EXECUTIVE DEPARTMENT,

Annapolis, February 5th, 1878.

Gentlemen of the Senate of Maryland;

I herewith submit to you the Annual Report of the State
Vaccine Agent.

JOHN LEE CARROLL.

BALTIMORE, MD.,

January 1st, 1878.
To the Hon. John Lee Carroll,

Governor of Maryland;

MAY IT PLEASE YOUR EXCELLENCY: —

As Vaccine Agent I have the honor to respectfully report,
that during the past year I have been able to fully supply all
demands for vaccine virus, made by Physicians of the State.
In all cases perfectly pure lymph, propagated by myself upon
the heifer, has been furnished. The process of inoculating
heifers, in an unbroken series, one from another, has been
rigidly kept up; and thus lymph perfectly free from any con-
tamination has been the only kind kept or issued. Thus en-
abling the physician to positively assure his patient against
any taint.

It is a well ascertained fact, that while the possibility of
communicating constitutional syphilas by vaccination with
humanized lymph, is beyond cavil or. doubt, it is perfectly
iinposible to contaminate any one with virus from the calf,
since into these young animals, no human ingenuity has yet
been able to plant the germs of that slimy poison which so
subtly works its way through the flesh and bones of man.

During the past year I have inoculated twenty-four calves,
which were selected with great care. An idea, which
existed in the minds of many farmers, that their calves
would be injured for stock or breeding purposes, by the in-
oculation with vaccinia, has given considerable trouble,
but by repeated guarantees, and by occular demonstration
that their fears were groundless, I have succeeded in partially
removing this prejudice. Still a great many are averse to per-
