W.W. McNAIR.--We are sorry to have to record the death of this distinguished member of the Indian Survey, who has died at Mussooree of typhoid fever. He had been twenty-two years in the Survey Department, and had done good service, particularly during the Afghan war of 1878-79, when his work lay along the valley of the Kabul river, and during the last two years, in which he has been extending a series of triangles from the British frontier at Dera, Ghazi Khan, by the direct route across the Suliman Mountains to Quetta and the Khojak Amran.
