169⁸/₉. was a terrible Storm that did much damage. This I number 10 degrees; the Wind then W.N.W. vid. Ph. Tr. No. 262. Another remarkable Storm was Feb. 3. 170¹/₂. at which time was the greatest descent of the ☿ ever known: This I number 9 degrees. But this last of November, I number at least 15 degrees.

As to the Stations of the Barometer, you have Mr. Towneley's and mine in the following Table to be seen at one View.

A Table shewing the Height of the Mercury in the Barometer, at Townely and Upminster, before, in, and after the Storm

As to November 17th (whereon Mr. Towneley mentions a violent Storm in Oxfordshire) it was a Stormy Afternoon here at Upminster, accompanied with Rain, but not violent, nor ☿ very low. November 11th and 12th had both higher Winds and more Rain; and the ☿ was those Days lower than even in the last Storm of November 26th.

Thus, Sir, I have given you the truest Account I can, of what I thought most to deserve Observation, both before, and in the late Storm. I could have added some other particulars, but that I fear I have already made my Letter long, and am tedious. I shall therefore only add, that I have Accounts of the Violence of the Storm at Norwich, Beccles, Sudbury, Colchester, Rochford, and several other intermediate places; but I need not tell Particulars, because I question not but you have better Informations.

Thus far Mr. Derham's Letter.

It did not blow so hard till Twelve a Clock at Night, but that most Families went to Bed; though many of them not without some Concern at the terrible Wind, which then blew: But about One, or at least by Two a Clock, 'tis suppos'd, few People, that were capable of any Sense of Danger, were so hardy as to lie in Bed. And the Fury of the Tempest encreased to such a Degree, that as the Editor of this Account being in London, and conversing with the People the next Days, understood, most People expected the Fall of their Houses.

And yet in this general Apprehension, no body durst quit their tottering Habitations; for whatever the Danger was within doors, 'twas worse without; the Bricks, Tiles, and Stones, from the Tops of the Houses, flew with such force, and so thick in the Streets, that no one thought fit to venture out, tho' their Houses were near demolish'd within.

The Author of this Relation was in a well-built brick House in the skirts of the City; and a Stack of Chimneys falling in upon the next Houses, gave the House such a Shock, that they thought it was just coming down upon their Heads: but opening the Door to attempt an Escape into a Garden, the Danger was so apparent, that they all thought fit to surrender to the Disposal of Almighty Providence, and expect their Graves in the Ruins of the House, rather than to meet most certain Destruction in the open Garden: for unless they cou'd have gone above two hundred Yards from any Building, there had been no Security, for the Force of the Wind blew the Tiles point-blank, tho' their weight inclines them downward: and in several very broad Streets, we saw the Windows broken by the flying of Tile-sherds from the other side: and where there was room for them to fly, the Author of this has seen Tiles blown from a House above thirty or forty Yards, and stuck from five to eight Inches into the solid Earth. Pieces of Timber, Iron, and Sheets of Lead, have from higher Buildings been blown much farther; as in the Particulars hereafter will appear.

It is the receiv'd Opinion of abundance of People, that they felt, during the impetuous fury of the Wind, several Movements of the Earth; and we have several Letters which affirm it: But as an Earthquake must have been so general, that every body must have discern'd it; and as the People were in their Houses when they imagin'd they felt it, the Shaking and Terror of which might deceive their Imagination, and impose upon their Judgment; I shall not venture to affirm it was so: And being resolv'd to use so much Caution in this Relation as to transmit nothing to Posterity without authentick Vouchers, and such Testimony as no reasonable Man will dispute; so if any Relation come in our way, which may afford us a Probability, tho' it may be related for the sake of its Strangeness or Novelty, it shall nevertheless come in the Company of all its Uncertainties, and the Reader left to judge of its Truth: for this Account had not been undertaken, but with design to undeceive the World in false Relations, and to give an Account back'd with such Authorities, as that the Credit of it shou'd admit of no Disputes.

For this reason I cannot venture to affirm that there was any such thing as an Earthquake; but the Concern and Consternation of all People was so great, that I cannot wonder at their imagining several things which were not, any more than their enlarging on things that were, since nothing is more frequent, than for Fear to double every Object, and impose upon the Understanding,
