 this diagram, the “Idaho” at her anchorage in the harbour being marked on the N. N. E. part of the circle.

As most of you here present were in Yokohama at the time when this typhoon passed over the place it will not be necessary to dwell long on the details of it, especially as there was nothing very remarkable about it. I will merely mention such of the principal facts as may be of interest to those of you who had no opportunity of observing them for yourselves.

Thus: at 4 the gale commenced with the wind at E. S. E., blowing with a force of from 6 to 9; barometer 29.28; thermometer 80; weather, o. c. q. r. n.; clouds, cumulus-nimbus; sea m.

At 5, wind E. S. E., force from 9 to 10; barom. 29.14, having fallen 0.14 inch during the hour; therm. weather and clouds the same; sea c. r. At 6 E. S. E. $1⁄4$ E., force 9 to 11; barom. 28.94, having fallen 0.20 during the hour; therm. 78, at 7 E.S.E.$1⁄2$ E., force 11$1⁄2$. This was a fearful blast which lasted about five minutes; had it continued for any length of time great damage both on shore and in the bay would have been the inevitable results. Even during the short time it did last two vessels were started from their anchorage and driven rapidly before the fury of the blast. One, a small steamer, which in her course fouled a native junk and sunk her; the other, a British barque, drifting at the rate of about five or six knots in a W. N. W. direction towards the Kanagawa shore where she would surely have brought up had the wind continued for half an hour, or even 20 minutes longer. Barom. at 7 28.50 having fallen O.44 inch during hour. At 7.05, however, the blast was over and the wind began to veer to the southward.

At 7.15, barometer 28.35, having fallen 0.15 inch in 15 minutes, wind S. very light, the rain and squalls had ceased and an entire calm followed. At 7.30 barometer had reached its lowest stand 28.27, having fallen 0.08 inch during the 15 minutes, and at that time I compute the centre to have passed over the “Idaho”; the calm lasted for nearly half an hour. At 7.45 light airs were felt from
