6. Cattle taken from pastures nmst not be enclosed in a hot, 

 stuffy stable. While they must be tied up to allow of the tem- 

 perature being taken at short intervals, coolness and ventilation 

 should be secured in summer by a sufficient air space and the 

 requisite ventilating openings. 



7. Exposure to cold draughts between open doors a?id windows, 

 or to ivet or chilly blasts out of doors should be careftdly guarded 

 against. A chill proceeding from any source and alike in the 

 presence or absence of tuberculin causes a rise of the internal 

 body temperature. 



8. Heavy cows 7inaccustomed to stand on hard boards may 

 have a rise of temperature in connection with resulting te?ider?iess of 

 the feet. One must avoid hard floors on the day of the test or 

 make examination of feet and allow for attendant fever. 



9. Omission of the previous milking or a chaiige of milker and 

 co7iseque?it retention of part of the milk will raise the temperature 

 of a nervous cow, and in careless hands secure an erroneous con- 

 demnation. 



10. Privation of zvater at the regular time will ofte?i cause rise 

 of te?nperature especially when on the dry feeding of winter. I 

 have seen a general rise of two degrees and upward from the 

 delay of watering for a single hour, while after watering the 

 temperature went down to the normal and remained so. Water 

 always tends to a temporary lowering of temperature but in the 

 presence of tuberculosis it soon rises again. 



11. Change of food is liable to produce a slight i?idigestiou and 

 rise of temperature. This should be avoided as far as possible, 

 and when a herd is taken up from pasture for the test, it should 

 have grass, ensilage or other succulent food. 



12. Cattle just from a long journey b} T road or rail, or other 

 cause of violent exertion are liable to have an elevated tempera- 

 ture from the leucomain poisoning. Such should be left at rest 

 until the transient fever shall have subsided. 



13. Violent handling of nervous cows in taking the tempera- 

 ture must be carefully avoided. The operator who cannot handle 

 them gently is not fit for this work. 



14. There must be evidence that the animals have not been re- 

 peatedly tested at short intervals shortly before. In a number of 

 instances I have found a proportion of the cattle irresponsive to
