Descriptive Report. 129 Cheshunt.—Mr. W. C. Boyd, F.L.S, informs me that the shock was felt and a bell rung at " Arlesdene " (Mr. H. G. Wales). Hertford.—Shock felt slightly in some buildings. Kings Langley.—Mr. William Jones Loyd, J.P., reports that the shock was distinctly felt at " Langleybury " ; in a bed-room, china and movable articles were rattled, the bed curtains shaken, and the oscillation of the chair felt by a person seated ; time 9.20. St. Albans.—Mr. A. E. Gibbs, writing from the office of the ' Herts Advertiser,' informs me that the shock was felt in this town but slightly, and chiefly by persons in bed; no pictures, furniture, or other objects were displaced. Tring.—The Rev. F. W. Ragg, writing from Masworth Vicarage, Bucks, two miles north of Tring, has published the following valuable letter in ' Nature,' (May 8th, 1884, p. 32):- " This village lies partly on the lowest beds of the Chalk, and partly on the Gault; it is between N. lat. 51° 49' and 51° 50', and W. long. 0o 40' and 0° 41'.

This seemed to begin on the east, rather to north, and travelled westwards nearly. By shudder, I mean that a sort of vibration began which almost instantly increased in intensity, reached a climax, and then rapidly decreased and died away. It seemed to me to begin slightly north of east, because I remember feeling (for what reason I can hardly say) that the cause was hidden from me behind the east end of the church. I was on the south side, some eighteen feet from the south- east corner. A moment after a whirlwind followed, which began, as I find, near the top of the slope north-east of the church, and followed the churchyard wall which bends round the churchyard to south-west.
