When one considers the definite response given by the contact
children to the test doses referred to, one must admit that only
Providence prevents disaster in the case of many who day by day
receive large doses of live germs in infected homes. It is in these
cases that boarding out of contacts is successful in preventing
manifest disease.
Of the 80 children who showed negative reactions, in only 12
could contact with tuberculous cases be admitted, and this was of
indefinite character. In 20 only were the full series of tests made
as it is assumed that a negative reaction to a test dose of 1/1,000 O.T.
excludes infection in children under S years.
Out of some 300 intradermal injections made, in only one case
could the reaction be regarded as excessive. This occurred in a child
aged 4 who in addition to the local reaction developed slight swelling
of the arm tested, and was " feverish " for a few days. Only general
conclusions can be drawn from a small series of tests as that carried
out. The usefulness of the reaction in discovering infected children
is confirmed. It is apparent also that a great number of children
are now growing up without being infected by tuberculosis until
adolescence at any rate.
Ultra Violet Light Treatment.—74 cases were referred for
courses of Ultra Violet Light Treatment during the year. The
number in 1933 was 75. The types of cases included debilitated and
" pre-tuberculous " children, with chronic bronchitis, enlarged glands
of neck, etc. The majority of cases given the treatment showed
marked improvement. In only one or two cases could it be said that
no benefit was received. All cases are examined at the beginning
and completion of courses and treatment is supervised twice a week
bv the Medical Officer.

Care Committee.—During 1934 the formation of a Care
Committee for tuberculosis was considered on several occasions
following representations from the London County Council. As,
however, the system of " assessments " was discontinued it was not
thought necessary to proceed further with the matter.
