treatment for corneal ulcers by nitrate of silver solution or 
liquid carbolic acid. 
Permit me to suggest what I have found a better plan. 
Produce local anaesthesia by cocaine. Take a stick of ni¬ 
trate of silver (or still better a cone of silver nitrate with 5% 
silver chloride) and pencil the ulcer till white. If the cone is 
used, carefully push the tip through the thinned corneal wall 
at the deepest part of the ulcer. If the wall appears too thick 
or the ordinary stick silver nitrate has been used, puncture the 
anterior chamber through the ulcer with a small bistoury. A 
gush of aqueous humor will follow, and with the decreased 
intra-ocular tension the inflammatory symptoms promptly sub¬ 
side. Antiseptics (solution of silver nitrate, pyoktanin, etc.) 
may later follow as may be indicated. Very truly, 
W. L. Williams. 
ACTINOMYCOSIS IN EXPORTED CANADIAN CATTLE. 
Dominion of Canada, Department of Agriculture, 
Office of the Chief Inspector of Stock. 
Montreal, December 20th, 1899. 
Editors American Veterinary Review : 
Dear Sirs :—My attention has been called to a mis-state¬ 
ment which appears in the report of the paper read by Dr. J. B. 
Wright on the subject of “Actinomycosis,” at the Missouri 
Valley Veterinary Medical Association, in the December num¬ 
ber of your admirable journal, at page 670. Dr. Wright is re¬ 
ported as having stated that “ three per cent, of the cattle shipped 
from Canada to England show the lesions” (of actinomycosis). 
By referring to my annual reports, which are published in 
the Blue Book of the Department of Agriculture, it will be seen 
that from November 1, 1897, to November 1, 1898, out of 117,- 
428 exported from the maritime ports, the inspectors rejected 
114 head. During the same period, 1898-99, they rejected 71 
out of 111,948, and during the same period of 1898-99 they re¬ 
jected 94 cattle out of 97,014 head exported. 
As a matter of fact, any animals showing even slight lesions 
of actinomycosis are not allowed to be shipped from Canadian 
ports. 
The insertion of this for the purpose of stating the facts will 
be appreciated by, Yours truly, 
Duncan McEachran, 
Chief Inspector for Canada.
