consider the Increase obtained, in relation to the constituents of 

 food consumed. 



In Tables VIII. and IX., which follow, we have the weights 

 of the pigs in this Series when allotted to the pens — their gain in 

 weight during the preliminary periods — and their weights at the 

 commencement of the exact experiment.

Showing the Weights of the Pigs (in lbs.) when allotted to the Pens (Pens 1, 2, and 3, 

 Feb. 2, 1850— Pens 4 and 5, April 26, 1850.)

As seen in Table VIIL, the pigs in Pen 3 were not weio-hed 

 when first allotted to the pens ; and hence their gain in weight 

 during the preliminary period cannot be given, but only their 

 actual weight at the commencement of the experiment. The gain 

 in weight in Pens 1, 2, 4, and 5 is seen to be singularly uniform 

 during the preliminary periods ; and the actual weights at the 

 commencement of the experiment, of Pens 1 and 2 respectively, 

 and again of Pens 4 and 5, agree very well together.
