years 1911, 1912, 1913, and to July 1, 1914, 86,647 were reported upon, of which 

 90.59 per cent lived. 



The regulations of the state live stock sanitary board are appended. 



About the practical value of serum protective vaccination against hog 

 cholera, :\r. Zingle (Berlin. Ticrdrztl. Wchnschr., 30 (1914), No. 7, pp. 119- 

 121). — This describes an outbreak of acute hog cholera which occurred amongst 

 young and old pigs and in which the value of antihog-cholei-a serum from 

 highly immunized animals was demonstrated. In most cases when the animals 

 were markedly affected with the disease passive immunization did no good. 



A contribution to the shoat typhoid question, H. Weidlich (Berlin. Tier- 

 ur:^U. Wchnschr., 30 (1914), Nos. 5, pp. 73-76; 6, pp. 89-91, fig. i).— In view of 

 the controversies which have arisen as to whether Bacillus voldagscn has any 

 relation to hog cholera (E. S. R., 24, p. 390; 27, p. 888; 28, p. 183), a biological
