were distributed in 4,331 herds, 26.55 per cent of this number containing tuberculous 

 animals. According to an earlier investigation 1 of the author's, different breeds of 

 cattle have shown the following percentages of tuberculous individuals : Common 

 Norwegian natives, 0.7 per cent; Telemark, 4.9 per cent; Ayrshire, 15.1 per cent; 

 mixed breeds, 12.4 per cent ; various or unknown breeds, 3.8 per cent. According to 

 the age of the animals, reaction to the tuberculin test was as follows: Under 6 

 months, 1.9 per cent ; 6 months to 1 year, 3.2 per cent; 1 to 5 years, 7.1 per cent ; over 

 5 years, 10.4 per cent; age not known, 7.5 per cent. — F. w. woll. 



Milk from tuberculous cows, C. H. Harrison I Ontario Agr. Col. Rpt. 1S97, pp. 

 147-149). — Experimental tests showed that milk may be tuberculous though the 

 udder is not affected. In one case a cow gave no reaction, but was found upon post- 

 mortem examination to lie generally affected with tuberculosis. One of the cows 

 gave a reaction, but the milk was not affected.

 AM., 24 (1898), Xo. 11. pp. 401-414; 12, pp. 433-441) .—The bacteria of the trachea, 

 bronchial tubes, etc., were examined. 



An active principle in millet hay, E. F. Ladd (Amer. Chem. Jour., 20 1 1S9S), Xo. 

 10, pp. 862-866). — The author reports the isolation of a glucosid from the aqueous 

 extract of millet hay, which on small animals produced the characteristic symptoms
