ing and treating the disease. Careful and frequent disinfection of the stables is indi- 

 cated for the purpose of preventing outbreaks of this disease as far as possible. 



Tetanus in dogs, DucorRXEAU and P. Jayles {Rev. Vd. Toulouse, 27 {1902), No. 1, 

 pp. 1-5, _fi(j. 1) .—The authors present notes on the subject of tetanus in dogs. It is 

 stated that this disease is probably more frequent in dogs than is usually suspected. 

 In one case a dog affected with tetanus received 200 cc. of artificial serum and a few 

 liours later 5 cc. of antitetanus serum. In this case recovery ultimately took place, 

 although the course of the disease was not rapid and was not immediately affected 

 by the serum treatment. 



The treatment of tetanus, Tenxert (Z^s^/^/■. Veierlndrk., 14 {1902), No. 1, pp. 

 24, 25). — On account of the apparent immunity of dogs to tetanus an experiment 

 was made in treating a case of tetanus in a horse by injections of carbolized serum 

 from a dog. This treatment, however, gave negative results. 



Malaria of dog-s, Nocard and ]\Iotas {Ann. List. Pasteur, 16 {1902), No. 4, pp. 

 257-290, ph. 2). — A general account is given of the symptoms, etiology, and treat- 

 ment of this disease. Two clinical forms are distinguished; an acute form, which is 

 almost always followed by death within a few days, and a chronic form, which may 

 be followed after several days by recovery. The symptoms of both forms are 

 described in detail. An elaborate description of the blood parasite is given. A 

 number of these organisms were found within the red blood corpuscles, but the 

 larger number are free. The organism, from a morphological standpoint, can hardly 

 be distinguished from that of Texas fever, but it is physiologically distinguished by 

 the fact that apparently it will not develop in any other animal than the dog. All 

 dogs whifh recover from the natural attacks of the disease or from artificial inocula- 

 tion are perfectly immune to further attacks. A number of experiments were made 

 in the use of serum obtained from animals which were naturally immune or which 

 had been hyperimmunized. It -was found that the serum obtained from such 

 immune animals exercises a destructive effect upon the organisms in the blood. 

 Virulent blood heated to a temperature of 45° C, or more, completely loses its viru- 

 lence. When heated to a temperature of 44° for periods of 1 hour no effect was 

 apparently produced upon the vitality or virulence of the organism. The same tem- 

 perature maintained for a period of \h hours, however, destroyed the virulence of 

 the blood parasite. 



Rabies, M. P. Ravenel {Pennsylvania Dept. Agr. Rpt. 1901, pt. 1, pp. 511-532, figs. 

 -^).— The author presents a general account of this disease, including its history, dis- 

 tribution, cause, method of invasion, resisting power of the virus, period of incuba- 

 tion, symptoms, means of diagnosis, and treatment. Statistics are presented show- 

 ing the results obtained from the application of the Pasteur preventive treatment 

 on 55,000 persons who had l^een bitten by mad dogs or dogs supposed to be mad. 



Distribution of rabies and an experiment in combating it in the govern- 

 ment of Moscow, A. Stepanov {Arch. Vet. Nauk, St. Petershnrg, 32 {1902), No. 2, 

 pp. 156-178). — Statistics are presented showing the distribution of rabies in various 

 domesticated animals and in man in different parts of Russia, and other countries, 

 from 1883 to the present time. The attempt to eradicate the disease in the govern- 

 ment of Moscow was only moderately successful, and this result is attributed by the 

 author to the ignorance of the people with regard to the etiology and pathogenesis 

 of this disease. 



The reaction of neuroglia to the presence of rabies virus in dogs, Anglade 

 and Chocreaux {Compt. Bend. Soc. Biol. Pari.% 54 {1902), No. IS, pp. 575-577) .—As 

 the result of numerous microscopic examinations for the purpose of determining any 

 constant lesions which might be considered the result of rabies, the authors conclude 

 that the reaction of neuroglia is less rapid in all other diseases than in rabies. In the 

 latter disease the changes in the nervous elements take place very early and are of an 

 acute and generalized nature.
