NOTES. 499 



M. P. Eavenel, of the University of Wisconsin, discussed some aspects of the 

 tuberculosis problem. He cited statistics which showed that human subjects 

 under 1 year of age are more susceptible to tuberculosis than when older, aud 

 that a great danger lies in the transference of this disease from bovines to 

 infants through the agency of milk. W. A. Evans, professor of hygiene in 

 Northwestern University, also spoke on milk as a factor in the transmission 

 of disease. 



As chairman of the special committee on veterinary college investigations, 

 D. M. Reynolds reported a list of the schools acceptable to the association, with 

 recommendations for future work. N. S. Mayo, for the special committee on 

 advertisements of veterinary remedies, reported that its activities had been 

 confined chiefly to dissseminating information in regard to the composition of 

 many of the so-called fraudulent veterinary remedies which are being exten- 

 sively advertised. The heads and other officers of agricultural colleges and 

 experiment stations were asked to use their influence in checking this traffic 

 and to refrain from giving testimonials to companies exploiting goods of this 

 character. Reports were also submitted by the committee on agricultural 

 college investigation and the committee on the revision of veterinary anatomical 

 nomenclature, from the delegates to the Farmers' National Congress, the Inter- 

 national Congress on Hygiene and Demography, and the National Association 

 for the Study and Prevention of Tuberculosis, and on the progress made by the 

 International Tuberculosis Commission. 



The report of the special committee on glanders, given by E. B. Ackerman, 

 dealt with the study of modern diagnostic methods. The opsonic index and 

 conglutination test were considered laborious and impracticable, and the pre- 

 cipitation test unreliable. An agglutiaation value of over 1 : 1,000 is regarded 

 as indicative of glanders, but as high agglutination titers are obtained only in 

 the acute form of the disease, it is advisable to carry it on in combination with 

 the complement fixation method and to diagnose the disease on the basis of both 

 tests. The ophthalmic test was recommended as the one which would meet all 

 the requirements for the veterinarian, and consequently as the test which 

 should be utilized by state and federal authorities in their activities against 

 this disease. J. R. Mohler and A. Eichhorn reported the results of their investi- 

 gation of immunization tests with glanders vaccine, and B. T. Woodward ar- 

 raigned the puljlic drinking trough for the dissemination of glanders among 

 animals. 



A symposium on forage poisoning, or so-called equine cerebro-spinal menin- 

 gitis, was participated in by the sections on sanitary science and police and 

 veterinary medicine. The view was taken that the disease is either caused by 

 spoilt fodder or that certain enzyms are present which under certain conditions 

 will liberate hydrocyanic acid. 



In a paper on the tuberculin testing of cattle and hogs, C. M. Haring. of the 

 California Station, pointed out that the intradermal method can be more sat- 

 isfactorily applied to young calves and wild range cattle than the usual subcu- 

 taneous method. It was found especially useful in testing cattle during the 

 hot seasons in the interior valleys of California, where the subcutaneous reac- 

 tion was inferior in point of time, material used. etc. Under dairy conditions 

 the intradermal test equals the subcutaneous method providing a 5 per cent 

 solution of a tuberculin precipitated by alcohol is used. Since neither the intra- 

 dermal nor the subcutaneous method will detect all the cases of tuberculosis, 

 it is advisable to apply the two tests at the same time. Tuberculins containing 

 5 per cent or more of glycerin can not be used for the intradermal test. 



S. H. Gilliland and C. J. Marshall reported an investigation in which immunity 

 was produced in cattle by intravenous injections of nonvirulent, human type
