"About forty miles northwest of Charleston, near the line between Charleston and Orangeburg counties, are some wonderful springs. The water boils up from the ground, clear and pure. It is a subterranean river that appears upon the surface, and that winds through the lowlands northwest for about two miles, and empties into the Santee at Nelson's Ferry."—Coffin, 1879

"Below the pictured hieroglyphics in the first line is the same text in a simpler writing known as hieratic. The two systems, however, were not distinct; they were as identical as our own printed and written characters. The third line illustrates old Babylonian cuneiform, in which the characters, like the hieroglyphics, are rude and broken down pictures of objects. Derived from them is the later cuneiform shown in lines four and five."—Webster, 1913

An illustration of what it would look like if ball e that is placed in a cup attached to lever o were to be pushed out by using a swinging arm activated by spring d. Spring d is arranged in a manner that when it is drawn back and released, it will strive lever o and ball b at the same time. In the experiment, ball b follows the curved line and ball e is dropped vertically. Both will meet the floor at the same time. This experiment is meant to show how Newton's second law works. The acceleration of a body is parallel and directly proportional to the net force and inversely proportional to the mass. F = ma

Gepyrea is a name formerly given to a class of worms which included three families: (1) Priapulidae; (2) Sipunculidae; (3) Echiuridae. The three families have little in common, and the class Gephyrea has ceased to exist in strict systematic zoology. This illustration shows and example from each of the three families: (1) Priapulus caudatus; (2) Sipunculus nudus; (3) Echiurus Pallasi.

(1.) The guillotine is an instrument employed for the purpose of decapitation. It was officially introduced into France as the means of inflicting capital punishment in April, 1792. It was named after its reputed inventor, Dr. Joseph Ingace-Guillotin, who, contrary to popular belief, died a natural death, and not a victim of his own invention. The instrument consists of two upright posts held together at the top by a cross beam, the former being perpendicularly so grooved as to allow of the falling in a direct line a broad steel blade, whose edge is cut obliquely. The latter, sometimes weighted with lead, descends upon the neck of the criminal immediately after the cord which holds it up is released by the executioner. (2.) A guillotine is a machine, similar in name and in general construction to the above, employed by bookbinders. It is used for cutting paper and trimming the edges of books after the sheets have been sewn together.

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).

To tie a bowline knot, lay the end of the rope 'a' over 'b' so as to form a bight 'c'; pass the end 'a' round behind and under 'b', and through the bight; continue with 'a' to pass it under the standing part 'b', and through the bight 'c' in the opposite direction. This knot forms the best loop that will not slip.

To tie a clove hitch, first pass the end 'a' around a spar, and cross it over 'b'. Pass it around the spar again, and put it through the second bight (Fig. 1). This is a knot that is very useful and safe. For making a line fast to a bollard, the whole process can be quickly done by an expert by merely throwing two loops, placed rightly, over the top of the bollard, and pulling taut (Fig. 2).

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.
