falling. At noon in Ponghon harbour it was blowing a fresh N gale which increased to a hard gale from the same direction in the evening but as yet the barometer was almost steady. The centre of the typhoon was perhaps situated in about 21%, 123° moving towards WNW.
On the morning of the 25th from observations made at Anping by Mr. A. W. BAIN we see that the centre of the disturbance had approached the coast of S Formosa. At Anping the barometer fell from 29.61 at 8 a. to 29.37 at 4 p., the wind being from N until 3 p. and blowing with almost typhoon, force between 1 p. and 3 p. At 4 p. the direction veered to NE and the force began to decrease with ising barometer. Between 7 p. and midnight a calm prevailed, but at the latter hour the wind came again suddenly from SE blowing fairly strong with the barometer rising rapidly. The centre was probably situated in 22, 121° at noon, ie., on the E Coast of S Formosa, In crossing the island it, no doubt, filled up considerably and the Anping observations indicate that the central area which passed near this station had scarcely cleared the island until midnight. The S.S. Ask was lying in Makung harbour (Pescadores) and a hurricane was experienced from N between noon and 9 p. when the force slightly decreased, the direction veering a little. The baronéter was at its lowest point at p. and it then rose slowly. At midnight they had NNE wind of force 10 and the barometer com- menced to rise quickly. At 5 a. on the 26th the direction had veered to SE, a moderate breeze. The centre therefore passed to the S of Makung near 2 a. on the 26th and it seemed to have already commenced to move in a WSW direction under the influence of the strong NNE winds blowing down the Formosa Channel.

The S.S. Niobe was situated in 23" 9', 118° 02′ at noon. They had barometer 29.75 with E & veering to ESE and SE as they progressed towards Hongkong. At Swatow the wind backed again to ENE and decreased to force 5 during the evening which indicates, together with observations made on board ship and at Hongkong, that the centre was moving towards SW while the depression was filling up and winds becoming light.
At noon on the 27th there was a trace of the depression in about 20o, 115° It then changed into an elongated trough-like depression lying from about 15o, 112o and through the Bashee Channel or thereabouts.
OCTOBER.
On the 28th at 11.15 a. Pressure is low in S Luzon." taoderate NE winds: cloudy, possibly some rain."
Forecast:-"barometer falling:
On the 31st at 10.30 a. "There is a depression in the China Sea to the S of Hongkong in about 15° to 16" latitude." At 11.0 a. Forecast:-"barometer unsteady: fresh to strong NE breezes: unsettled, wet."
On the 1st November at 11.15 a. "The shallow depression still lies in the China Sea to the S of" Hongkong." Forecast:-"barometer unsteady: fresh and strong NE breezes: cloudy, some drizzling rain.”
From October 26th to 29th pressure was decreasing generally on the China Coast from Hongkong to Shanghai and also in Luzon. On the latter date it was in defect to the extent of from 0.1 to 0.2 inch at Ilongkong (29.89) and at Shanghai (29.97), and the monsoon had become moderate and light along the coast and in the N part of the China Sea. At Manila (29.75) and Bolinao pressure was also about 0.1 inch below the normal and the winds at these two stations, which had been light from aN to E direction on the previous days, now became SE. At Cape St. James a light SW breeze prevailed.
The great decrease of pressure over N China, which appears to have been due to a depression lying over Manchuria on the 28th, caused the monsoon to become light on the China Coast from Shanghai southwards and also over the N part of the China Sea. The circumstances thus became favourable to the advance northwards of the S current and we know that on the 28th, light SW breezes had taken the place of the light NE winds which had previously prevailed at Cape St. James on the Cochin China Coast, while still farther south, in about 5°, 107, strong S and SW breezes prevailed on this day. It therefore seeins probable that a trough-like slight depression in which variable winds and cafus prevailed was formed in a belt lying across the China Sea and Philippine Archipelago in fron 10" to 12" lat, and that on the 29th this depression (XIV) had possibly become cyclonic to the SW of Luzon owing to the further advance northwards of S winds along the W Philippines.
