A. Experiments upon the force requisite to twist off cast iron necks show that if the cube of the diameter of neck in inches be multiplied by 880, the product will be the force of torsion which will twist them off when acting at 6 inches radius; on this fact the following rule is founded: To find the diameter of a cast iron fly wheel shaft: multiply the square of the diameter of the cylinder in inches, by the length of the crank in inches, and extract the cube root of the product, which multiply by 0.3025, and the result will be the proper diameter of the shaft in inches at the smallest part, when of cast iron.

As to the soil, I may say that in some respects it is poorer than yours, but in others not so poor. The amount of plant food contained in six and two-thirds inches of the surface soil of an acre, representing two million pounds of soil, are as follows: 2,880 pounds of nitrogen 840 pounds of phosphorus 24,940 pounds of potassium 6,740 pounds of magnesium 14,660 pounds of calcium

Blackley gives two tables, showing the average number of pollen grains collected in twenty-four hours on one square of glass, between May 28 and August 21, in both a rural and an urban position. The maximum both in town and country was reached on June 28, when in the town 105 pollen grains were deposited, and in the country 880 grains.

He thought himself safe from his enraged father there, but the latter quickly returned to Fostât, and the news of the ample preparations which he was hastening for the subjection of his rebel son caused El-Abbas to place himself still farther out of his reach. The neighbouring Berbers gave Ibrahim their assistance, and Abbas was defeated and retreated to Barca in 880.

In a word, if we speak of the territorial acquisitions, which were the result of the victories obtained by means of the extraordinary resources created by the men of science, France has acquired an extent of 1,498 square leagues, and a population of 4,381,266 individuals; namely, Savoy, containing 411,700 inhabitants; the County of Nice, 93,166; Avignon, the Comtat Venaissin, and Dutch Flanders, 200,500; Maestricht and Venloo, 90,000; Belgium, 1,880,000; the left bank of the Rhine, 1,658,500; Geneva and its territory, 40,000; and Mulhausen, 7,200.

Captain Servadac applied himself to his task while the by-standers waited, with some difficulty suppressing their inclination to laugh. There was a short silence, at the end of which Servadac announced that the volume of the comet was 47,880,000 cubic miles. "Just about 5,000 times less than the earth," observed the lieutenant. "Nice little comet! pretty little comet!" said Ben Zoof.

Its chief record, however, is that of being the type fitted to the Vickers-Vimy aeroplane which made the first Atlantic flight, covering the distance of 1,880 miles at a speed averaging 117 miles an hour.

While Theopompos quite preposterously brings him down as late as the twenty-third Olympiad, Krates removes him to the twelfth century B. C. The date ordinarily accepted by modern critics is the one assigned by Herodotos, 880 B. C. Yet Mr. Gladstone shows reasons, which appear to me convincing, for doubting or rejecting this date.

Other authorities give, the more recent date of b.c. 880 as that of the events recorded in it. This chronology will suggest an important reflection later on. The wonderful story of Jonah and the whale begins in this wise: "Now the word of the Lord came unto Jonah, the son of Amittai, saying, Arise, go to Nineveh, that great city, and cry against it; for their wickedness is come up before me."
