Abstract
Lynch's Explorations in Mesopotamia AT a meeting of the Geógraphical Society on November 25, thanks to the president of the India Board, a communication was read from Lieutenant Henry Blosse Lynch (1807–73) of the Indian Navy relating to his survey of the River Tigris between Ctesiphon and Mosul. “Chains of triangles,” said Lynch, “covered Nineveh to Baghdád, Baghdád to Babylon, Babylon to Ctesiphon, Ctesiphon to Baghdád, and the mountains of Hamrin in two points, namely, where the Tigris bursts through them in the N., and Wiyálah to the north-eastward; most of the principal points within the range of these are fixed either by an extension of the trigonometric chains, or by latitudes and true bearings checked by longitudes; the great canals also have been touched by our work sufficiently to show their direction and position. As we work, the field, instead of being diminished, appears to extend; and I have been obliged to leave with regret the tracing of the splendid canals and rivers, and the filling in of the villages and ruins, for more favourable times. . . ."
