propagated from heifer to heifer and is
of the Beaugency stock. The virus
originally comes from disease peculiar
to cows known as cow-pox. After TIE
vaccination an apron is placed over The
vaccinated surface as protection against
lirt The effect on the cali is hardly
noticeable. Food is taken as usual, and
mp to the sixth day there is no striking
change in the vaecinated places BY
that time the vesicles are filled. and the
virus is taken from the sixth to the
seventh day Pure vaccine lymph is
colorless; a rcd tint indicates the pres
ence of blood When a quill or point
presents a red or brown tint it is due to
the presence of blood; a yellow tint indi-
c1tes the presence of pas, eash Of which
is foreign and possibly dangerous ma.
terial Nothing but quill slips are used
by this establishment.
The quilts are boiled to rid them Of
any grease, then filed, split and pointed
