measure for relief in acdtel laryngeal
affections. veterinary surgeons have
now adopted tracheotomy tubes as per-

sion Of air to the lungs Of 'roarers."
This Is by ro means rare procedure,
and many carriage horses may be daily
seen in London and elsewhere wearing
these tubes md working without ihcon-
venience. Like observation may be oc-
casionally made in the hunting field,
and, IN certain instances, horses, which
without them couldnot have gallopeda
mile without the greatest discomfort to
themselves and danger 10 their riders
have with the aid of tubes been hunted
for five seasons. lr. tle Ar
The operation itself is q very simple
one. It Is usually performed with the
patient standing. o longitudinal ms
cision being made through the skin
covering the trachea, usually from six
TO twelve inches below the thyroid
cartilage. The muscles are then sep
arated, the trachea incised, and, II In
tended as a permanency, an orifice for
insertion OF the tube is made by exeis-
ing a portion Of three rings Bleeding
Is rarely profuse. and ordinarily moves
sells are ligatured and no forcipressure
applied. N'''
The tube best adapted for permanent
use supports itself in position. 1t Is
composed OF three separate pieces, two
OF which, when inserted, form a shield
applied 10 the skin, each having d iiange
in the hmen Of the trachea, the one be-
ing directed upward, and the other
downward. The third piece, the last to
be inserted, Is a hollow cylinderopeh at
each end, which prevents the cut cart
ilages from falling in. The tube Is
usually Of white metal, silver-plated.
For some time after the operation a
muco-purulent discharge may necessi-
tate the daily removal and cleansing Of
the tube. When healing Of the wound
is complete the tube is often allowed to
remain in for weeks without removal
The horse appears 10 suffer no incon-
venience. Pneumonia or accident is Of
very rare occurrence. Excessive gran
ulation sometimes callsfo the interven-
iion Of the veterinary surgeon, but in
the ordinary way the groom removes
and replaces the tube satisfactorily.--
