10. Table VII shows the percentage rate of success in five districts selected
for comparison. Gōdāvari on this occasion is the lowest and its average for the
five years is coming dangerously close to that of Coimbatore. These comparisons
have now been shown for the past eleven years and have been consistent through
out, Coimbatore and Gōdāvari always bad and at the bottom of the list; Bellary,
Anantapur and Kurnool always good and at the top of the list. The distance
between the two groups is also steadily increasing. When the comparisons were
first started, Coimbatore was on an average for the years shown 14 per cent
worse than Bellary. Now on an average of the past five years Coimbatore is
23.21 per cent worse than Bellary and 24.1 per cent worse than Kurnool.
Kurnool is as remarkable for its consistency as for the goodness of its results.
During the last five years the maximum variation in its success rate is 0.31
per cent.

in affecting the quinquennial average which shows a defined seasonal curve.

12. Table IX shows the maximum and minimum periods during which
lanolinated lymph was stored in the cold room during the official year. As
pointed out in paragraph 7 the vaccination of calves had to be carried on more
continuously and therefore the periods of storage were necessarily shorter. If, as
some have held, storage be detrimental to the vaccine, some evidence to this effect
should be got by a comparison of this year's figures with the last. The average
minimum period of storage last year was 38.3 days, this year 13.4 days, barely
more than a third of the time ; the average maximum period of storage last year
