racter, and all supposed to be about 9 or 10 months old. They 

 were bought in three separate lots, of 6, 20, and 14 respectively, 

 between January 22nd and February 2nd, 1850. On the latter 

 day they were all weighed, marked, and allotted, 3 to each of the 

 12 pens, in such manner as to get as nearly as possible the same 

 weight in each pen. As will be supposed, this distribution by 

 weights alone, did not secure animals of sufficiently equal feeding 

 quality in the several pens. On the following day, therefore, they 

 were changed from pen to pen, so as to provide as much as pos- 

 sible a similarity in this respect between pen and pen, and at the 

 same time to retain a near equality in weight also. This being 

 done, the weights stood as follows : —

The allotment thus completed, the whole were supplied with 

 as much as they chose to eat, of a mixture of one part bean-meal, 

 one part lentil-meal, two parts Indian-corn meal, and four parts 

 bran, these being the articles fixed upon for the subsequent expe- 

 riment. Upon this mixture all were kept for 12 days, prior to 

 commencing with the exact experiment, in order that they might 

 become accustomed to their new situation, and reconciled to their 

 new companions : for, in the allotment the various purchases had 

 necessarily been intermixed, in some cases greatly to the disap- 

 probation and discomfort of the individuals of those purchases. 

 For a time constant quarrels ensued, and the molested animals 

 frequently jumped from pen to pen, until they fell in with their 

 former associates. Indeed, at first, it was no uncommon occur- 

 rence, after they had been left for some time, to find some pens 

 almost deserted and others crowded. The use of ^the whip was 

 found to be very efficacious in settling these disputes, and at 

 length, all seeming to live amicably together, the exact experi- 

 ment was commenced on February 14th, twelve days after the 

 first allotment.
