also been fed on the milk of healthy animals. In October, 
1893, they were injected (the dose being 0.2 per head). Result: 
Healthy, 67 - - (85.03 per cent.) 
Sick, 7 - - ( 8.93 “ “ ) 
Uncertain, 4 - - 1 ( 5.12 “ “ ) 
Total, 78 
Of this last table, which gives 67 healthy animals, or those 
which showed no reaction after the injection of tuberculine, 
only six were offspring of healthy parents. Sixty-one were 
offspring of sick cows or bulls, and after examination I found 
that of forty-two both parents were sick. Of eleven the 
father was healthy and the mother diseased, and of eight the 
father diseased and the mother healthy. 
Of the seven calves shown to be diseased, by the test, we 
found that with one calf only the father, but with six calves 
both parents were tuberculous. 
The calves of the year 1893-94, I have not as yet been 
able to inject; but it shall be attended to shortly, and I have 
good reason to hope, as these animals have been fed on the 
milk of healthy cows, that the result of the investigation will 
be highly satisfactory. 
While the calves of the year 1891, which were fed on the 
milk of non-tested cows, show a percentage of 41.73 per cent, 
diseased and uncertain animals, the years 1891-92 and 1892- 
93, in which milk of healthy cows alone was used, show only 
13.34 and 14.10 per cent, diseased and uncertain calves. 
These figures give a sufficiently abundant reason to be¬ 
lieve that for the extirpation of tuberculosis among the off¬ 
spring, this is the only and safe thing to do. 
After a number of }^ears, when all diseased cows shall 
have been entirely separated, and only the calves of healthy 
cows be raised, the percentage of reacting animals will have 
been reduced to a minimum or will have entirely disappeared. 
The stable in which these animals declared healthy by the 
tuberculine test are kept, makes a very striking and happy 
impression. The well rounded appearance and the smooth 
hair of the animals is striking ; and the tell-tale cough, which .
