the animal. Although this part of the body is best to operate on, it is not 
essential that the inoculation should take place there. It may be accomplished 
by transfusion of blood into almost any part of the body. For instance, 
if there were difficulty in getting at the shoulder, the blood might be injected 
into a more accessible part, as the flank or rump. An animal ought not to be 
inoculated in the tail, the reasons being—in the first place, the tail is exceedingly 
sensitive, and the needle is more apt. to get broken in it than in any other 
portion of the body; and in the second place, it is almost impossible to 
introduce the required amount of blood. : 
The blood having been transferred from the syringe to the beast, the 
operation is complete. It is not necessary to take the temperatures of the 
animals afterwards, as, if proper blood is used, the inoculation never fails. 
When using the trocar and syringe, care must be taken to have them 
properly clean. They should be well washed in warm water which has been 
previously boiled, then rinsed in water containing a little carbolic acid. The 
washers of the piston should be carefully cleansed after use, and rubbed with 
vaseline to prevent the leather or rubber becoming hard and deteriorating. 
The needle also should be carefully washed and dried, and anointed inside and 
out with a little vaseline. 
Nore.—In inoculating large herds of wild cattle, the following addition to 
the syringe has been found to be most desirable :—A three-way tap is brought 
into use, the first aperture of which connects with the nozzle of the syringe ; 
to the second is attached about 10 inches of India-rubber tubing, the opposite 
end of which is kept constantly at the bottom of the (sodawater) bottle of 
blood, which is fastened to the beit of the operator in charge of the syringe ; 
and to the third aperture of the three-way tap is attached a piece of thick- 
walled rubber tubing about 8 or 10 feet in length, and to the other end of this 
tubing is fixed the inoculating needle. (See Figs. 1 and 2.) : 
The use of the three-way tap and long tubing absolutely prevents the 
blood from becoming contaminated. 
It is necessary before operating to expel the air from the tubing. 
If the three-way tap is not procurable, it is advisable to connect the needle 
to the syringe direct with 10 feet of tubing. 
_. The trocar and syringe can be obtained from Carl Zoellar and Company, Courier Buildings, 
Brisbane; or L, Bruck, Castlereagh street, Sydney.
