XI. Translation of a passage in Ebn Younes; with some remarks thereon: in a letter from the Rev. George Costard, M.A. Vicar of Twickenham, to the Rev. Samuel Horsley, LL.D. Sec. R.S
Rev. Sir, Having, by means of the Royal Society, been favoured with a transcript of the Arabic passage in manuscript of Ebn Younes, in the library at Leyden, I now send you as exact a translation of it as I can. I give it to you as exact a translation of it as I can. I give it to you in Latin, as the former translations of it were in that language; and as the numbers in the manuscript by no means agree with calculations made by modern table, I have ventured to suppose that they have been somehow or other altered from what they were in the original tables of Ebn Younes. I have likewise ventured to suppose that the present Leyden copy is a transcript of another copy, which is no very violent supposition, considering how long ago these observations have been made, and how long it is since Ebn Younes wrote.
