company with the entire herd and stood the test satisfactorily. 

 Even in the present series of tests, this cow (with one exception) 

 never rose more than two degrees above her initial temperature 

 taken when that particular test was started, and she only 

 rose nine-tenths of a degree above io2F.°, which may be set down 

 as the normal standard temperature of a cow in full milk, highly 

 fed and kept indoors. Taking into account the variations in 

 healthy cattle from one time of the day to another, this rise of 

 less than one degree above the general standard implies nothing. 



The exceptional case was on Nov. 9th and loth, when Mabel's 

 temperature rose to 104° and that of the Short- Horn grade to 

 104.3°. Taken by itself this test might have been misleading, 

 but in connection with six other tests (in case of Mabel seven) 

 made both before and after this, with the same dose of tuberculin 

 and with no such resulting rise, it can safely be set down to acci- 

 dental conditions. The real cause was not clearly made out, but 

 it is probable that it was chargeable on exposure in a cold draught. 

 Both cows stood on separate ranges close to the east door of the 

 barn, through which the manure had to be forked out, and with a 

 cold east wind entering by that door, and blowing on cattle that 

 had been shut up in a warm building over night, a slight chill 

 was to be expected. 



The Jersey, Daisy, never rose above the normal standard of 

 102°, excepting in the first test and then only to 102.3° — too lit- 

 tle to furnish even a suggestion of tuberculosis, no higher than 

 we find in many well fed healthy cattle. 



The Holstein, Belva, on two occasions rose to 102.5°, half a de- 

 gree above the normal standard, but which is often attained to in 

 health, and apart from the tuberculin test. Moreover on five other 

 tests both before and after these she did not show a rise over 102° 

 so that the less suspicion should arise from this insignificant ele- 

 vation. 



The Devo7i grade coiv in different tests had her temperature ele- 

 vated to 102° and on one occasion to 102.6°, a little more than 

 half a degree above the normal, and which, as already said is 

 found in the healthiest cows. 



The Short-Horn grade had a fever temperature on one occasion 

 apparently from a chill as already referred to. In her first test it
