Agricultural Chemistry. — Pig Feeding. 465 



As would be expected, the increase during this preliminary 

 period was far from uniform — those pigs having flourished most 

 which had fallen in for the lion's share, whilst the weaker ones, 

 which had been obliged to sulk in the rear until their more pow- 

 erful companion had indulged to the full, clearly indicated their 

 misfortunes by their weights. After that time, however, very 

 little irregularity occurred from this cause, vigilant care being 

 taken that each animal should have his share of food ; and it soon 

 happened, that the mere approach of the whip was sufficient to 

 awe the pugnacious delinquent into humble retreat, while his 

 weaker neighbour, in his turn, took precedence at the trough. 

 These ill-tempers, though at first very troublesome, give way 

 surprisingly by a little perseverance ; and the evil of them, in a 

 course of comparative experiments, is, after all, much less than 

 in submitting to a faulty allotment. 



The results of the second weighings, when the exact experi- 

 ment was commenced, namely, on February 14:th, are given 

 below ; —

A glance at this table, by the side of the former one, will show 

 that the gross weight in each pen was not nearly so uniform at 

 the second weighing as at the first. This irregularity is indeed
