$A longcase clock, also tall-case clock, floor clock, or grandfather clock, is a tall, freestanding, weight-driven pendulum clock with the pendulum held inside the tower, or waist of the case. The English clockmaker William Clement is credited with the development of this form in 1670. Most longcase clocks are striking clocks, which means they sound the time on each hour or fraction of an hour.$

A tracked vehicle is a vehicle that runs on continuous tracks instead of wheels. The principal design advantages of tracked over wheeled vehicles are that they are in contact with a larger surface area than would generally be the case with a wheeled vehicle, and as a result exert a much lower force per unit area on the ground being traversed than a conventional wheeled vehicle of the same weight.

"When an Egyptian died the friends of the deceased went at once to the embalmer, By him they were shown a set of models, that is, wooden images painted and wrapped in imitation of the different styles of mummies prepared at the establishment. The models were divided into three classes; first, second, and third; and among these the friends selected according to their rank and means. The dead body was then delivered to the embalmers, by whom the brain was removed through the nostrils. Then an incision was made in the left side with a sharp stone. Through this opening the entire viscera were removed, and being cleansed by washing with palm wine, were covered with pounded aromatics and deposited in four urns. The cavity of the body was filled with powdered myrrh, cassia, and other fragrant substances, and the wound carefully sewn up. The whole body was then packed for seventy days in salt and carbonate of soda, at the end of which time it was washed and then wrapped in linen bands anointed on the inner surface with a certain gum which acted as glue. The mummy was finally put into a wooden case in the form of a man, and delivered to the relatives, by whom it was set upright against the wall in one of the rooms of their house."—Ridpath 1885

Striation of crystal planes may be produced by repeated polysynthetic twinning. This is well illustrated in the case of the triclinic feldspar, Albite. The twinning plane here is the brachypinacoid, and the contact of a large number of fine lamellæ, alternately in twinning position, would evidently produce a striation on the basal plane parallel to the brachydiagonal axis

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.
