The average composition of all the samples of milk analysed, for each
month of the year, is shown in table G.

These results are satisfactory. The percentage amounts of fat have usually
shown a maximum in November, falling away gradually to a minimum in
June.
This change is shown again in this year's figures relating to percentages
of fat and also total solids. An exception is found in the month of April,
where the fat figure is unusually high.
The proportion of solids-not-fat shows little variation, the April figure
here is rather low.
The average quality of the milk compares satisfactorily with that of
previous years, the percentage composition for the whole year showing a
comfortable margin over the Legal Minimum given above,
