did not produce any evil effects, and notwithstanding the unpleas¬ 
ant effects resulting from this error, the animal recovered from an 
attack of tetanus which the Doctor thought would prove fatal, he 
having advised the use of antitoxin as the only chance for re¬ 
covery. 
With the exception of this mistake, I wish to thank Dr. Lam- 
kin for reporting this case and to mention the New York Pasteur 
Institute as the source of supply of the antitoxin. 
Yours sincerely, PAUL GlBlER, M.D. 
SOME ERRORS IN PROOF-READING. 
)f - ' Mamaroneck, N. Y., Feb. 5, 1896. 
Editor of American Veterinary Review: 
In the February issue of the Review, on page 719, Dr. W. 
F. Derr, in his report of a “ Complicated Case,” says, “ I then 
gave him fl. ex. can. ind., half pint; fl. ex. belladonna, one ounce.” 
Were this all I would take it that the “ half pint ” was an error on 
the part of the printer, but further on he states that “ gave him 
one and a half pints raw oil and added half pint doses fl. ex. 
nux vom., every four hours.” I can easily believe that the 
patient would survive one and a half pints of raw oil, but I am 
still thinking how many half-pint doses of nux vomica would have 
been necessary to prepare him for a post mortem. I do not wish 
to reflect on the REVIEW by my remarks, but I could not let 
that go by without some mention. I do not think Dr. Derr 
meant us to believe that, and therefore attribute it to the uncer¬ 
tainty of printers.’ ink. 
Yours most sincerely, C. Henry Doepel, D.V.S. 
[The correspondent has correctly guessed the cause of the error complained of— 
it was the careless proof-reading of the medical reviser. The doses were indicated 
by the usual symbols, and were mistaken in the composing room. If any further 
explanation is necessary we will state that Dr. Derr wrote the dose of the fluid ex¬ 
tract of cannabis indica as half an ounce ; fluid extract of belladonna, two drachms ; 
and of nux vomica, half a drachm.—E d.]
