The letters of reference in the description answer to the same parts in fig. 1 5, 

 16, 17, and 18; but IQ, 20, 21, 22, are the figures of the stone, described in 

 this article, in all which the letters refer to the same lines.

A Collection of Various Papers presented to the R. S. concerning several Earth- 

 quakes, felt in England, and other Countries, in 1750 and other Years. 

 N° 496, p. 601, &c. 



About the year 1750 some earthquakes were felt in many parts of England, 

 indeed almost all over the country : and though no serious ill consequences at- 

 tended them, yet they produced a vast number of communications to the r. s. 

 stating the circumstances of them, from many dififerent parts of the country. 

 These accounts the Society collected, and printed all together, at the end of this 

 volume 46, forming the N° 497, being the last of this series of publication in 

 the form of N* by the Secretaries, on their own account. But, as may be ex- 

 pected, there being a general sameness or uniformity that runs through all these 

 accounts, such as loud rumbling noises, the shaking of the ground, the tottering 

 of houses, the rattling of the windows, and the furniture of houses, &c. which 

 circumstances may be all easily conceived ; it would be irksome and disgusting 

 to reprint such a number of tedious, and similar, and uninteresting accounts. 

 Instead of which therefore, we shall here give a summary of the whole in the 

 following table ; containing, in the 1st column, the date of the earthquakes; 

 in the 2d, the names of the persons communicating the accounts, with the 

 pages of the original vol. (46) where the accounts stand ; and in the 3d, the 

 places where the persons write from, or where the earthquake was felt. After 

 which, we shall advert to any particular circumstances, that may be more par- 

 ticularly deserving of that notice.
