TBINIDAD AND TOBAGO BULLETIN. [XIX. 4 



■ (3) The tuberculin must be injected with a clean, sterile hypodermic 

 syringe into the subcutaneous tissue. 



(4) The temperature must be taken at the 9th, 12th, 15th and 18th 



hour after injection. 



(5) Animals in which the temperature during the eighteen liours 



following the injection rises gradually from the normal 

 (between 101° and 102'') to 104° or more, may be classed as 

 tuberculous, and those iii which it remains under 103° as 

 non-tuberculous. When the maximum temperature attained 

 is under 104*^ but over 10o° the case must be considered 

 doubtful, and the animal re-tested after a month. 



The result of a test carried out at the Government Farm in May last 

 on sixteen cows and three oxen is given below. One animal " Rhoda " 

 gave a doubtful reaction but on re-testing proved negative. 



It is the intention of the Department to test all the Dairy herd at 

 the Farm in 1922 and the result will be published as soon as possible 

 after the test has been made.
