In Class I. (percentage unprotected 9) no case occurred.
In Class II. (percentage unprotected 14) one case occurred during Christmas holidays.
In Class III. (percentage unprotected 26) one case occurred during the Christmas holidays.
While five cases occurred on June 16th to June 19th, which were part of a general prevalence
of measles, no cause could be found in school; the class was closed from June 22nd to July 6th>
and during this period one case occurred. There were only thirteen cases in this class who had not
previously had measles, and of these five contracted it during the year, while of the forty-two who
were reported to have had measles two were said to have a second attack (diagram XV).
In Class IV. (percentage unprotected 28) one case just before the Christmas holidays had
measles, and three cases occurred during the holidays; no further cases occurred during the year ;
the four were amongst those reported not to have had measles.
In Class Va. (percentage unprotected 43) one case occurred during the general prevalence in the
Christmas holidays; two further cases occurred on June 16th to 18th, and the class being closed
from June 19th to July 4th, eight cases came down during the closing period of fourteen days.
Unfortunately the case that had occurred on the 18th of June was not known about till afterwards,
so that the closure was just too short, and two children came back on the 4th July who had
contracted it from the second case. This necessitated closure, recommencing on July 5th and
oarried on into the summer holidays; and it was impossible to ascertain the occurrence of further
cases on this account. Of the 13 cases known about 10 were among the 26 reported not to have
had measles before.
In Class Vb. (percentage unprotected 41) a case occurred on June 3rd, and the class was closed
from the 10th to the 19th ; no secondary case was discovered to have occurred during the closing
period, but between the 20th June and 10th July 9 fresh cases occurred (this beiDg
part of the general prevalence). The class was again closed on July 10th, and the closing merged
into the summer holidays, so that here also the channel of information was cut off, and the
subsequent history is unknown.
The case which occurred on June 3rd, and primarily introduced measles, had only been at
school three days, and must have contracted it outside. The 10 cases of measles that were known
to have occurred were all among the 16 children reported not to have had measles previously.
In Class VI. (the Babies) 52 per cent. were unprotected. One case occurred in the
Christmas holidays ; four cases occurred from March 1st to 3rd who contracted it from outside
source—indeed, one of these four cases had not been near the school for months and was
not in attendance. The class was closed from March 4th to 21st, but no further case was
discovered during this period. Another case occurred on April 12th, during the Easter holiday,
which was secondary to a baby in the house. Another case failed on June 8th, and the class
was closed from June 9th to 23rd. No secondary cases occurred, however, during this period, but on
