"In 1885, Parsons took out his first turbine patent on a motor along the lines previously suggested by Wilson, and is responsible for the successful development of this type of motor. His first turbine, took steam in the center A, and exhausted at both ends through the exhaust passage E E, thus avoiding any end—thrust on the shaft B." —Derr, 1911

Striped, or striated, muscle which quickly contracts causing the alternating black and white lines. It has very delicate fibers (M FL). It is stimulated by nerve fibers (N F), which divide into an endplate (N E) on the contracting surface. N are nuclei, which are a part of elongated cells that fused together to make the muscle. M stands for muscle and N, except for nuclei, stands for nerve.

In making sheet glass, a very large lump of molten glass is gathered on the rod as is shown at (a). This mass is rolled on an iron slab, expanded (b) by blowing down the pipe, and further manipulated by rolling on the slab, reheating at the mouth of the furnace, re-blowing, and allowing the soft mass to hang downward. if the glass is to be used for windows, the blower has a cave in the floor about 8 ft deep, and in this hole he works the glass until he has a cylinder (c), which he swings backward and forward, holding onto the pipe. The cylinder is then blown to a length from 4 to 8 ft, according to the size of the window desired. It becomes very thin and chills rapidly. The blower then takes a second lump of hot glass, pulls it out to a string, winds it around each end of the cylinder (d), and cracks both ends off. A piece of wet iron is next drawn along the cylinder in the direction of the its length, as indicated by the dotted lines in (d). A crack follows the wet iron, and the detached cylinder opens a little at the long crack (e). A slight reheating, and opening out in a flattening kiln, serves to convert the split cylinder into a sheet.

A scriber block is used to layout lines at a set height from the base, thus its second name surface height gauge or just "surface gauge". The work piece is held against an angle plate so that it is perpendicular to the surface plate, the scriber block is then adjusted to the required height and used to scribe a line parallel with the table, by sliding the block along the table's surface.
