    surgeons were not always informed as to the existence of the disease, and that the numbers given above must be considerably below the actual amount in any case. For more ample details in this respect, we have only to consult the Deutsche Zeitschrift fur Thiermedicin, vol. iv. p. 281, vol. vi. p. 136. Adam, in investigating the list of animals killed in the abattoir of Augsburg, arrived at the following results :— In 1879, of 10,988 cattle slaughtered, 321, or 2-92 per cent, were tuberculous;. „ 1880, „ 11,688 „ 262, „ 2-24 „ „ „ 1881, „ 12,500 „ 247, „ 2-00 „ „ According to Drexler, of 55,882 cattle slaughtered at Munich, in 1875, 704, or 1*25 per cent, were affected with Tuberculosis in a very evident manner. Trapp reports that among 11,079 cattle killed in the Strasburg abattoir in 1880, 220, or 1.9 per cent, were tuberculous (this number did not include those slightly affected). For the same year, Mandel found 174, or 3*4 per cent, among 5,105 cattle slaughtered in the Mulhouse abattoir, and in 1879, Strobl and Magin recorded 1,125, or 2-5 per cent, of 44,699. slaughtered at Munich. Taking into consideration the ages of the animals, the 1,125, were classed as follows :— Cattle under one year 2, or 0*2 per cent. ; „ from one to three years 81, „ 7'i „ ; „ „ three to six years 378, „ 33-5 „ ; „ „ over six years 664, „ 59*2 „ The 1,125 tuberculous cattle may be also apportioned in- the following order:— 218, or 1*13 per cent, of 19,284 bullocks slaughtered ; 558, „ 5'30 „ 15,789 cows „ ; 40, „ o-68 „ 5,823 bulls „ ; 28, „ 073 „ 3,803 heifers or stirks „ ; 1, „ o'ooo6 „ 149.971 calves „ From these figures, it results that:— About two per cent, of the cattle sent to the abattoirs of these different towns are affected with Tuberculosis ; The proportion of male to female animals so affected is as. one to three ; The greatest number of animals are more than six years of age;
