Thursday August 2, 1894
Mr A.G. Fowler came with reference to boundary commission between French & English territory in W. Africa. Advised him to get a Transit instrument similar to that used by Capt Grant for moon culminating method.
William Christie, Astronomer Royal
RH says..... The transit instrument in question was made by Troughton & Simms, and the moon culminating method was used on Christie's advice on this occasion too - the survey of the Anglo-Portuguese boundary in eastern Africa in 1892.
