contained a very high percentage of moisture, largely explainable,
doubtless by the nature of the sub-soil, and, in a lesser
degree, by the altitude of the District.
Bacteriological and Chemical Laboratory.
The following is the record of the work done in the
Council's Laboratory during the year:—
Diphtheria.
One hundred and forty-seven swabs were examined. Of
these 147:

102 were negative
9 were sterile.
35 "Immediate" examinations were made, of which two
were found positive and 33 negative. Of the latter 4 of the
cultures proved to be positive. The stain used is Toluidine
