The
greatest number of deliveries take place in the winter months, and in
February, and the smallest in July, i.e., to February, as 4 to 5 in

Human Strength.--In Schulze's experiments on human strength, he found
that men of five feet, weighing 126 lbs., could lift vertically 156
lbs. 8 inches; 217 lbs. 1.2 inches. Others, 6.1 feet, weighing 183
lbs., 156 lbs. 13 inches, and 217 lbs. 6 inches; others 6 feet 3
inches, weighing 158 lbs., 156 lbs. 16 inches, and 217 lbs. 9 inches.
By a great variety of experiments he determined the mean human
strength at 30 lbs., with a velocity of 2.5 feet per second; or it is
equal to the raising half a hogshead 10 feet in a minute.
RULES FOR SPELLING.
Words ending in _e_ drop that letter before the termination _able_,
as in move, movable; unless ending in _ce_ or _ge_, when it is
retained, as in change, changeable, etc.
Words of one syllable, ending in a consonant, with a single vowel
before it, double the consonants in derivatives; as, ship, shipping,
etc. But if ending in a consonant with a double vowel before it, they
do not double the consonant in derivatives; as, troop, trooper, etc.
Words of more than one syllable, ending in a consonant preceded by a
single vowel, and accented on the last syllable, double that consonant
in derivatives; as, commit, committed; but except chagrin, chagrined.
All words of one syllable ending in _l_, with a single vowel before
it, have _ll_ at the close; as mill, sell.
