82 EXPEKIMKNT STATION RECORD. 



Recent evidence as to the identity of human and bovine tuberculosis 



(Join: lloij. A(ji: Sac. Kiujldtnl, i!.i { lOO.'), jip. .W;-.W;J). — A l)ri('f criticiil review of 

 some of the iiion^ iinitortaut literature relatiiif; to this controversy. It is stated tluit 

 m Knghuid tlie laws regarding tiie sale of tulK'rcnlons meat and milk have not heen 

 any less rigidly enforf-ed since the publication of Koch';; address. This staten»ent is 

 made on account of a contrary statement at the Berlin Conference to the effect that 

 great laxity in this regard had been observed during tlie past year or two. 



Tuberculosis of man and cattle, O. Stenstrom (ZtHchr. ThUrmi'd., G {100.i), Xn. 

 4, }>}>. ..'S'J-29I). — The author made a number of experiments in inoculating calves 

 with the si)utum of tul)erculous patients. The results of these experiments are 

 ojjposed to those of Koch, since in certain cases a true infection of tuberculosis with 

 a ti'udency to become generalized Avas i)roiluced. 



Professor Koch, and the danger from bovine tuberculosis, 1'. (iAUNAULT 

 [Le J'rofcsshir Koch, et le peril de la tuherculose bovine. Paris: InMiint luteriidtional de 

 Bibliogrnphie, 1903, pp. A'A'A' + 1062, figs. 10). — In this volume the author presents 

 a brief account of an attempt which he made to inoculate himself in the arm with 

 tubercle material of bovine origin. The greater part of the volume is of a highly 

 controversial nature, in which the author argues against the proposition of the dual 

 nature of tu]>erculo.«is, as proposed by Koch, and seeks to disparage the latter's 

 scientitic attainments, personality, and ethical ])rinciples. A bibliography of the 

 literature relating to this controversy, and ])ul)]ished since the delivery of Koch's 

 address, is appended to the volume. 



The specific nature of serum diagnosis of tuberculosis, P. Eisexbero and 

 E. Keller [CentU. Bukt. u. Par., 1. Alt., S3 (1908), Ao. 7, Orig., pp. 549-5G7).— 

 The literature of serum diagnosis in the investigation of tuberculosis is critically dis- 

 cussed, in connection with a bibliography of 88 titles. The observations made l)y 

 the authors on human patients and numerous investigations on experimental ani- 

 mals indicate that serum reaction can not be depended upon in the diagnosis of 

 tul)erculosis. It was found that the serum reaction was negative in 30 per cent of 

 active cases of tul)erculosis. 



Directions for making protective inoculation against tuberculosis in 

 cattle, E. voN BEHRixtf {Ztschr. Thiermed., G {J902), Xo. 5-G, pp. 328-33.5) .—^oia.^ 

 are given on the best method for selecting cattle for the experiment, numbering the 

 cattle, taking temperature, preparing and measuring the inoculation material, and the 

 technique of inoculation and subseqiient hygienic care of the cattle and stalls. 



Jennerization as a means of combating bovine tuberculosis in agricultural 

 practice, E. vox BEHRixti (7Asc)ir. Thienned., G {1902), Xo. 5-6, pp. 321-327).— 

 The author makes a further report upon the experiments already referred to (E. S. 

 R., 14, pp. 393, 394). It is now considered as demonstrated that cattle vaccinated 

 according to the method of the author are immune against infection with bovine 

 tu])ercle virus of sufficient strength to produce fatal results in control cattle. 



Histological changes after the injection of dead tubercle bacilli, (t. Engel- 

 HARDT {Zlschr. H[ig. u. Infectionskrunk., 41 {1902), Xo. 2, pp. 244-^36).— The present 

 discussion deals with the controversy as to whether the injection of dead tu])ercle 

 bacilli can produce typical tubercles with ultimate caseation of the interior. It is 

 believed that the irritation produced by the dead tubercle bacilli is chiefly chemical 

 rather than mechanical. The reasons for this belief, as stated by the author, are 

 that a desquamative pneumonia is observed in the lungs of experimental animals 

 after injection with dead tubercle ])acilli and that this process closely resembles tliat 

 which occurs in infection by living tubercle bacilli. Tubercles produced l)y dead 

 tubercle bacilli were ol)8erved 80 days after the beginning of their formation, and a 

 fibrinoid substance was not f(iund in the center in any case, and no sign of caseation 

 was observed.

 years, T. Hermanx {Ztschr. Thienned., 6 {1902), Xo. 5-6, pp. 336-368).— On an
