We observe further, that the main of this second earthquake display'd its effects along, and between the two rivers, _Welland_ and _Avon_: and _that_ from their very origins, down to their fall into the sea. It likewise reach'd the river _Witham_, which directed the electric stream that way too, to _Lincoln_. For which reason, as there meeting the same coming from _Boston_, the shock was most sensibly felt. It reach'd likewise to the _Trent_ at _Nottingham_, which convey'd it to _Newark_. The first electrical stroke seems to have been made on the high ground above _Daventry_, in _Northamptonshire_; where the _Roman_ camps are, made by _P. Ostorius_ the proprætor. From thence it descended chiefly eastward, and along the river _Welland_, from _Harborough_ to _Stamford_, _Spalding_, the sea: and along the river _Avon_, or _Nen_, to _Northampton_, _Peterborough_, _Wisbech_ to the sea. It spread itself all over the vast level of the isle of _Ely_; further'd by very many canals, and rivers, natural, and artificial, made for drainage. It was still conducted eastward up _Mildenhall_ river, in _Suffolk_, to _Bury_, and the parts adjacent. All this affair duly consider'd, is a confirmation of the doctrine I advanc'd on this subject. 10ly, I apprehend, it was not the noise in the air, as of many cannon let off at once, preceding the earthquake, that so much affrighted people, or affected the sheep, the rookery at _Kensington_, the hen and chickens in _Gray's-inn-lane_, the pigeons. It could not be barely the superficial movement of the earth, that disturb'd them all at once. I judge it to be the _effect_ of electricity, somewhat like what causes sea sickness; such a sort of motion, as we are not accustomed to. So the earthquake affects all those of weak nerves, or that have nervous complaints; obnoxious to hysterics, colics, rheumatick pains in their joints; several women were seized with violent head-achs, before both the shocks we felt in _London_. It was this that gave the people a shortness of breath. Mr. _Smith_ from _Peterborough_ speaks of a person that found himself very sick upon it. This made the dog run whining about the room, seeking to get out: this made the fishes leap up in the pond at _Southwark_; like as the experiment of electrifying the fishes: it makes them sick. And this causes the birds in cages to hide their heads under their wings, because they cannot fly away. Which is commonly observ'd of them in _Italy_, and countries, where earthquakes are more frequent. 11ly, I observe, the shepherd at _Kensington_ thought the motion of the earthquake, and the sound, was from the north-west to south-east; the like Mr. _W. Smith_ from _Peterborough_. On the contrary, Mr. _Byfield_ the scarlet dyer in _Southwark_, thought the noise came from the river below bridge, and went toward _Westminster_; where it rattled so, that he did not doubt, but that the abbey-church was beaten down.
