(Products of cattle and other animals. It is maintained that the great majority 

 of cases of tuberculous animals are at present produced on not more than 6 

 per cent of the farms of the country. If animals sent to slaughterhouses were 

 jso tagged as to show their origin in all cases, it would be a simple matter to 

 /locate these centers of tuberculous infection and apply suitable means for the 

 complete eradication of tuberculosis. 



The dissemination and control of tuberculosis as illustrated in the bovine 

 species, V. A. Moore (Proc. Ann. Conf. San it. Off. N. Y., 7 {1907), pp. J-'/--'/9).— 

 A historical review is given of the development of knowledge concerning tuber- 

 culosis. Tabular data are presented showing the present status and prevalence 

 of the disease in various parts of New York. Particular attention is devoted 

 to a consideration of the methods of Bang and von Behring in the control of 

 the disease. Von Behring's method is considered as still in the experimental 

 stage. The method has failed in many instances and the duration of immunity 

 is not yet determined with sutticient accuracy. 



The diag'nosis of blackleg, Warringsholz {Berlin. TicrdrztJ. Wchnschr., 

 1908, No. 4, pp. 65, 66). — As a rule, diagnosis in the case of blackleg is an easy 

 matter. Occasionally, however, some difficulty is experienced. In a study of 

 the pathological anatomy of blackleg the author found small gray foci in the 

 cortical layer of the kidneys. These structures were sometimes isolated and 

 sometimes in groups. In the center of each structure a minute quantity of gas 

 is accumulated. Blood clots were found in the heart in every case of blackleg. 



Bacillus pyog-enes bovis and B. pyogenes suis in relation to chronic inflam- 

 mation of the lungs of cattle, H. C. L. E. Berger {VcrgJcichcmlc untcrsuchun- 

 grn iihrr den BaciUiis pyogenes hovis und den BaeiUns pyogenes suis mit 

 heziehung dersellten zu den chronischen hingenentziindungen des rindes. Inaug. 

 Diss. Univ. Bern, 1907, pp. 8.{, figs. 5). — According to extensive investigations 

 of the author in cultivating and testing the pathogenic properties of BaeiUiis 

 pyogenes bovis and B. pyogenes suis, it appears that these organisms commonly 

 occur in chronic cases of broncho-pneumonia of cattle, either alone or associ- 

 ated with other bacteria. B. pyogenes is capable of producing both suppurative 

 and metastatic broncho-pneumonia in cattle. The lesions thus produced may 

 lead to a mistaken diagnosis of tuberculosis, in fact the author claims that 

 cattle in which the lungs are infected with B. pyogenes may react to tuberculin. 



The occurrence and frequency of streptococcic m.aminitis in cows, G. RtJHM 

 {Wehnsehr. Tierheilk. u. Yiehzucht, 52 {190S), Nos. 7, pp. 125-130; 8, pp. 

 I.'i7-152). — It was found possible to detect by the examination of milk the pres- 

 ence of streptococcic mammitis before the disease was apparent from palpation 

 of the udder or from the ordinary methods adopted in milk inspection. The 

 method used by the author in the detection of the disease was that proposed by 

 Crommsdorff for the determination of leucocytes in milk. 



Tick fever in cattle, C. J. Pound {Queensland Agr. Jour., 20 {1908), No. 1, 

 pp. 26-35, pis. 2). — Detailed directions are given covering the technique of pre- 

 ventive inoculation of cattle in the control of Texas fever and East Coast fever. 



Sheep dips, O. Qttibell {Jour. Soc. Chem. Indus., 26 {1907), No. 2.',, pp. 

 1266-1268). — The basis for the present article on sheep dips is the experience 

 of the sheep raisers in the English colonies, particularly Australia and New 

 Zealand, with various kinds of dips in the eradication of scab. 



It was found that the lime-sulphur dip is an undoubted cure for scab, although 

 it sometimes fails to cure other parasites of sheep. Australian and New Zea- 

 land governments, however, finally came to the conclusion that the low price of 

 their wool was to be ascribed to the use of lime and sulphur. Accordingly the
