Hourly Readings of Tides in 1887 and 1888.

The following hourly readings of tides, expressed in hundredths of a foot were obtained by aid of Sir WILLIAM THOMSON'S automatic tide-gauge, which was mounted in a hut in the boat basin belonging to the Police Station at Kowloon Point. This basin is situated in the south-western corner of the peninsula of Kowloon and occupies therefore a central position in the harbour of Hongkong. The waves are not much felt in this basin as the prevailing wind and waves come from the East.

At the bottom of the monthly tables are shown the mean monthly readings for the twenty-four hours. The readings for Mean Sea Level were deduced from them as follows:-
