The stem of this specimen is so intirely divested of its yellow mealy covering, that we may easily trace the manner in which the animals, that compose it, have carried up their stony tubular cells, which lie side by side along the surface. These tubes have still some marks of sponginess at particular distances, which, as they come to join together, form those irregular cross-lines, that surround the stem in several places. _See Fig._ A. In other specimens I have observed the principal stems covered over with calcarious tubes, such as I have described in the Essay on Corallines, _&c._ in that species of keratophyton called Venus’s Fan. _Plate 26_. The sponginess of the knobby joints occasions that excessive brittleness in the lesser branches; which accounts for the difficulty, which Rumphius mentions, of getting good specimens of this beautiful coral. I have lately seen a white pipy and stony coral with spongy knobs, which is only a different species of this genus, in the very curious cabinets of our friends Dr. John Fothergill, M. D. and Mr. Isaac Romilly, F.R.S. specimens of which they have both lately received from the East Indies. The examining of these has given me an opportunity to be more particular in the description of this coral; which seems to point out to us the great affinity there is between corals, keratophyta, and sponges. I am, Dear Sir, Your most affectionate humble Servant, John Ellis. Laurence Lane, Mar. 24, 1757. XXIV. _An Account of the Effects of a Storm at_ Wigton _in_ Cumberland. _Communicated by Mr._ Philip Miller, _F.R.S._ _To the Rev._ Tho. Birch, _D. D. Secr. R. S._ [Read Mar. 31, 1757.] SIR, I Received the inclosed letter by the post, giving an account of the storm, which happened lately in the north. If the Royal Society have not already been informed of the effects of it, and you think the contents of it worthy their notice; I beg you will be so good as to communicate it to them. The facts therein mentioned have been confirmed to me by a person of skill and integrity. Mr. Thomlinson’s conjecture of the cause of the leaves of trees appearing scorched after the storm, I believe to be true; having two or three times myself observed the same in Sussex, at a considerable distance from the sea; when all the hedges, trees, and woods, on the side toward the sea, have had their leaves scorched, as if fire had passed over them; and their opposite sides from the sea have continued in full verdure; which frequently happens in storms from the south-west: and, upon tasting their leaves, I have found them as salt, as if they had been steeped in brine. I am, SIR, Your most obedient humble Servant, Philip Miller. Chelsea, Nov. 23. 1756. _To Mr._ Philip Miller. Wigton, Nov. 15. 1756. +SIR,+
