“ I send you some Wind and Barometer readings for Poona regarding the Hurricane, which
want of leisure prevented my doing before.
The wind readings you may depend on, being taken fronr a self-registering Anemometer.
The Barometer readings were unfortunately at long intervals, but are reliable as far as they go.
I have not beside me your resume as given in the Times, but your Barometer began to sink at
10 p. m * on the night of the 1st, and to rise about 5 a. m. next morning, our fall commenced
at the same hour, but did not recover itself unlil mid-day of the next—and being on the out
skirts the fall was trifling, as we were out of the burst of it. As to wind while you went from
the E. points by the N. momentarily and back S. E. and as the Cyclone veered off to Western,
and at Poona the wind was nearly directly contrary, changing from E. and 8. E., to N. W. and
W. S. W., where it remained when the hurricane blew over.

been lowest at 5 a. m., rising in Bombay,
falling still in Poona.
That a vast cylinder or disk of air should have been so suddenly set into
such violent motion, and come so quickly and quietly to rest,—stopping short
in its career at once, without any apparent retarding cause, any diminution of
energy or speed, or any communication of its momentum to any other body, is a
thing so inconsistent with all recognised laws, that it would seem inexplicable
but for a theory, for which I believe we are indebted to Mr. Piddington. The
The Barometer appears to me to have begun to sink at 9 a. m. on the 1st, and though it
rose again from 4 p. m. till 8, the descending tide was *179 betwixt the first two of these hours,
the re-ascending one only -007 a quantity barely perceptible amounting in reality a virtual fall
of-063 the rise due to November being’070, that of the previous descent 'llfi. The mercury
then in 11 hours falling steadily by no less than *123, and this accompanied by the Other signs
seem to me warning enough of the approach of the storm.
