Extract

The most remarkable earthquakes of the year 1890 were those felt in the district round Inverness between November 15 and December 14. These have been described in a separate paper. The remaining earthquakes were of comparatively slight intensity. Two or three were felt during the night of June 25–26 within a very small area to the north-east of Leeds, and one at least in Kintyre on July 24. Several slight shocks at Invergarry and Feddan, in Inverness-shire, complete the list so far as known to me, with the exception of a doubtful shock at Tulliallan in Perthshire on January 6.

It is hardly necessary to do more than refer here to the two supposed earthquakes felt on January 7 at and near Chelmsford. In a letter to “Nature,” I have given the evidence in full; and it appears to me sufficient to show that they were merely the reports of one of the great Woolwich guns.

page 454 note 1 At both places, the shocks are recorded by only one observer, and should therefore, strictly, be regarded as doubtful shocks; but I have placed them under a separate heading, as both observers have for several years diligently recorded the occurrence of every shock felt by them.
