Erratic Track of a Barometric Depression

Abstract

THE singular course of the cyclonic system which has, during the week terminating on May 29, circulated round and across the British Isles, deserves more attention than can be thus early given to it. I wish here, with your permission, first, to describe the path of its centre as correctly as can be done with the data at present in my hands, mentioning at the same time the principal modifications of the isobars and of the weather in the neighbourhood of the centre; secondly, to mention some remarkable facts in relation to the upper currents as observed by myself in its neighbourhood; and finally, to indicate the nature of those questions an examination of which will, I believe, in the instance before me, prove to be of most scientific value.
