IV. A letter from Mr. Ralph Thoresby, F. R. S. to Sir Hans Sloane, Bart. President of the College of Physicians, and Vice-Pres. R. S. concerning the effects of a violent shower of rain in Yorkshire

The Effects of a violent Shower of Rain at Riponden, near Halifax, were so surprizing, that I wrote to a Gentleman in those Parts for an Account that might be depended upon; and particularly desired to know, whether there was not an Eruption of Waters out of the Hills, as the late ingenious Mr. Townley to Townley wrote me there was out of Pendle-Hill, in that at Star-bottom mentioned in the Philos. Trans. No 245. but all the Account I can learn of this is, that what they call the Dashing of two great watery Clouds upon the Hills, occasioned the Inundation; what ever was the more immediate Cause, the Effects were dismal, and so sudden, that tho’ it was upon the Daytime, the poor Creatures could not save their Lives.
