Historical Introduction. 11 at Newchurch, and the wall of Haslingden railway-station reported to have been slightly cracked. Slighter shocks on March 17th in E. Yorkshire, and on the 25th at Manchester, &c. (' Times,' March 16th, 17th, 19th, and 29th, 1869.) 1881. August 26th, about noon. Teversal, Nottingham- shire, and at Tackley. Slight damage to a chimney and ceiling. (' Times,' Aug. 30th, 1881.) As will be seen from the foregoing catalogue, many shocks of apparently great destructiveness have from time to time been recorded, but the early accounts are most probably exaggerated, and are certainly too vague to admit of any fail- estimation of their severity. It is only where specific accounts of the damage to cathedrals, churches, and other buildings have been handed down, that there is some means of approximately judging of the intensity, and estimated by this standard the earthquakes of 1185, 1246, 1248, 1275, 1382, and 1480, appear to be the only ones which admit of comparison with that of April 22nd, 1884; or, in other words, since authentic records were kept, there have been but six earthquakes in Britain which may have equalled or exceeded in intensity that which forms the subject of the present Report. But although Essex had previous to last April been exempt from destructive shocks, there are some few records of earthquakes originating elsewhere, which in former times made themselves felt in our county. As a contribution to local history, it will be of interest to give these records here in chronological order. In 1692 (Sept. 8th, between 2 and 3 p.m.), there occurred a severe earthquake in Europe, which was felt in some parts of Kent, Middlesex (London), Essex, Suffolk (Ipswich), Norfolk (Norwich), &c. In Essex there are records from Colchester and Coggeshall, which are given below in extenso :— " On Thursday, Sept. 8, 1692, there happened about two of the clock in the afternoon, for the space of a minute or more, an universal earthquake all over England, France, Holland, and some parts of Germany. And particularly it was attested to me by the masons that were there
