It may not be uninterefling to examine the rule by which 
the Arabians appear to have been guided, in placing the inter- 
calary day at the end of thofe particular years which have been 
fpecified. It was obferved, that the annual excefs is calculated 
to be 11 parts in 30 of a day. At the commencement of the 
firft year of their firfl cycle, they appear to have aflumed the 
fadt (fomewhat capricioufly) that there was then an excefs of 
11 parts, belonging to the preceding year, to be accounted for, 
or brought on. At the end of the firffc year there w T ould conie- 
quently be 22 fuch parts; and at the end of the fecond year 
^3 parts. Here then the firfl: intercalary day was applied ; that 
fecond year w T as made to confift of 355 days, and there re- 
mained 3 parts, over and above, to be carried on to the next.
