Side 3 - A circle is a plane figure contained by one line, which is called the circumference, and is such that all straight lines drawn from a certain point within the figure to the circumference, are equal to one another.
Side 2 - When a straight line standing on another straight line makes the adjacent angles equal to one another, each of the angles is called a Right Angle; and the straight line which stands on the other is called a Perpendicular to it.
Side 80 - The projection of a point upon a plane is the foot of the perpendicular from the point to the plane.
Side 2 - When several angles are at one point B, any one of them is expressed by three letters, of which the letter that is at...
Side 121 - The strength of a pillar, with one end round and the other flat, is the arithmetical mean between that of a pillar of the same dimensions with both ends round, and one with both ends flat. Thus, of three...
Side 33 - This done, press the protractor gently down, which will fix it in position by means of very fine points on the under side. It is now ready to lay off the given angle, or any number of angles that may be required, which is done by turning the pinion d till the opposite vernier reads the required angle. Then press downwards the branches...
Side 117 - VIII, leads to the following remarkable conclusion, easily fixing itself in the memory, that with the unguents, hogs* lard and olive oil interposed in a continuous stratum between them, surfaces of wood on metal, wood on wood, metal on wood, and metal on metal, when in motion, have all of them very nearly the same co-efficient of friction, the value of that co-efficient being in all cases included between 0,07 and 0,08, and the limiting angle of resistance therefore between 4° and 4° 35'.
Side 384 - Having poured a little of the solution into a flat dish, the pictures are to be introduced into it one by one; daylight will not now injure them ; let them soak for two or three minutes, or even longer if strongly printed, turning and moving them occasionally. The remaining unreduced salts of silver are thus thoroughly dissolved, and may now, with...
Side 20 - ... or 2-53, according as the primary divisions are taken as hundreds, tens, or units. General Rule. — To take off any number to three places of figures upon this vernier scale. Increase the first figure by one; subtract the third figure from the second, borrowing one- from- the first increased figure, if necessary, and extend the compasses from the division upon the vernier -scale, indicated by the third figure, to the subdivision indicated by the number remaining after performing the above subtraction.
Side 38 - MOUNTING PAPER AND DRAWINGS, VARNISHING, ETC. In mounting paper upon canvas, the latter should be well stretched upon a smooth flat surface, being damped for that purpose, and its edges glued down as was recommended in stretching drawing paper. Then with a brush spread strong paste upon the canvas, beating it in till the grain of the canvas be all filled up; for this, when dry, will prevent the canvas from shrinking when subsequently removed ; and, having cut the edges of the paper straight, paste...
