Page 220 - very high temperatures. Fused silica is now very cheap, but unfortunately the modern furnace methods of production cannot be relied upon to yield a product which possesses the insulating properties of the more expensive silica made by the oxyhydrogen flame. This remark applies alike to the clear transparent variety and the air-streaked satin-like kind. The
Page vii - An atom—who would not let him go. The aether trembled at his agitations In a manner so familiar that I only need to say, In accordance with Clerk Maxwell's six equations It tickled people's optics far away. You can feel the way it's done, You may trace them as they run— dy by dy less
