(vii) Hunter¹ tells us that he met at Ujjain a grandson of Jai Singh’s principal assistant (? Jagannāth). “In his possession,” he writes, “I saw the translation into Sanskrit of several European works, executed under the orders of Jaisingha, particularly Euclid’s *Elements*² with a treatise on plane and spherical trigonometry, and on the construction and use of logarithms which was attached to Cum’s and Commandine’s edition. In this translation the inventor is called Don Juan Napier³ . . . . Besides these the Pandit had a table of logarithms of logarithmic sines and tangents to seven places of figures, and a treatise on conic sections.”
