The " solids not fat " were again satisfactory and much, 

 above the standard as a rule in both lots. A summary of the 

 results is given in Table XXXVI.

Lot I. in this case not only gave more milk than it did in 

 the previous experiment, and more also than did lot II. in 

 the present experiment, but at the same time increased in 

 live-weight on the average by 62 Ib. per cow. Lot II. increased 

 in average live-weight during the first month, but lost again 

 in the second, so that at the end of the experiment it was on 

 the average exactly where it was in the beginning. Taking 

 the whole period of sixteen weeks, covering both experiments, 

 lot I. gained, on the average, 20 Ib. per cow in that time, and 

 lot II. lost 21 Ib. The two lots gave very nearly the same 

 amount of milk during the sixteen weeks they were under 

 experiment.
