In May, a small young hog.

In October, a female statue, of middling workmanship. Also a Silenus, a palm and three inches high, standing upon a square base raised upon three rows of steps, which are supported at the angles by lions claws. He has a bald head, a long curled beard, a hairy body, and naked feet. The drapery about him is loose and flowing: the fore-finger of each hand is extended, and all the rest are closed. From his back arises a branch above the head, where it divides into two, which, twisting their foliage round it, fall and spread themselves below the shoulders, on each of which a stand is placed to fix a lamp. In the middle, betwixt the extremities of these two small branches, is a bird resembling a parroquet. The whole of this figure is in a very good taste. All these things above-mentioned are of bronze.

In November was discovered a beautiful marble Terminus, of Greek workmanship, as big as the life. It is drest in a chlamys; has a young countenance; and the head is covered with a Grecian helmet.

Many other things have also been found, as lamps, vases, and such-like, in bronze. And we have often met with paintings. If any farther discoveries are made, which are remarkable, you may depend on being informed of them.

At present my time is much taken up, in a work extremely difficult and tedious; which is this: When the theatre was first discovered, there were found in it, among other things, several horses in bronze, larger than the life; but all of them bruised, and broken into many pieces. From this sad condition they are not yet restored. But his majesty having expressed a particular desire to see that effected, if possible, with regard to one of them, I resolved to attempt it; and accordingly have set about it.

IX. An Account of some Trees discovered under-ground on the Shore at Mount's-Bay in Cornwall: In a Letter from the Rev. Mr. William Borlase, F.R.S. to the Rev. Dr. Lyttelton, Dean of Exeter.

Ludgvan, Jan 24. 1757.

Reverend Sir,

Read Feb. 10, 1757.

BEING an airing the other day with Mrs. Borlase, on the sands below my house, we perceived the sands betwixt the Mount and Penzance much washed into pits, and bare stony areas, like a broken causey. In one of the latter, Mrs. B. as we passed by, thought she saw the appearance of a tree; and, upon a review, I found it to be the roots of a tree, branching off from the trunk in all directions. We made as much haste down to the same place in the afternoon as we could, and with proper help to make a farther examination. I measured and drew the remains; and about 30 feet to the west found the roots of another tree, but without any trunk, tho' displayed in the same horizontal manner as the first. Fifty feet farther to the north we found the body of an oak, three feet in diameter, reclining to the east. We dug about it, and traced it six feet deep under the surface; but its roots were still deeper than we could pursue them. Within a few feet distance was the body of a willow, one foot and a half in diameter, with the bark on; and one piece of a large hazel-branch, with its bark on. What the two first trees were, it was not easy to distinguish, there being not a sufficiency remaining of the first, and nothing but roots of the second, both pierced with the teredo, or augur-worm. Round these trees was sand, about ten inches deep, and then the natural earth, in which these trees had formerly flourished. It was a black marsh-earth, in which the leaves of the juncus were intirely preserved from putrefaction. These trees were 300 yards below full-sea-mark; and, when the tide is in, have at least 12 feet of water above them: and doubtless there are the remains of other trees farther towards the south, which the sea perpetually covers, and have more than 30 feet water above them. But these are sufficient to confirm the ancient tradition of these parts, that St. Michael's mount, now half a mile inclosed with the sea, when the tide is in, stood formerly in a wood. That the wood consisted of oak, very large, hazel and willow trees, is beyond dispute. That there has been a subsidence of the sea-shores hereabouts, is hinted in my letter to you, p. 92; and the different levels and tendencies, which we observed in the positions of the trees we found, afford us some material inferences, as to the degree and inequalities of such subsidences in general; as the age, in which this subsidence happened (near 1000 years since at least) may convince us, that when earthquakes happen, it is well for the country, that they are attended with subsidences; for then the ground settles, and the inflammable matter, which occasioned the earthquake, has no longer room to spread, unite, and recruit its forces, so as to create frequent and subsequent earthquakes: whereas, where there are earthquakes without proportionable subsidences, there are caverns and ducts under-ground remaining open and unchoaked, the same cause, which occasioned the first, has room to revive and renew its struggles, and to repeat its desolations or terrors; which is most probably the case of Lisbon. I am, Sir,
