880 THE HONGKONG GOVERNMENT GAZETTE, 13TH OCTOBER, 1894.
typhoon can be almost certainly put down from these observations as in lat. 19° ()′ N, long. 118° 0′ E., giving it a motion of about 230 miles, direction W by N in the 24 hours. The wind direction at Bolinao being SSE, and remaining steadily at this point for several hours indicates that the position given is rather too much to the North, and as the typhoon was now much nearer Bolinao than Hongkong, it seemed just to give this station the greater weight, and the position marked in our maps at this time is lat. 18° 0′ N, long. 117° 30′ E, or 250 miles W by S of the position 24 hours earlier. The notice issued at 11.15 a.m. in conformity with these remarks was: "the depression "appears to have moved westward since yesterday, and to be now situated to the W of N Luzon. "Red drum hoisted."
At 4 p.m. on the same date the barometer had risen (0.03 inch at Bolinao, and fallen 0.01 inch only at Hongkong, the former shewing that the disturbance was receding slowly from Bolinao, and approaching Hongkong still more slowly, or pursuing the W by S course indicated in the morning. This opinion is strengthened by the backing of the wind at Bolinao to SE; but the position of the typhoon is now as near to Hongkong as to the last mentioned place, and a more detailed account of our local observations becomes necessary.
The following table gives the height of the barometer, corrected for temperature and daily tide and reduced to Mean Sea Level for each hour, the direction and velocity of the wind as registered by the anemometer, and the times at which notices were issued:
