Davison : Yorkshire Earthquakes.

mentioned above or from their own recollection, of earthquakes 

 felt in any part of the country, but especially in Yorkshire, such 

 help would, I need hardly say, be of the very greatest service. 



Except in the West Riding-, and especially in the district 

 bordering on Lancashire, earthquakes are comparatively rare in 

 Yorkshire. The following is a list of those known to me since 

 the beginning of the 19th century, dates printed in italics being 

 those of earthquakes which were probably sensible in the 

 county, but of which I possess no actual records : — 



Riding Unknown. — 20th March 1822, i6th and 17th March 

 1869, 22nd March 1871. 



East Riding. — 30th April 1818, I'^th March 184^^ gth Nov. 

 1852, 6th Oct. 1863, 15th March 1869, iSth June 1885, 17th 

 Dec. 1896, 24th March 1903, and 3rd July 1904. 



North Riding. — I'/th March 184J, gth Nov. 18^2, 6th Oct. 

 1863, 17th March 1871, 23rd Sep. 1875, ^5^^ June 1890, 17th 

 Dec. 1896, 24 March 1903, and 3rd July 1904. 



West Riding. — 17th March 1816, 9th Nov. 1817, 9th Feb. 



and 1827, 1 2th July 1834, loth and lyth March 184J, 9th 



Nov. 1852, 15th Dec. 1859, 1861, 6th Oct. 1863, 26th 



Sep. 1864, joZ/z Oct 1868, 15th March 1869, 17th March 1871, 

 4th Jan. 1872, 29th and 30th April 1873, 27th April 1874, 23rd 

 and 25th Sep. 1875, 22jid April 1884, i8th June 1885, 15th 

 Sep. 1886, loth Feb. 1889, 25th and 26th June 1890, 17th Dec. 

 1896, 24th March 1903, and 3rd July 1904. 



Notes about any of the above earthquakes, except perhaps 

 the last three, would be most useful for the purpose which 

 I have in view ; but I should be especially glad to receive 

 accounts of those which occurred on 17th March 1843, 9th 

 Nov. 1852, 6th Oct. 1863, 30th Oct. 1868, 15th March 1869, 

 17th March 187 1, and 22nd April 1884. Notices of the effects 

 of the great Lisbon earthquake of 1755, if any such were 

 observed, would also be of considerable interest. 



The points on which I desire most to obtain information are 

 indicated in the appended questions. I may add that I shall be 

 glad to send printed copies of these questions to anyone who 

 may be able and willing to give, to however slight an extent, 

 the valuable assistance indicated in this note. 



Questions. 



1. — Place of observation. 



2. — Condition of observer when the earthquake began, (a) in- 



doors or outside, (b) awake or asleep.
