The result so obtained would in general be more accurate than

the Jewish calculation, from which it may differ a day, as fractions of a day do not enter alike in these computations Such difference may also in part be accounted for by the fact that the assumed duration of the solar year is 6 min 392% sec. in excess of the true astronomical value, which will cause the dates of commencement of future Jewish years, so calculated, to advance forward from the equinox a day in error in 2 16 years. The lunations are estimated with much greater precision. The following table is extracted from Woolhouse's M easures, Wezghts and M oneys of all N ations.-TABLE VII — Hebrew Years.

Thursday the 1 5th of July A.D 622, and it commenced on the day following. The years of the Hegira are purely lunar, and always consist of twelve lunar months, commencing with the approximate new moon, without any intercalation to keep them to the same season with respect to the sun, so that they retrograde through all the seasons in about 32% years. They are also partitioned into cycles of 30 years, IQ of which are common years of 354 days each, and the other II are intercalary years having an additional day appended to the last month. The mean length of the year is therefore 3 54% days, or 3 54 days 8 hours 48 min, which divided by 12 gives 2Q%% days, or 29 days 1 2 hours 44 min, as the time of a mean luna tion, and this differs from the astronomical mean lunation by only 2-8 seconds. This small error will only amount to a day in about 2400 years.

To find if a year is intercalary 0r common, d1vide it by 30; the qu0tient will be the number of completed cy cles and the remainder will be the year of the current cycle; if this last be 0ne 0f the numbers 2, 5, 7, Io, 13, 16, 18, 21, 24, 26, 29, the year is intercalary and c0ns1sts of 355 days, if it bc any other number, the year is 0rd1nary

Or if Y denote the number of the Mahommedan year, and R: (Ill/-l 14
