16 THE HYPODERMIC METHOD OF TREATING DISEASE. 
capable of receiving the chisel; a long handle is attached to 
the bottom of the claw by a swivel joint, which permits the 
necessary adjustment to be readily made. 
Having myself tested the instrument and found it to be 
practically valuable, 1 am induced to offer it to the notice of 
the profession. 
In performing the operation of cutting off a superior molar 
the chisel is first placed in the claw of the director, and then 
fixed on the tooth in the usual manner. An assistant is 
required to hold the director, and by its aid to keep the chisel 
firmly in its proper place, while the operator, holding the 
handle of the chisel in his left hand, strikes with the hammer 
in his right hand a smart blow, which is generally sufficient 
to cut off the projecting tooth level with the rest, leaving 
but little to be done with the rasp afterwards to render the 
operation perfect. 
QUERIES ON THE HYPODERMIC METHOD OF 
TREATING DISEASE. 
By B. H. Russel ( Captain ), M.R.C.Y.S., Grantham. 
I am anxious to ascertain in what diseases of the lower animals 
the hypodermic method of treatment has been employed,'and 
with what success ? Also, what medicinal preparations have 
been used, and in what quantities, and how often they have 
been repeated in the same case ? The maximum dose which 
can be safely repeated is also an important question. 
We so constantly read of the success attending the employ¬ 
ment of the hypodermic method of combating disease by our 
medical confreres , that I am at a loss to know how it is 
veterinary practitioners do not embrace like opportunities of 
giving similar information. 
I hope this letter will have the desired effect of eliciting 
replies to my questions, and of obtaining, through your pages, 
a free discussion on the use of so valuable an instrument as 
the hypodermic syringe. I have been endeavouring for some 
time past to procure a treatise on the subject, but to the 
present have been unsuccessful. In my college days the 
subject of injecting medicinal agents under the skin was not 
entertained; but I doubt not under the present regime both 
it and the use of the clinical thermometer will obtain a proper 
share of attention. 
I have been offered an old pony for experimental purposes, 
and am the more anxious on this account to get the requisite 
information with the view of testing, so far as practicable, 
the action of the different preparations now in use.
