CURIOUS CALCULATIONS.
CONSUMPTION OF AIR IN ACTIVITY AND REPOSE.
Dr. Radclyffe Hall makes the following interesting statement with
regard to the amount of air we consume in repose, and at different
degrees of activity: When still, we use 500 cubic inches of air in a
minute; if we walk at the rate of one mile an hour, we use 800; two
miles, 1,000; three miles an hour, 1,600; four miles an hour, 2,300.
If we run at six miles an hour, we use 3,000 cubic inches; trotting a
horse, 1,750; cantering, 1,500.
THE VALUE OF LABOR.
Cast iron of the value of L1 sterling is worth, converted into
ordinary machinery, L4; in larger ornamented work, L45; in buckles and
similar kinds of fancy work, L600; in neck chains, L1,300. Bar iron of
the value of L1 sterling is worth, in the form of knives, L36; needles,
L70; penknife blades, L950; polished [Transcriber's Note: The original
text reads 'bottons'] buttons and buckles, L890; balance springs of
watches, L5,000.
INTEREST OF MONEY.
Dr. Price, in the second edition of his "Observations on Reversionary

improved for some time at compound interest will increase.
