78 BOVINE TUBERCULOSIS AND OTHER CATTLE DISEASES. 



The services of at least one non-professional assistant, besides 

 the stable-man, will be found very useful. He could be 

 employed to insert thermometers and to record the tempera- 

 tures on the blank provided for the purpose. The responsible 

 work of reading the thermometers can thus becarried on 

 rapidly by the veterinarian making the test. V^FTg. 10 shows a

convenient blank for recording temperatures. It will be noted 

 that the temperatures are written in an abbreviated form. For 

 instance 101.6 is recorded as 1.6, etc. The blank as used is 

 three inches broad and about seven inches long. The width 

 permits folding the records and filing them away with the 

 identification cards mentioned on page 81. The significance of 

 the numbers in the column at the extreme right is described 

 ^n page 82. 



After the temperature is read, the thermometer is inserted in 

 a pot of vaseline until needed for use next time. If there is 

 no convenient ledge at the rear of the cows, a light portable 

 box, about a yard high, forms a convenient stand for the vas- 

 eline and thermometers.
