On April 26tb, 1850, the pigs were allotted by weight to the 

 different pens. They were taken from a -stock of 40, all of about 

 nine months old, which had been bought at different styes and 

 markets, in lots respectively of four, nine, eight, eight, and 

 eleven ; and, as before, they were on the following day changed 

 from pen to pen, so as to disturb as little as possible the weight 

 within each pen, and at the same time to secure greater equality 

 as to the character of the animals between pen and pen. 



Table v., which follows, shows the weights of the pigs in each 

 pen as thus allotted.

After the allotment and this first weighing, all the pens were 

 supplied with a mixture (given ad libitum) of one part Bran, one 

 part Bean and Lentil meal, and one part Barley-meal. Upon 

 this food they were kept for 13 days prior to commencing the 

 exact experiment. There was, as usual, some inconvenience 

 during this preliminary period until the pigs became accustomed 

 to their new situation and new companions ; and this of course 

 accounts for some of the irregularity in increase during this pe- 

 riod, as shown in Table VI., which follows.
