Special observations of visibility were taken from the electrometer tower of the Colaba Observatory, about 50 feet from the ground," with a Bennett visibility meter at seven specified hours between sunrise and sunset, almost daily during November1936 to March 1939. Seven objects situated at different distances in different directions from the observatory were used and the data from these observations are discussed for monthly variations. For hourly observations on selected days' and nights, fourteen objects at different directions and distances and five city lamps towards north, were mainly observed with the Bannett and a Wigand meter. Typical hourly observations are discussed and shown diagrammatically. Wind and associated visibility are statistically analysed.
