96 FINE WOOL SHEEP HUSBANDRY. 
fer the sheep which produces it in greatest abundance. 
But in the production of ptre wool, my own opinion 
is that the heaviest fleeced animals of the two varie- 
ties do not materially differ—not more perhaps than 
is inevitable, other things being equal—by reason of 
that law of matter which gives small spherical bodies 
more surface in proportion to weight and diameter 
than larger ones. The carcass of a sheep has sufficient 
sphericity to make this law applicable to it. A better 
idea of its practical effects will be obtained from an 
examination of the following table, prepared in rela- 
tion to round shot:

It will be observed that while the disparity in pro- 
portionable surface between the extremes given, is 
enormous, that it diminishes as between larger spheres. 
But notwithstanding this, all must see that between 
spheroidal bodies differing fifty per centum in size 
and weight (equivalent to the difference between the 
French and American Merino), the greater propor- 
tionable surface of the smaller body must be sufficient 
to make*s material difference in its favor if that sur- 
face is to be covered with wool of equal thickness 
and length. To express the result more practically, 
the American Merino has more square inches of sur- 
face, in proportion to its size, for wool to grow on, 
than has the larger French Merino. And the general
