Medical Officers of Health Annual Report.
of them had been in attendance at school for over seven
days. The next two cases in that department did not
occur tor three weeks, the first on January 21st, and the
second on January 26th, but they did not attend the
same class at school, although they, on entering and
leaving school, passed through the same corridors. In
this department all the children have a common playground.
In the girls' department the cases occurred in
separate class-rooms. In the boys' department the first

notifications were received, in one of which the symptoms

second on the 27th. On March 5th four notifications
were received, three of these being with respect to two
children and one adult in a previously infected house,

infected had been in close contact in the above day-school
or Sunday-school, and it was also ascertained that of the
earlier cases several were in attendance on the Sundayschool,
which was held partly in the same building as
the day-school. The board school, although attended by
