In the relative amounts of spleen there are only two variations from 
a general average — the Tamworths, with 0.23 per cent, and the Berk- 
shires, with 0.13 per cent. 
In weight of kidneys the Poland Chinas lead, with 0.31 per cent, 
the Berkshires being lowest, with 0.23 per cent. 
There does not appear to be any particularly constant influence due 
to breed or type in the relative weights of those vital organs that con- 
si itute the pluck. The combined weights of liver, heart, and lungs 
should approximate that under the head of pluck; if, therefore, there 
is any influence of breed on the development and Aveights of these 
organs we should expect to find evidences of it in uniform and con- 
stant differences in weights. In the weight of plucks the Berkshires 
lead in the average, with 3.03 per cent, the Tamworth, Yorkshire, 
Poland China, Chester White, and Duroc Jersey following in the order 
named, the lowest weight being 2.86 per cent of the live weight. Yet, 
in relative weights of the organs that are included in the pluck, the 
Berkshires are but once in the lead — in the weight of the heart, where 
less variation is seen than in the weights of livers and lungs, the
