should be tested again in two or three months ; in the mean 

 time this animal should be quarantined. When the tempera- 

 tures on the second day are not sufficiently high to indicate a 

 good reaction, yet higher than on the first day, the animal 

 may be regarded as a suspect, and should be quaractined and 

 retested in three or more months; this is especially tiue if 

 there are tuberculous animals in the heid. If the tempera- 

 tures run above 102 degrees F. for several readings on the 

 first day it may be difticult to obtain a distinct reaction. 

 When the temperature remains at or above 108 degrees F. for 

 several readings on the first day that animal should be 

 removed and tested at some later period when its temperature 

 is more nearly normal. As a rule it is not best to test a cow 

 in heat, or a cow near the end of pregnancy, or a cow that 

 has recently calved, or any animal that has just been driven a 

 long distance, or any animal that has just been taken from a 

 car or a boat. 



Always use good thermometers ; the six-inch Hicks ther- 

 mometer is one of the best. Keep the thermometer at least five 

 minutes in the rectum when taking the temperature. Fresh 

 tuberculin should always be employed. This department 

 makes tuberculin and supplies the city of Montgomery, and 

 several veterinarians in Alabama, with tuberculin upon condi- 

 tion that all reports of the tests are to be forwarded to this 

 department. 



The following examples from actual records made in Ala- 

 bama with tuberculin furnished by this department will 

 illustrate cases of reactions, suspicious cases and cases with- 

 out reactions :
