The weighings of the calves were made each morning beforé be- 
ing fed, and hence apply to the effect of the food of the preceding 
day. An inspection of the record shows that it may be studied in 
two divisions, the one represented by under 14 lbs. of sweet milk fed, 
and the other by over this quantity. Averaging, therefore, the 
weighings which represent the feeding periods from July 14 to 19 
and July 20 to 31, we have :—

The progress of these two animals are so nearly parallels that we 
can average the figures gained :—

These figures have this instruction. The excess of milk above a 
certain quantity has a greater value as expressed in gain than the 
preceding quantities, or otherwise expressed, only the quantity fed 
in excess of what is required for maintenance is expressed in increase 
of live weight. If these figures be interpreted exactly, which proc- 
ess of interpretation is allowable for illustration, as 12 lbs. of milk 
fed daily gave .83 lbs. daily increase of live weight, and 17.7 lbs. of 
milk gave 1.96 lbs. daily increase of live weight, then 5.7 lbs. of in- 
crease of milk in ration gave 1.13 lbs. of gain in live weight, or the 
average daily gain of live weight per pound of milk fed in the 12 lb,
