Now, suppose you are going to test your herd. Put all the animals into 
bails or into a crush. Take their temperature at 2 p.m., and again at 6 p.m. on 
the day of injection. Inject the tuberculin at 6 p.m, passing all cattle whose 
temperature at 2 p.m. was above 104 degrees. 
After injection, take the temperature every three hours, from 6 a.m. to 
6 p.m. on the following day, until you tind no further rise in temperature, and 
the normal (original, natural) temperature has been resumed. 
The method of using the thermometer can be shown you by any dairy 
farmer or student of the Agricultural College. 
You must now learn How To INJECr THE TUBERCULIN. Fill the syringe 
with the proper dose, and stand on the side of the beast opposite to that on 
which you intend to operate. Reach over the animal with your left hand, and 
punch up the skin firmly at the chosen point with the left forefinger and thumb. 
ith the syringe resting in the right palm, the needle between the forefinger 
and thumb, pierce the skin with a quick thrust, and, while retaining your hold 
of the folded skin, put your right thumb on the piston, and slowly introduce the 
contents into the sub-cutaneous tissue. There you have the word sub-cutaneous 
which I explained to you. 
Now, if, on the following day, the animal’s temperature rises 23 degrees 
Fahr. or more, you may consider that it has tuberculosis. 
Tf any rise is less than this, wait two or three weeks, and repeat the injection. 
As a rule, with tubercular animals, the temperature will begin rising 
TWELVE HOURS AFTER injection, that is, at 6 a.m., and by noon it may reach 
107 degrees Fahr. In a healthy animal the temperature is 102'4 at 9 a.m. 
before injection, falling to 100°8 at 12 noon, and rising again to 101°6 at 6 p.m. 
There is little change after injection in healthy animals. In a diseased beast, 
whilst the temperature before injection is much the same as in the first case, 
yet after injection it will rise to 1031 at 6 a.m., to 106°9 at 12 noon, falling to 
106°1 at 3 p.m., and to 1048 at 6 p.m. 
This change of temperature is called the Re-acrioy. Now, there you 
haye the whole thing in a nutshell. 
Finally: Kill all animals showing outward signs of disease, and destroy all 
carcasses by fire. 
Test all the remainder of the herd every six months with tuberculin. 
Carefully slaughter and examine all animals of little value, such as old 
cows or bulls and very young calves that have shown evident re-action to the 
test. Boil the whole carcasses down for the pigs. 
Separate the re-acting animals from the healthy ones by removing them to 
a distant paddock. Clean and disinfect all the sheds and stalls. All calves 
born of re-acting mothers should be at once removed before they have a chance 
to suckle their mothers. They can be fed with the milk of healthy mothers. 
Carry out the tests by the help of, or at least in the presence of, an experi- 
enced Government official or of a duly qualified veterinary surgeon. ‘These 
remarks on the tuberculin test are taken from the instructions given by Mr. C. 
J. Pound, F.R.M.S., Director of the Queensland Bateriological Institute. By 
the way, I should tell you that the pulse of a cow is felt in front of the shoulder 
joint.
