vious years. The colder months show no marked predominance over the warmer
months as regards the success rate.

11. Table IX shows the maximum and minimum periods during which lano-
linated vaccine was stored before issue for each month this year. As usual the
storage period was longer during the hot months when no vaccine was made.
The averages of the maximum and minimum periods of storage of lanoline paste
during the months April—September in 1915-16 and 1916-17 are 119-69 and
146-49 days, respectively, whilst the corresponding figures for the months of
October—March are 58-5 and 51-28 days, respectively. How far the lower per-
centage of success in the year was due to the larger amount of material issued
being of longer storage is a point worth investigating.
