But to infer at once from this that every thing in the book was derived from Greek or Arabian writers, or that it was inseparably mixed, would be reasoning too hastily. A little patience will discover evidence of the algebra which it contains, being purely Hindoo.

The following paper consists of an account of this translation, and some notes which I shall now mention:

The papers which contain his notes had long since been mislaid and forgotten. They have been but very lately found, and I gladly avail myself of Mr Davis's permission to make use of them here. The chief part of them is inserted at the end of my account of the Persian translation. To prevent misconception about these notes, it is proper for me to observe that in making them Mr. Davis had no other object than to inform himself generally of the nature of the Blja Ganita; they were not intended probably to be seen by any second person; certainly they were never proposed to convey a perfect idea of the work, or to be exhibited before the public in any shape. Many of them are on loose detached pieces of paper, and it is probable that, from the time they were written till they came into my hands, they were never looked at again. But nevertheless it will be seen that they do, without doubt, describe accurately a considerable portion of the most curious parts of the Bija Ganita; and though they may seem to occupy but a secondary place here, they will be found of more importance than all the rest of this work together.
