LAWES' AND GILBERT'S EXPERIMENTS.

During this period, of twelve days, tlie pigs were all 

 fed on the same food, and were allowed all they chose 

 to eat, and yet it will be seen that the gain is far from 

 uniform. " Those pigs," say the experimenters, " 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 powerful companions had in- 

 dulged to the full, clearly indicated their misfortunes by 

 their weights. After that time, however, very little ir- 

 regularity occurred from this cause vigilant care being 

 taken that each animal should have his full 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 neighbor, in his 

 turn, took precedence at the trough. These ill-tempers, 

 though at first very troublesome, gave way surprisingly 

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

 course of comparative experiments is, after all, much less 

 than in submitting to a faulty allotment." 



The experiment proper, commenced Feb. 14, and con- 

 tinued eight weeks. The following table shows the weight 

 of each pig at the commencement of the experiment :
