of a new species of lymphosporidium (Gasperini, 1908)." The parasite is not 

 a protozoan but a blastomyces, namely, Cryptococcus farciminosus. 



" In the United States the disease which was diagnosed as epizootic lymphan- 

 gitis in 1907 has been recognized as being sporotrichosis. Epizootic lymphan- 

 gitis apparently does not exist here. Morpiiologically, by cultures and serum 

 tests, the two diseases can easily be separated. In horses the parasite of sporo- 

 trichosis is very rare in the pus and can rarely be demonstrated microscopically. 



" The sera from sporotrichotic infections give complement fixation with the 

 C. farciminosMs, indicating a relation of the Sporothrix schenckii-beurmatmi to 

 the cryptococcus. This observation is further proof of the vegetable nature 

 of the parasite of epizootic lymphangitis. 



" Human- infections from equine sources of epizootic lymphangitis and sporo- 

 trichosis are rare. It is in the interests of comparative tropical medicine that 

 suspected cases of infections of epizootic lymphangitis should, in future, be 

 carefully investigated bacteriologically and sei'ologically." 



A bibliogi'aphy of 38 titles is appended. 



The relation of animal to human sporotrichosis. — Studies on American 

 sporotrichosis, III, K. F. Meyer (Jour. Amer. Med. Assoc, 65 {1915), No. 7, 

 pp. 579-585, fig. 1 ) . — The conclusions drawn in this third paper are as follows : 



" Spontaneous sporotrichosis of domesticated animals, particularly horses, is 

 very common in certain parts of the United States. Extensive bacteriologic, 

 serologic experiments have proved the identity of the causative organisms in 

 human and animal sporotrichosis. The pathogenicity for human beings was 

 observed in an accidental laboratory infection. The geographic distribution 

 of equine sporotrichosis, which is apparently closely connected with certain 

 telluric and climatic conditions, covers, in two States, the same territories 

 from which numerous cases of human infection have been reported in the 

 last five years. In Pennsylvania equine sporotrichosis as so-called ' epi- 

 zootic lymphangitis ' has been noted in as many as 150 cases annually. Only 

 2 human cases are on record in that State. A careful study of one case 

 suggested at first a contact infection with a sporotrichotic horse, but this 

 assumption could not be proved conclusively. . . . 



" The absence of sporotrichosis among veterinarians and farmers in Penn- 

 sylvania, where equine sporotrichosis is so exceedingly common and so often 

 treated calling forth undoubtedly close contact with infectious material, 

 demonstrates that sporotrichotic infections in man are established by this 

 channel of contact in rare instances only." 



Conglutination in the diagnosis of dourine (trypanosomiasis of the horse), 

 H. Wehrbein (Jour. Inject. Diseases, 16 {1915), No. 3, pp. 461-465). — The 

 author finds that the conglutination method can be used for the diagnosis of 

 dourine but that it is more sensitive to faulty technique and hence more 

 difficult to employ than the usual complement-fixation method. 



The passage of trypanosomes in the milk, A. Lanfranchi (Bui. Soc. Path. 

 Exot., 8 {1915), No. 7, pp. 438-442) .—In the author's experiments with the dog, 

 Trypanosoma brucei, T. rhodesiense, and T. gambiense passed from infected 

 animals in the milk. T. evansi failed to do so. 



Preliminary report on the intrapalpebral tuberculin test, J. R. Mohleb 

 and A. Eichhorn {Jour. Amer. Vet. Med. Assoc., 48 {1915), No. 1, pp. 121- 

 123). — A careful study of the ophthalmic test by the Bureau of Animal In- 

 dustry has shown it to be less ac<?urate than the subcutaneous test. The in- 

 tradermal test employed on the subcaudal fold at the base of the tail has 

 proved more promising.
