The weight of a given measure of corn will also with considerable 
certainty discover the quantity of husk or bran contained in it, compared to 
the quantity of flour; as that grain, which is cut too early, or which is 
otherwise not quite ripe, as happens in wet seasons, shrinks in the barn or 
granary, and becomes wrinkled, and has thus a greater proportion of skin or 
bran than that whjich has been more perfectly ripened, and will hence weigh 
lighter in proportion. 
A test of this kind may enable us to determine whether peas and beans, 
or oats , are preferable, in respect to economy, as provender for horses. A 
strike or bushel of oats weighs perhaps forty pounds, and a strike or bushel 
of peas and beans perhaps sixty pounds; and as the skin of peas and beans 
Is much less in quantity than that of oats , I suppose there may be at least 
fifteen pounds of flour more in a strike of peas and beans than in a strike of 
oats. There is also reason to believe, that the flour of beans is more nutritive 
than that of oats , as appears in the fattening of hogs; whence, according to 
the respective prices of these two articles, I suspect that peas and beans 
generally supply a cheaper provender for horses than oats, as well as for 
other domestic animals. 
But as the flour of peas and beans is more oily, I believe, than that of 
oats , it may in general be somewhat more difficult of digestion; hence when 
a horse has taken a stomach full of peas and beans alone, he may be less 
active for an hour or two, as his strength will be more employed In the 
digestion of them, than when he has taken a stomach full of oats. According 
to the experiment of a German physician, who gave to two dogs, which had 
been kept a day fasting, a large quantity of flesh food, and then taking one 
of them into the fields hunted him with great activity for three or four hours, 
and left the other by the fire. An emetic was then given to each of them, 
and the food of the sleeping dog was found perfectly digested, whilst that 
of the hunted one had undergone but little alteration. 
Another way of distinguishing light corn from heavy is by winnowing; 
as the surface of the light grains being greater in proportion to their solid 
contents, they will be carried further by the current of air which is produced 
by the van; though the heavy grains would roll further on the floor after 
rolling down a grate to separate the dust; because their vis ineitim would 
carry them further after they are put in motion; and their surfaces would 
be resisted by the air no more than those of the lighter grains. 
Finally, there is reason to believe that a progressive improvement of
