It had blown exceeding hard, as I have already observ'd, for about fourteen Days past; and that so hard, that we thought it terrible Weather: Several Stacks of Chimnies were blown down, and several Ships were lost, and the Tiles in many Places were blown off from the Houses; and the nearer it came to the fatal 26_th_ of _November_, the Tempestuousness of the Weather encreas'd. On the _Wednesday_ Morning before, being the 24_th_ of _November_, it was fair Weather, and blew hard; but not so as to give any Apprehensions, till about 4 a Clock in the Afternoon the Wind encreased, and with Squauls of Rain and terrible Gusts blew very furiously. The Collector of these Sheets narrowly escap'd the Mischief of a Part of a House, which fell on the Evening of that Day by the Violence of the Wind; and abundance of Tiles were blown off the Houses that Night: the Wind continued with unusual Violence all the next Day and Night; and had not the Great Storm follow'd so soon, this had pass'd for a great Wind. On _Friday_ Morning it continued to blow exceeding hard, but not so as that it gave any Apprehensions of Danger within Doors; towards Night it encreased: and about 10 a Clock, our Barometers inform'd us that the Night would be very tempestuous; the _Mercury_ sunk lower than ever I had observ'd it on any Occasion whatsoever, which made me suppose the Tube had been handled and disturb'd by the Children. But as my Observations of this Nature are not regular enough to supply the Reader with a full Information, the Disorders of that dreadful Night having found me other Imployment, expecting every Moment when the House I was in would bury us all in its own Ruins; I have therefore subjoin'd a Letter from an Ingenious Gentleman on this very Head, directed to the _Royal Society_, and printed in the _Philosophical Transactions_, No. 289. P. 1530. as follows. _A Letter from the Reverend Mr._ William Derham, _F.R.S. Containing his Observations concerning the late Storm_. _SIR_, According to my Promise at the general Meeting of the _R.S._ on St. _Andrews_ Day, I here send you inclos'd the Account of my Ingenious and Inquisitive Friend _Richard Townely_, Esq; concerning the State of the Atmosphere in that Part of _Lancashire_ where he liveth, in the late dismal Storm. And I hope it will not be unaccepable, to accompany his with my own Observations at _Upminster_; especially since I shall not weary you with a long History of the Devastations, _&c._ but rather some Particulars of a more Philosophical Consideration.
