Time.

115. Of all the magnitudes we have to consider, time is the most easily measured. Different nations select different standards of weight, length, surface, volume, and value; but nature has provided all men alike with three natural units for the measurement of time.

(a) The period of the earth's rotation about its axis, (b) The period of the moon's revolution round the earth, and

(c) The period of the earth's revolution round the sun, termed respectively,

(a) The Day, (b) the Lunar Month, and (c) the Year. These are invariable units, as far as we know.

In all the countries of the world the day is the principal unit of time, and this common standard makes it an easy matter to compare foreign methods of computing time with our own. The chief difficulty encountered in forming a table of the units of time arises from the fact that the three natural units are incommensurable-no number of times one being an exact number of times another. We can neither express a year nor a lunar month exactly by days and parts of a day. The solar year is nearly 365

days 5 hours 48 minutes 49 seconds; and the time between the two new moons nearly 29 days.†

116. Previous to 1752 the civil year in England was that introduced by Julius Cæsar. The years that were divisible by 4 were made to consist of 366 days-other years of 365 days only; so that the average length of the civil year was 365 days 6 hours. This differed from the actual duration of the year by an excess of 11 minutes. These excesses had throughout the lapse of eighteen centuries accumulated to eleven days. In the above-named year the method was adopted in England, which Pope Gregory XIII., with a view to correct the defects of the Julian year, had established on the continent in the sixteenth century. According to this plan the leap year is omitted every hundredth year, except the four hundredth. The years 1700, 1800, 1900, &c., not being multiples of 400, have 365 days; but 2000, 2400, 2800, &c., being multiples of 400, have 366 days. It is calculated that this arrangement reduces the error to less than one day in 6000 years. The rule for finding leap year, therefore, is as follows:-if the year be divisible by 4, it is leap year, except when it is an exact number of hundreds, and then only when the number of hundreds is divisible by 4.

117. The year is divided into 12 months, called calendar months; the number of days in a calendar month varies with the month. The following doggerel will make them easily remembered :

Thirty days are in September.

April, June, and dull November:
All the rest have one and thirty
Save the month of February;
Twenty-eight are all its store,
But in Leap Year one day more.

Write out all the leap years from 1867 to 2010.

More nearly 365-2422414 days.

More nearly 29.5305887.
