REPORT OF THE NATIONAL VACCINE BOARD FOR.
THE YEAR If6o.—The board of the National Vaccine Tata-
blishment report that during the past year 219,490 charges
of lymph have been supplied, being an excess of 14,024
over the number furnished during the preceding year. The
letters of application for lymph received and answered by
the board during the year amount to 12,7113. Thir-
teen thousand eight hundred and forty-nine vaccina-
tions have been perforned by the vaccinators in
Lotion and the rymalv7, connected with the
establishment, besides 106,471 reported vaccinate.' by cor-
respondents. Although small-pox has not prevailed during
the last year to the same extent as in the preceding, it has

persons reputed to have been vaccinated, yet a close inquiry
has ascertained that of theseby far the larger proportion
consists of two classes, three who have been in the time in-
' stance imperfectly vaccinated, sad those who may have
been efficiently vaccinated in infancy or ehiklho.d. but have
contracted small-pox at an adult age. These considerations,
though they should have no tendency to encourage ilietrust
in the efficacy of vaccination, prove the necessity of increased
caution, both as to the manner of performing the ope-
ration, and the quality of the lymph employed.
As regards the performance of re.vaocinatioe, the board
have been able to obtain no evidence whatever that its fre-
quent repetition is necessary, or even desirahle, though
many facts tend to render it not improbrible that vaccina-
tion performed in infancy may lose its protective power
after adolescence. On thew grounds, re•vaccina; ion at an
early adult age would appear decirable.
