nal, and tlie intrathoracic lesions when present are secondary. Inhalation is 

 probably the commonest natural method of infection in those species (man and 

 cattle) in which the primary lesions of tuberculosis are usually intrathoracic. 

 Naturally-contracted cases of tuberculosis in man and other mammals can be 

 ascribed to infection by ingestion only when the lesions revealed at the post- 

 mortem examination are confined to the abdomen, or when the existing abdomi- 

 nal lesions are recognizably older than those present elsewhere in the body." 



The inhalation of infinitesimal amounts of tuberculous material by 

 bovines and its relation to the production of primary thoracic tuberculosis, 

 P. Chausse (Compt. Rend. Acad. Sci. [Paris], 151 (.1910), No. 22, pp. 1009- 

 1011). — ^The inhalation of very small amounts of powdered tubercle bacilli sus- 

 pended in water produced marked cases of thoracic tuberculosis. 



The relation of fibrosis to tuberculosis, C. T. Williams {Lancet [London'], 

 1910, I, No. 23, pp. 1521-152//, figs. 2; abs. in Internat. CentU. Gesam. Tuderlm- 

 lose Forsch., 5 {1911), No. 3, p. i;22).— There are at least 3 different kinds of 

 fibrosis of the lungs. One is the result of pleurisy ; this is coarser and more 

 vascular, and gives rise to interlobular bands which tend to compress the lung. 

 Another is the result of interstitial pneumonia, specially frequent in those who 

 pursue dusty occupations, also tending to contract the lung and to dilate the 

 bronchi. The third form is . . . tersely described as the past tense of tu- 

 bercle, fibroid tissue encircling caseous masses and old cavities and cutting off 

 blood supply. The author describes the clinical features, which in the first 

 two varieties are the direct consequences of a contracting lung. In the third 

 form there is usually an increase in dyspnoea but an improvement in health 

 in all other respects. An extreme case is described in detail. 



A rare find in meat inspection, Matschke {Ztschr. Fleisch. u. Milclihyg., 

 20 (1910), No. 9, pp. 297, 298; ahs. in Internat. Centhl. Gesam. Tuberkulose 

 Forsch., 5 (1911), No. 5, p. 234)- — An apparently sound cow which had dyspnoea 

 on autopsy was found to have laryngeal tuberculosis. The tuberculous focus 

 was of the size of a walnut, but uneven in shape. 



The author also noted a 14-day-old calf which was well nourished but tuber- 

 culous. 



Tuberculosis of the larnyx in a cow, E. W. Hoaee (Vet. Jour., 67 (1911), 

 No. 1/29, pp. 171, 172). — This is a description of a case of tuberculosis of the 

 larynx in a cow, and includes the symptomatology and pathology. 



Contribution to our knowledge of tuberculosis in the goat, P. Frosch and 

 K. Hertha (Beitrag zur Kenntnis der Ziegcntuberkulose. Inaiig. Diss., Univ. 

 Bern, 1909, pp. 32; Ztschr. Infektionskranlc. n. Hyg. Haustierc, 8 (1910), No. 1, 

 pp. 63-90; abs. in Internat. Centbl. Gesam. Tuberkulose Forsch., 5 (1911), No. 

 5, p. 235). — After reviewing the statistics and the various beliefs of the public 

 in regard to the transmissibility of tuberculosis from the goat by way of the 

 milk, etc., to man, the authors give their results with 8 cases which came up 

 for pathological examination, 6 of which did not show any evidence of tubercle 

 bacilli. 



Animal experiments showed that the 6 cases were tuberculous and infected 

 with the bovine type of bacillus. The patho-anatomical findings, however, 

 varied from the bovine form of tuberculosis in so far that they showed nodules 

 in the various organs which had a great resemblance to echinococcus cysts. 

 These cysts contained a pasty, greenish mass which could be stripped from the 

 capsule very easily. Histologically the nodules showed centrally detritus, and 

 peripherally giant-round and epithelioid cells. The most external stratum 

 consisted of spindle cells. 



Tuberculosis is thought to occur more frequently in goats than in sheep, but 

 less frequently than iu the bovine or hog.
