Philosophical Transactions/Volume 54/An Account of a remarkable Tide at Bristol
Read Feb. 23,
At Rownham Passage, a mile below the city, the ferry-men observed the tide to ebb almost instantaneousy, and to sink at least four feet perpendicular. Then it flowed in again, as it should have regularly done.
Ar King-Road, which is about three miles below the city, the officers observed the king's boat to float suddenly, which they attributed to a great fresh comming. But they found afterwards the boat presently aground.
I could get no intelligence of any thing observable, that happened in the river Severn, excepting that at Gloucester, and at Worcester, the inundation sunk very fast on that day. But most undoubtedly the strong rapid tide of the Severn must have been affected in a very remarkable manner, had there been any curious persons to take notice of it.
