 The j)eret>nt;ij;e of reiietiiif,' niiiin.-ils in tliese tests has varied from '2.1 lo 1'.).7

Tuberculosis in the light of recent literature, lli:rss (ZlscJn: \ ficriin'ir/:.. 

 J!) (JUdl). Xo. .1. pp. lil-I'/.i). — Some of the chief in-oi>lems eonnected with the 

 study of tuberculosis -.wv stated and attention called to the wide variatinn of 

 oi)inion which ju'evails on th(>se jioints. It is believed that iiuich study must be 

 devoted to tliis disease before the controverted points will be established. 



The chemical constitution of the tubercle bacillus, J. Arc i.aik and L. 

 Tauis {('onipf. h'riid. Acad. Sci. \l'<iris\, I',', (IDin), So. ■'>. pp. ,i7.s'-..'.s7 ).— The 

 use of petroleum ether in oxtractinjj; tlie fat from tubercle bacilli jj;ave unsatis- 

 factory results and tli(> autlior, therefore, resorted to ether and chloroform. The 

 experiments reiiorted in this ])aiier indicate that the acid resistance of llie 

 lubercle bacillus is not (\uc exclusively to the fat or waxy material contained 

 in the bacillus, but' is a property of the body of the bacillus as a wlioli'. 



Behavior of pus cells toward tubercle bacilli, K. L()WENSTkin {Ztxchr. 

 ll.Ufi. II. /i/fcktionskravk.. .'>.', UDOi;). .\n. .',. pp. Ji2D-Jf50, pi. 1). — It has lonj; l)een 

 uliserved that the leucocytes of animals alTect(Ml with tuberculosis ai-e cai)able 

 of surroundini; tubercle bacilli to a greater or less extent. At times, however. 

 I lie leucocytes seem to lose this jiower. The .-uithor's observations were made 

 on exp(M'imental animals and on pus cells olitained from the sputum of tuber- 

 culous luunan patients. 



It ai>iieiii-s from these exjieriments that the tubei-cle bacilli in a j;iven tubercle 

 acipiire lh(> jiower of resistin.i? the leucocytes in that tul)ercle, and in general 

 the same slalemenl seems to be true for the tubercle bacilli present at any given 

 lime in tl:e tuberculous animal. Such leucocytes, however, when rcMUOved from 

 the body and mix(-d with m.nterial containing tubercle bacilli from some other 

 anim.il show an active juiwer in surrounding the bacilli. The author concludes, 

 Ibei-efore. that tubercle bacilli have the power of gradually acquiring a resist- 

 ance to the leucocytes with which they are more or less in constant contact. 



A leather mask for use in the clinical diagnosis of bovine tuberculosis, 

 L. Or.vi.KA (ZtKchr. I)ifcltio)hslni)ik. ii. II mi. Huu-stinc. 2 {I'.iol), Xo. 2-3. pp. 

 221, 22S, flf/. i).— Considerable stress is laid on the jKissibility of clinical dia.g- 

 nosis of tuberculosis. For this i)urpose the respiratory scmnds must be studied 

 by .luscullation. In older to increase the energy of respiration the nostiMls are 

 closed for a short time, and for this inir])ose a leather mask has been devised. 



Nonreaction of tuberculous cattle to tuberculin, J. Lkiniekes (/>///. Soc. 

 <'< iif. Mrd. ]rf.. S-'i (nxn), No. .'/. /)/*. 00-112). — Detailed clinical notes and post- 

 mortem tindings are given on a numbei- of cases of tiiberculosis in cattle which 

 did not react to tuberculin. The author believes that this tolerance of tuber- 

 lulin is pei-haps of more freqmMit occurrence than has usually been susi)ected. 

 :ind sometimes occurs in animals which show no clinical symptoms of the 

 disease. 



Infection with tuberculosis through the urachus, E. VAmos {Dent. Ticr- 

 iirzll. Wclnischr.. LI il'Jiil). So. .'>. pp. 6'.?, 6"'/). — The evidence for transmission 

 of tuberculosis through the essentiiil reproductive cells is very sli.ght. but a 

 number of i-ases are known where the disease lias been transmitted through the 

 fetal UKMubranes. Attention is called to these cases, and a detailed statement 

 is given of a case in which infection took place in a calf through th(> umbilical 

 cord.
