NOTE EXPLANATORY OF VI "DIFFERENCE TABLES," ( PAGES 577-578 ) ,
AND VII "RESULTS OF EXPERIMENTAL FEEDING," (PAGES 679-582).

Although "difference tables" have been printed in the last eight reports,
accompanied by full explanations of their meaning, they are so condensed from
the data of Table V that explanatory notes seem still in order.

When a cow eats a certain ration during a feeding period, another during
a second period, returning to the first ration for a third period, all three being
of equal lengths, and, so far as may be, all other things being equal, it is fair
to assume, and in the discussion of feeding experiments it is usually assumed,
that the average of the results obtained during the first and third periods on
the ration then fed is what would have been secured during the second period
had the feeding continued on one ration. A comparison of this average with
the results actually obtained with another ration serves to show the relative
value of the different fodders and feeds. The difference between these calcu-
lated averages and the actual results form the "differences" which measure the
relative values of the two rations.

The first comparison of the record of the cow Stella (page 564) is given
in full to show more clearly Just what is meant by the figures in the "dif-
ference tables."
