Page 111 - that every particle of matter in the universe attracts every other particle, with a force whose direction is that of the line joining the two, and whose magnitude is directly as the product of their masses, and inversely as the square of their distances from each other.
Page 174 - A thrilling, extending from the chest to the extremities, was almost immediately produced. I felt a sense of tangible extension, highly pleasurable, in every limb; my visible impressions were dazzling and apparently magnified; I heard distinctly every sound in the room, and was perfectly aware of my situation.
Page 200 - The sound spoke eloquently to the geologist; the thousands and thousands of stones, which, striking against each other, made the one dull, uniform sound, were all hurrying in one direction.
