Abstract
THE report on the operations of the Survey of India for the year 1907-8, in addition to the usual record of map-making of a utilitarian character, contains several features of scientific interest. We have long been accustomed to a high standard of work from this department, and it cannot be other than a subject of congratulation that we should see evidence, not only of the maintenance of its previous level, but also of continuous advance. The most recently completed geodetic triangulation, extending for a distance of 480 miles from the Indus to the peak Koh-i-Malik Siah, the junction point of India, Persia, and Afghanistan, is the most accurate operation of its class ever carried out in any country. Computed by the ordinary methods, the probable error of a single angle is 0″.21, a quantity not much more than half that of the corresponding figure obtained in any triangulation outside India.
