Renewal of Lymph from Heifers.

tion be continued, and its practice extended to other cities, India will be in possession
of as good vaccine lymph as can be obtained from England itself.

15.     On two occasions I inoculated heifers in my Circle, and thereby renewed
the lymph in several talookas. I experienced no
difficulty whatsoever in procuring heifers, and, far
from meeting with any opposition, great anxiety was shown by all to be vaccinated
from that pure supply.

16.     I propose making during the year a series of experiments with dried lymph
on ivory points, and liquid lymph in tubes, or preserved between plates of glass.
If, as I believe, points are found to give a higher percentage of success, they should
on this score alone be preferred. Points being so much easier to charge than
tubes to fill, the Vaccinator could always carry with him a large supply of lymph,
and, once taught how to use them, would obtain very fair results. At present
the Vaccinators have frequently to put up with bad lymph, as it is not the child
presenting the best vesicles that can always be conveyed to another village, but
the one whose parents are willing to go. One point can only be used for one super-
ficial incision, and the bad practice of vaccinating a large number of children from an
inadequate supply of lymph would then be obviated.

Animal Vaccine a good and pure
source of Lymp.

17. I believe that we have now the means of keeping up a good supply of vaccine
lymph ; but unless the same advantage is extended
to the Vaccinators themselves, all our efforts will be
made in vain. I supplied on one occasion some very
good lymph to the Sub-Assistant Surgeon in charge of one of the Callian Dispensaries,
and with it he vaccinated three children ; in two (I saw them on the eleventh day) he
obtained beautiful vesicles ; in the third, vesicles were very indifferent, almost spurious.
To my astonishment he had taken lymph from these bad vesicles for vaccinating other
children ; the result was unsuccessful, and he lost his supply. If Sub-Assistant Sur-
geons, who are supposed to know better, cannot distinguish between good and bad
vesicles, what are we to expect from the generality of our Vaccinators.

Supernumerary Vaccinators de-
sirable.

18. Two or three supernumeraries should always be attached to the Superin-
tendent's Office, and thoroughly trained in every
detail of their work, before they are employed as Vac-
cinators. The want of properly trained men, always
at the disposal of the Superintendent, is a want I have greatly felt. Having had to
make lately several appointments under the Local Funds, I had no alternative but
to appoint men whom I could get, and who were in some respects not well suited
for the work. I kept them all for some time near me, allowing them to draw part of
their pay ; but they had studied under our Vaccinators, and it is well known how
much more difficult it is to "unteach" than to "teach." These supernumeraries (who
should receive pay at the rate of from ten rupees to fourteen per mensem), after a
few mouths' training, would be of the greatest use. They would be always at hand,
