By moving the wires from the battery up and down outside the pile of helices, it was clear that an upward and downward movement of the rod would follow, 'and that a shackle-bar attached from this oscillating rod, and to a crank, would convert this reciprocating motion into a continuous one. To this contrivance the name of 'Jumper' was given, of which one was exhibited, the helices weighing 800 lbs., and the rod 526 lbs.; and by the means above mentioned, it has been converted into a working-engine, with a twelve-inch crank, and a fly-wheel of four and a half feet in diameter.
The people who came with Sheakondo to our bivouac had their teeth filed to a point by way of beautifying them, though those which were left untouched were always the whitest; they are generally tattooed in various parts, but chiefly on the abdomen: the skin is raised in small elevated cicatrices, each nearly half an inch long and a quarter of an inch in diameter, so that a number of them may constitute a star, or other device.
The mouth into which the fall pours was, as near as I could guess, about one hundred feet in diameter north and south and about two hundred feet east and west, which is about the shape and size of the fall at its best in its normal condition at this season. The crater-like opening was not a true oval, but more like a huge coarse mouth.
Beyond this the hill receded, forming a nearly circular basin a mile in diameter, from the sides of which the rocks ascended almost perpendicularly, so that the only means of entering it was through the gorge.
I think you will agree with me, that it must have taken some time for the skeletons of animalcules of a hundredth of an inch in diameter to heap up such a mass as that. I have said that throughout the thickness of the chalk the remains of other animals are scattered. These remains are often in the most exquisite state of preservation.
Williams, might perhaps be paralleled at the present time; and many elms, transplanted, at a diameter of six inches, within the memory of persons still living, measure four and sometimes even five feet through.
If the moon is represented by an illuminated disc of one foot in diameter, it will, when looked at at a distance of 115 feet, have the same visual size as the moon itself, but if your seat is nearer the scene it will look too large, if further off it will look too small.
The border of Thebit rises at one place on the N.W. to a height of nearly 10,000 feet above the interior, which includes much detail. The E. wall of Thebit A attains the same height above its floor, which is depressed more than 5000 feet below the Mare. BIRT. This ring-plain, about 12 miles in diameter, is situated on the Mare Nubium, some distance due E. of Thebit.
Experiments on animals with Quaternary flint implements have always been successful, and have had no tragic results, which is the best proof we can possibly give. The size of the perforations made varies ad infinitum. One, the largest known, is described which is no less than sixteen inches in diameter.
The corolla itself is a gold-colored cup a foot in diameter, lily-like in a general way, but with a large pestle-shaped ovary rising in the centre of the flower, in which are planted a number of large seeds, the 'pins' of Wampapin.
