properly, and imagined that aryabhata (Arab, drjahhad)
meant cc thousandth part. The Hindus pronounce the
cl of this word something between a d and an r. So
the consonant became changed to an r, and people wrote
drjabhar. Afterwards it was still more mutilated, the
first r being changed to a s, and so people wrote dzja-
bhar. If the word in this garb wanders back to the
Hindus, they will not recognise it.

Further, Abu-alhasan of Al'ahwaz mentions the revo- star-oycies

therefore, they give us the theory of Aryabhata. Some
of these numbers agree with the star-cycles in a catur¬
yuga, which we have mentioned on the authority of
Brahmagupta; others differ from them, and agree with
the theory of Pulisa; and a third class of numbers differs
from those of both Brahmagupta and Pulisa, as the
examination of the whole table will show.
