Christian Henry Heinecken, born at Lubeck, in 1721, spoke his mother tongue fluently at ten months of age; at one year old he knew the principal events of the Pentateuch; in two months more he was master of the entire histories of the Old and New Testaments; at two years and a half he answered the principal questions of geography, and in ancient and modern history. He spoke Latin, French, German, and Dutch with facility before the commencement of his fourth year. His constitution was so delicate that he was not weaned till a few months before his death which occurred in 1725.

In his 1902 geology of Oregon’s Crater Lake, Joseph Diller mentioned that he’d seen a great stump bobbing vertically in the lake six years earlier, in 1896.

It’s still there. Apparently the lake is so cold that it’s preserved the 30-foot stump for more than a century. And the “old man” is pretty spry: In 1938, when the sketch above was made, the log wandered more than 62 miles in one three-month period.

In the course of some structural alterations to an ancient house near Edinburgh three unknown rooms were brought to light, bearing testimony of their last inmate. One of them had been occupied as a bedroom. The clothing of the bed was disarranged, as if it had been slept in only a few hours previously, and close by was an antique dressing-gown. How interesting it would be to know some particulars of the sudden surprise which evidently drove the owner of the garment from his snug quarters — whether he effected his escape, or whether he was captured! The walls of this buried chamber, if they could speak, had some curious story to relate.

A curious account of a subterranean garden formed at the bottom of the Percy Main Pit, Newcastle, by the furnace-keeper, was lately communicated to the Caledonian Horticultural Society. The plants are formed in the bottom of the mine by the light and radiant heat of an open stove, constantly maintained for the sake of ventilation. The same letter communicated an account of an extensive natural hot-bed near Dudley, in Staffordshire, which is heated by means of the slow combustion of coal at some depth below the surface. From this natural hot-bed, a gardener raises annually crops of different kinds of culinary vegetables, which are earlier, by some weeks, than those in the surrounding gardens.

This is a correct sketch of the sea-serpent seen by me while on board the ship Sacramento, on her passage from New York to Melbourne, I being at the wheel at the time. It had the body of a very large snake; its length appeared to me to be about fifty feet or sixty feet. Its head was like an alligator’s, with a pair of flippers about ten feet from its head. The colour was of a reddish brown. At the time seen it was lying perfectly still, with its head raised about three feet above the surface of the sea, and as it got thirty or forty feet astern, it dropped its head.

Hypothermia victims are often found with clothing removed, as if they’ve been assaulted. It’s not clear why a freezing person would undress; possibly their judgment is impaired, and possibly exhaustion brings a sensation of warmth to the skin.

Sir Henry Blackman, of Lewes, on being knighted in 1782, gave a dinner to sixteen friends, with an invitation to them to dine with him annually for forty years; four of them died during the first four years, but twenty-eight years rolled round before another seat became vacant at the festive board. In 1814 two died, aged between eighty and ninety; so that ten remained of the original number at the thirty-third anniversary, held in July, 1815!
