"It was during the siege of Methone that Philip had the misfortune to lose on of his eyes. A random arrow discharged from the rampart fell square in the king's face and destroyed one-half of his sight. When the arrow-head was drawn away, it was found to contain the following label: "Astor to Philip's right eye." It appeared on inquiry that the unerring missile had been discharged by an offended archer who has recently offered his services to the king and been rejected. He hd represented to Philip that his skill with the bow was great that he could kill a small bird on the wing. The king not believing the story had put off the applicant with the remark, "Well, well, I shall make use of thee when I go to war with the starlings." Astor has then joined the Methoneans and now vindicated his skill in a way never to be forgotten."—Ridpath, 1885

"The pyramids of Egypt are well entitled to a place among the most interesting curiosities in the world. The principal ones stand opposite Cairo, on the west side of the river Nile. They are built of stones, which overleap each other, and thus form steps from the bottom to the top. The perpendicular height of the largest is about 500 feet, and the area of its basis contains nearly 500,000 square feet, or something more than eleven English acres of ground."—Blake, 1825

"The present structure, begun in 1163 and completed about 1240, suffered severely during the French Revolution, when it was converted into a Temple of Reason. Extensive renovations and alterations were made during the nineteenth century. Two massive square towers, originally intended to support spires, crown the principle or western façade. Its three doors are surrounded by elaborate sculptures and surmounted by a row of figures representing twenty-eight kings of Israel and Judah. Above the central door is a rose window of stained glass and above this is a graceful gallery of painted arches supported on slender columns."

Hydrostatics is a branch of hydrodynamics that deals with the statics of fluids that are usually combined to an equilibrium and pressure of liquids. Image a is a vessel with a wooden block of the same size and image b, which has the same dimensions as image a, is filled with water and has a depth the same length as the wooden block. The pressure per square inch would be 100/10 = 10

A reef knot is formed by taking an overhand knot and repeating the overhand knot process (pass one end of the line over the line, pass the line around, then feed the line through the loop) with the opposite end of the line (Fig. 1): if two overhand knots are made the same way, the result will be a 'granny' (Fig. 2).

Lamium album (also known as the white dead-nettle, or archangel) is a member of the Lamium, a genus of Labiatæ, whose flowers are marked by possessing four stamens longer than the corolla tube, a bell-shaped calyx with five teeth, and a two-lipped corolla, the upper lip being arched, the lower trifid and spreading. It has been naturalized in America and has a square stem and white flowers with black stamens.

A Lemniscate is, in general, a curve generated by a point moving so that the product of its distances from two fixed points is the square of half the distance between the points. It is a particular case of the Cassinian oval and resembles a figure 8. When the line joining the two fixed points is the axis of x and the middle point of this line is the origin, the Cartesian equation is the fourth degree equation, (((x^2)+(y^2))^2)=2(a^2)((x^2)-(y^2)). The polar equation is (ℽ^2) = 2(a^2)cos(2θ). The locus of the feet of the perpendiculars from the center of an equilateral hyperbola to its tangents is a lemniscate. The name lemniscate is sometimes given to any crunodal symmetric quartic curve having no infinite branch. The name is also sometimes given to a general class of curves derived from other curves in the way that the above is derived from the equilateral hyperbola. With these more general definitions of the lemniscate the above curve is called the lemniscate of Bernoulli.

"A small fore-and-aft rigged vessel with one mast, generally carrying a jib, fore-staysail, mainsail, and gaff-topsail. Some sloops formerly had a square topsail. It is generally understood that a sloop differs from a cutter by having a fixed instead of a running bowsprit, but the names are used somewhat indiscriminately." —Whitney, 1889
