dermically in several places in direction of proposed cutting. 
Antiseptic. —Treatment for hands and instruments use 3 
per cent, solution carbolic acid. 
Sponges. — 1. Beat to rid of all sand. 2. Wash in warm 
water till clean and unclosed. 3. Put into 5 per cent, sal car¬ 
bolic acid which is changed every second day till eighth. 4. 
Then boiled for fifteen minutes in a solution of bicarbonate of 
soda. 5. Keep in a 5 per cent, solution of carbolic acid till 
wanted. 
Everything being ready, proceed by first securing the ani¬ 
mal whether by twitch alone, stocks or side lines, also consid¬ 
ering the position best suited for performing operation. Be¬ 
fore casting or securing, detail your assistants ; the injection of 
local or other anaesthetic is now in order, and when sufficient 
time has elapsed, say five minutes, alwavs if practical cut 
in direction of the natural lie of the hair (if possible), as when 
altogether healed the scar, if any, will be quite undetectable. 
Modus operandi. —This is quite practicable when you have 
simply an abscess. First insert your director into sinus and 
with a strong scapel or probe-pointed bistoury lay open . 
freely ; your grasp of the knife must be firm and rigid and 
your arm steady. Stop all bleeding by properly ligaturing 
and artery forceps when readily applied. Syringe out with gen¬ 
tle force with antiseptic solution, which may be cold, to con- 
stringe vessels. The depth and extent of the cavity can be 
judged and direction of all sinuses ; if cut was of a free nature 
to allow of suffiicent dependence, proceed to dissect out pir- 
genic membrane; this may have been extensive and involve 
much cutting; if so, conserve tendinous or belly part of mus¬ 
cles and cut longitudinally, but get to the bottom of the 
trouble else failure will be yours. 
Escharotics, as nitrate of silver, arsenic, etc., can be applied 
to terminal pipes, especially so where cutting would be dan¬ 
gerous. I have found that the application of a large, soft 
emolient poultice, with free sedative spraying, which is very 
soothing, that the warmth and moisture have increased the 
healthy granulation and the remaining pipes were readily 
detached, especially so when the most dependent parts were
