LAWES' AND GILBERT'S EXPERIMENTS. 



133 



Messrs. Lawes and Gilbert also made a third series of 

 experiments, the pigs being fed on dried codfish, in con- 

 junction with bran, Indian meal, bean and lentil meal, and 

 barley-meal, in different proportions. The codfish was 

 boiled in water, and the meal mixed with it before being 

 fed to the pigs. 



The following table shows the composition of this dried 

 codfish, together with the composition of the other foods 

 used in this and the preceding experiments :

FOOD USED IN MESSRS. LAWES' AND GILBERT'S 



EXPERIMENTS ON PIGS. 



PER CENTAGE RESULTS. 



In pen 1 the pigs were given, and compelled to eat, 14 

 Ibs. each of codfish, per week, mixed with equal parts 

 bran and Indian meal. Of this mixture they had all they 

 could eat, and consumed 47 Ibs. each, per week, and 

 gained 10.09 Ibs. each. 



In pen 2, each pig had, as above, 14 Ibs. codfish, and 

 ate with it 45 1 1 4 Ibs. Indian meal alone, per week, and 

 gained 12.15 Ibs. 



In pen 3 the pigs had a mixture of equal parts Indian 

 meal and bran, and as much codfish as they chose to eat. 

 They ate 47 Ibs. of the mixture of bran and meal, and
