Alexander Tulloch made a name for himself in India through his hobby of compiling statistics and extracting useful information from them. He would collect statistics on sickness and mortality data for the troops on foreign stations. He noticed that there was a tendency for military pensioners to live to extreme old age. He was able to show from the statistics he collected that the relatives of deceased soldiers were concealing their deaths so they could continue to draw the pension. He also exposed a number of frauds carried out by the East India Company, on the common soldier by depriving them of their pay and forcing them to buy goods at extortionate prices.
