Page 19 - I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.
Page 13 - Strips of drawing paper in horse-shoe form are placed in a mould and baked at a very high temperature. The charred residuum is then attached to the platinum wires and hermetically sealed in a glass globe from which the air has been exhausted. This attached to a wooden stand, or ordinary gas fixtures, is the whole lamp.

Page 117 - Frequent and prolonged over-charging, with currents about 30 per cent. below maximum, is the only way to reduce badly sulphated plates, which are frequently found when the cells are allowed to run too low or to stand too long. When the positive plates are in a bad condition (generally due to the battery having been over-worked, ie, greatly exhausted, or owing to short circuits within the cell itself, which evidently produces a similar result, or to leakage), it is no easy matter to get them right...
