Notes on a feeding experiment to produce leueoencephalitis in a horse, with, 

 positive results, T. Butler [Jour. ('O)iiji. Mc<l. and ]'(t., J.] {}!>flj\, Xo. S, jip. 49S- 

 501). — An outbreak of this disease in an acute form occurred near Wakefield, Kans., 

 in 1901. From an examination of the conditions surrounding this outbreak it 

 appeared that the disease was due to the use of moldy corn. An experiment was 

 made in feeding samples of this corn to 2 colts. One of the colts died after about 3 

 weeks, and a post-mortem examination showed that the white substance of the cere- 

 brum was nmch softened and broken down. This condition corresponds to those 

 found in spontaneous cases of the disease. 



The duration of the presence of the plague organism when injected into 

 the veins of the horse, Carougeau (Ann. Inxt. I'asteur, 16 (1902), Xo. 11, jtp. 

 842-852). — The author's experiments on this subject indicate that the cultivation of 

 the organism of the plague at a high temperature or its passage through a horse may 

 operate as a means of differentiating the more virulent forms of the bacillus. The 

 less virulent bacilli are more easily destroyed by heat or by phagocytes in the horse 

 than ai'e the more virulent forms. 



Cattle plague in camels, Chegis [Arch. Yet. Xauk, St. Petersburg, 33 {1902), Xo. 

 10, pp. 882, 88-}). — An investigation of this disease among camels showed that under 

 certain conditions these animals may be seriously affected. The period of incubation 

 was found to be 7 days. The disease begins with a fever and is characterized by 

 continued high temperature, weakness, and erosions upon the mucous membranes of 

 the mouth. The course of the disease is about 14 days and the death rate among 

 camels appears to be about 5 per cent. 



Canine distemper, F. T. G. Hobday (Veterinarian, 75. (1902), Xo. 897, pp. 

 482-489). — A numl)er of experiments were conducted to test the value of vaccination 

 in the prevention of distemper in dogs. It was found that 6 pujipies after vaccination 

 were quite as susceptible to distemper as other puppies which had not been vacci- 

 nated, and the distemper Avas as severe in the vaccinated as in the nonvaccinated 

 animals. This method of treatment therefore appears to have little or no value. 



Rabies and dog distemper. Beck {Arch. Wis.^. u. Prakt. Thierh., 28 {1902), Xo. 

 5, pp. 50.'i-509). — A careful study of a number of cases of rabies and dog distemper 

 disclosed the fact that in doubtful cases a differential diagnosis may be reached by 

 inoculation of rabbits; while both diseases may be communicated to rabbits, it is 

 impossible to reproduce dog distemper by inoculation of other animals with the 

 brain of affected rabbits. This point is considered to be of much importance in 

 differentiating between the 2 diseases. 



Fowl sickness, J. F. Marshall {Agr. Jour, and 31in. Pec. IXatal], 5 (1902), Xo. 

 18, pp. 5G5-567). — Fowl sickness, or enteritis, is said to have broken out in many 

 localities in Natal. Notes are given on the symptoms, post-mortem findings, and 

 mean- of combating this disease. 



Trichophytosis, J. B. Kessler (Jour. Amer. Med. Assoc, -39 (1902), Xo. 17, pp. 

 1050, 1051). — Attention is called to the prevalence of ringworm disease among vari- 

 ous animals, especially in cattle, and the danger of transmission to man. A consid- 

 erable proportion of the outbreaks of so-called barbers' itch is believed to be directly 

 attributable to the prevalence of this disease in a mild form among calves. 



Mange, S. B. Woollatt {Agr. Jour, and Min. Pec. [Xatal'], 5 {1902), Xo. 17, pp. 

 .5.j.i-.5.57).— The author discusses the various forms of mange, including sarcoptic, 

 dermatodectic, and symbiotic. Notes are given on the animals affected with these 

 different kinds of mange and on the results of the attack of the disease upon differ- 

 ent animals. In the treatment of mange it is recommended that the scabs or crusts 

 be removed by substances which readily dissolve such material, and that antiseptic 

 dressings of various sorts be then applied to the infested areas. Among the various 

 mange dressings discussed, mention may be made of the following: Kerosene emul- 

 sion dip, containing hard soap, water, and kerosene; lime and sulphur dip; tobacco
