الصفحة 49 - It may be said of him, what can, perhaps, hardly be said of any other person, that whatever he has done has been perfect at the moment of its production. His processes were all of a finished nature. Executed by the hand of a master, they required no correction; and...
الصفحة 49 - ... perfect at the moment of its production. His processes were all of a finished nature ; executed by the hand of a master, they required no correction ; and though many of them were performed in the very infancy of chemical philosophy, yet their accuracy and their beauty have remained unimpaired amidst the progress of discovery ; and their merits have been illustrated by discussion, and exalted by time.
الصفحة 182 - If from one of the angles of a rectangle a perpendicular be drawn to its diagonal, and from their intersection lines be drawn perpendicular to the sides containing the opposite angle, then putting (P,p) for the last perpendiculars, and (D) for the diagonal, P*+/>* = D*.
الصفحة 20 - If the force vary directly as the distance from the centre, shew that the velocity of a falling body, is to that in a circle at the same distance, as the right sine to the cosine of a circular arc, whose radius is the greatest distance, and versed sine the space through which the body has fallen.

الصفحة 57 - The sum of all the angles of a polygon is equal to twice as many right angles as the polygon has sides, less two.
الصفحة 62 - ... an angle with the tangent equal to that made by the tangent with the axis. Cor. 3. Now as V bisects TD and VB is, parallel to PD, the point .B bisects' TP. Draw FB, and that line bisects the base of an isosceles triangle, it is therefore perpendicular to the base. Hence, we have this general truth : If from the focus of a parabola a perpendicular be drawn to any tangent to the curve, it will meet the tangent on the axis of Y. Also, from the two similar right-angled triangles, FB V and FB T, we...
الصفحة 84 - The earth acts on anybody with a gravitational force inversely proportional to the square of the distance of the body from the centre of the earth.
الصفحة 43 - Since there are 60 seconds in a minute and 60 minutes in an hour, the value of both columns is 60*.
