vious years, with certain extensions necessitated by virtue of the
passing of the Milk (Special Designations) Order, 1936. A summary
of the work carried out during 1937 appears below, and from
the figures there set out, it will be seen that the position is relatively
satisfactory. When, however, it is realised that two samples of
raw milk prior to pasteurisation revealed the presence of the
bacillus tuberculosis, it will be seen, first, that the investigations
are very well worth while, and second, that pasteurisation of milk
supplies is at present, a very definite necessity.
