186 EXPERIMENT STATION RECORD. 



The antitoxins employed were those of tetanus and diphtheria. In guinea pigs 

 and rabbits it was found that no diphtheria antitoxin could be demonstrated in the 

 blood of the young, although the antitoxin was present in the mother's blood at 

 the time of parturition. Similar results were obtained with tetanus antitoxin. In the 

 experiments with cattle and sheep it was shown definitely that the antitoxin could 

 be transmitted in considerable quantities in the milk of the mother. In such cases 

 the amount of antitoxin found in the blood of the young and the amount in the milk 

 of the mother corresponded quite closely. 



Annual report on the distribution of animal plagues in the German 

 Empire (Jahresber. Verbr. Tierseuch. Deut. Reiche, 18 {1903), pp. VI +222, pis. 4) — 

 As in previous reports, a general account is presented of the health of animals in 

 Germany and of the prevalence of anthrax, black leg, rabies, glanders, foot-and-mouth 

 disease, pleuro-pneumonia, sheep pox, scabies of horses and sheep, swine erysipelas, 

 swine plague, fowl cholera, fowl plague, cerebro-spinal meningitis, influenza of horses, 

 tuberculosis, and trichinosis. The greater portion of the report is occupied with a 

 detailed account of the distribution of these diseases in different parts of the German 

 Empire. 



Diseases due to streptococci and their preventive and curative treatment, 

 Thomassen {Rev. Gen. Med. Vet., 3 {1904), No. 30, pp. 289-302).— It is believed that 

 in cases of infectious pleuro-pneumonia of horses a streptococcus is associated with 

 the pathogenic pasteurella. Various other diseases of the nature of erysipelas and 

 with similar symptoms are shown to be due to streptococci. Notes are given on the 

 classification of these organisms according to the animal which was affected and 

 according to the nature of the disease produced. In treating the diseases caused by 

 streptococci success has been had in the use of serum. The administration of drugs 

 has not given very satisfactory results except in the case of ichthargan and collargol. 

 The various pathogenic streptococci of man and animals seem to be identical in their 

 pathogenic properties. 



Pathogenic mucors and mucormycoses in animals and man, G. J. Barthelat 

 {Thesis, Univ. Paris, 1903, pp. 128, figs. 13). — In general mycoses may be divided into 

 2 groups according as they are produced by species of Aspergillus or Mucor. 



According to the author's experience, the most virulent species of Mucor are Mucor 

 corymbifer, M. ramosus, M. truchisi, M. regnieri, M. pusillus, Rhizomucor parasiticus, 

 etc. Numerous observations were made on spontaneous cases of mucormycoses 

 affecting different parts of the body of animals and man. As a rule, pathogenic 

 mucors become established more readily in tissues which are already altered in a 

 pathological manner. 



The introduction of spores of mucors into the veins of rabbits, guinea pigs, and 

 chickens, causes the death of these animals after a period which varies according to 

 the quantity of spores inoculated. Spontaneous cases of mucormycoses may be 

 advantageously treated by means of arsenic and iodid of potash. 



Tuberculosis of cattle, D. E. Salmon and T. Smith (U. S. Dept. Agr., Bur. Anim. 

 Indus. Circ. 70, pp. 28).— This is a revision by D. E. Salmon and J. R. Mohler of an 

 article in the Special Report on the Diseases of Cattle (E. S. R., 16, p. 708). 



The frequency of bovine tuberculosis in abattoirs and dairies in the 

 department of Herault, A. Conte (Rev. Gen. Med. Vet., 4 (1904), No. 41, pp. 224- 

 227). — The official reports in France concerning the prevalence of tuberculosis are 

 believed to be somewhat defective and greater thoroughness along this line is recom- 

 mended. Certain French races of cattle appear to be greatly afflicted with tubercu- 

 losis, infection varying from 9.55 to 35.83 per cent. In one instance 199 out of 518 

 animals reacted to the tuberculin test. 



Experiments concerning tuberculosis, III, E. C. Schroeder and W. E. Cottox 

 ( U. S. Dept. Agr., Bur. Anim. Indus. Bui. 52, pp. 95-125). — In continuing their experi- 

 ments along this line the authors found that numerous injections of attenuated cul-
