378 EXPEEIMENT STATION RECORD. [Vol. 37 



The possibility of preparing a vaccine against human plague from the or- 

 ganism isolated is indicated. 



Pseudotuberculosis in a South American horse, Bbingabd (Rec. M4d. V^t., 

 93 {1911), No. 1-2, pp. 33, 34). — The symptoms, treatment, and post-mortem 

 findings of a case observed at a military depot are reported. 



Tuberculosis, R. A. Craig and C. H. Clink {Indiana Sta. Circ. 60 {1917), pp. 

 8, ngs. 1). — This circular discusses the subject under the topics of occurrence, 

 symptoms, effect on the different body organs, tuberculin testing used in de- 

 tecting tuberculosis, and controlling tuberculosis in cattle and hogs. 



The infection of tuberculosis through air expired during coughing. P. 

 CHAUssfe {Anil. Inst. Fa-iteiir, 30 {1916), No. 11, pp. 61S-6U: fiffS- 2).— Experi- 

 mental data are submitted and discussed in detail, together* with a descrip- 

 tion of the procedure and apparatus used in the study. 



It is concluded in general that the possibility of infection through air ex- 

 pired during coughing is definitely established by the results obtained. The 

 infection depends on the direct inhalation of the fine droplets formed during 

 coughing from the saliva and sputum. The extreme infectivity of tuberculosis 

 is indicated and the great need for a rational prophylactic campaign em- 

 phasized. 



Contribution to the study of delayed or " latent " tuberculous infection, 

 S. Del6pine {Ami. Innt. Patiteur, SO {1916), No. 11, pp. 600-61,2).— Inoculation 

 experiments witJi guinea pigs, using artificially and naturally infected tuber- 

 culous milk, are reported and discu-s.sed. 



Untreated (control) and treated milk (to various temperatures) was used for 

 the injections. The animals which received the untreated milk developed exten- 

 sive tuberculous lesions at the ."^eat of inoculation in two weeks, while animals 

 treated with a much larger dose of the same tuberculous product, previously 

 heated, developed only slight lesious at the seat of inoculation in the course of 

 11 weeks. The postmortem findings were similar to the lesions developed at 

 the seat of inoculation. 



Tubercle bacilli were found still living and capable of a modifii^l patho- 

 genic action after being kept for nearly 5(X) days in milk. It is imlieated that 

 this " supports the view that under certain circumstances tubercle bacilli are 

 still infective after remaining dormant for a considerable period of time." 



Post-mortem and other experimental <lata are submitted in tabular form. 



Types of tubercle bacilli in cervical and axillary gland tuberculosis, A. S. 

 Griffith {Lancet [L(>ndon'\. 1917. J, No. 6, pp. 210-218). — Contiiuiing previous 

 work, the author reports the bacteriological examination of material from 52 

 persons suffering from enlarged cervical or axillary lymphatic glands. The 

 material examined consisted of glands removed l)y surgical operations and pus 

 aspirated from the abscesses or collected from the dressings of the lesions. 



The material from 35 cases produced tuberculosis in guinea pigs, and 

 cultures of the tubercle bacilli were isolated either directly from the original 

 material or through the test animals. Fifteen of the 35 strains were of standard 

 bovine type, 17 of the human type, and 3 atypical. Two of the atypical cultures 

 were obtained from cervical glands, while the third was derived from an in- 

 tramuscular abscess in a patient also suffering from tuberculosis of the cervical 

 glands. 



The experimental re.sults of the three atypical cases are reported in detail, 

 together with a general tabulated summary of statistical data of previous 

 work and that here reporte<l. See also a previous note (E. S. R.. 3.5. p. 576). 



Bovine tuberculosis in the horse, E. Frohnku {Mo>iat.^h. Prakt. Tierticilk., 

 26 {1914), No. 1-2, pp. 5-10). — The clinical data and post-mortem findings of 

 a case are reported in detail.
