I entrusted to my assistant, Mr. H. Beardmore. On the 21st February each 
of the bulls and 10.healthy young steers received an injection under the skin 
behind the shoulder of 8 c.c. of blood from the No. 2 steer, which was at the 
time suffering from acute tick fever. After inoculation they were all placed 
in a good grass paddock, and well supplied with fresh water. 
Although I had never before attempted to take the temperatures of 
mature bulls after inoculation, it was considered advisable on the present 
occasion that some close observations should be recorded; consequently I 
instructed my assistant, Mr. H. Beck, to commence taking the temperatures of 
10 of the bulls and the 10 control steers as soon after inoculation as possible. 
Owing to the prevailing heavy wet weather at the time, Mr. Beck was unable 
to reach Rathdowney before the 28rd (two days after the animals were 
inoculated); but no time was lost—the animals were mustered, and their 
temperatures taken that morning. Just after having taken the temperature of 
the first bull in the afternoon of the same day, an unfortunate accident 
occurred whereby both of the thermometers got broken, which meant several 
days’ delay in the observations; however, by the 27th February (six days 
after inoculation) Mr. Beck was supplied with a fresh consignment of 
thermometers, and the work of taking the animals’ temperatures was proceeded 
with, and carried on without interruption until the 8th March, or fifteen days 
after inoculation, when all the temperatures had fallen to about normal. 
Now, as to the result of this experiment, not one of the bulls exhibited 
eyen the slightest signs of sickness, neither was there any indication of fever 
in the 10 bulls that had their temperatures taken; beyond the usual elevation 
in temperature for a few hours in one or two individual animals, caused solely 
by excitement, the temperatures remained at normal throughout. But we 
have a totally different condition of affairs with regard to the 10 control steers, 
7 of which were suffering from fever on the sixth day, and by the tenth day 
after inoculation every animal was suffering from a severe attack of acute 
fever— some with most pronounced symptoms of hemaglobinuria (redwater)— 
and the temperature in several instances reaching to nearly 108 degrees Fahr. 
From this date the fever gradually subsided, and by the 8th March all the 
temperatures were duwn to normal. 
The success of these experiments is, in my opinion, privcipally due to the 
following important factors, viz.:— 
1. All the bulls and steers were young, being under three years old; in 
fact, most of them were under two years old—i.e., they were not of a very 
susceptible age. 
2. Although the bulls were bred in New South Wales, they were allowed 
to settle down and get thoroughly accustomed to their new home at Rathdowney 
before inoculation. 
3. Special care was exercised during the inoculation, the animals being 
handled carefully, and each received exactly the same amount of blood. 
4, There were no possible chances of the blood becoming contaminated 
before injection. 
5. After inoculation the animals were well cared for, being placed in good 
paddocks with plenty of fresh grass, water, and shady trees. 
6. The 20. animals—bulls and steers—whose temperatures were taken 
regularly night and morning, were in charge of a thoroughly trained and 
reliable assistant, whose duty towards sick experimental animals is that of a 
hospital nurse towards her patients. '
