Northumberland, England giants

The banks of the Cor being worn away by some impetuous land-floods, there was discovered, about the year 1660, a skeleton, conjectured to be that of a man, of extraordinary and prodigious size. The length of the thigh-bone was nearly six feet, and the skull, teeth, and other parts, proportionately monstrous: so that the length of the whole body was computed at 21 feet!

Some parts of it were in the possession of the Earl of Derwentwater, in 1693. A singularly large bone found here, was in the kitchen of the Old George Inn, in the flesh-market, New castle, for many years. The bone was purchased by the proprieter of the Keswick Museum, where it is shown as the rib of a giant Cor, found at Corbridge: beings for whom the Earth would seem unsuitable to tread upon.

But there is (an abundance) of evidence that mankind that mankind has degenerated in size.

History has given examples of gigantic human remains, progressively decreasing from 30 feet to 10 feet in height: living giants have seldom exceeded seven feet in height. . .
