Page 264 - To God's eternal house direct the way ; A broad and ample road, whose dust is gold, And pavement stars, as stars to thee appear, Seen in the galaxy, that milky way Which nightly, as a circling zone, thou seest Powder'd with stars.
Page 286 - How charming is divine Philosophy ! Not harsh and crabbed, as dull fools suppose, But musical as is Apollo's lute, And a perpetual feast of nectared sweets, Where no crude surfeit reigns.

Page 178 - There is one phenomenon among the fixed stars worthy of mention which, so far as I know, has hitherto been noticed by no one, and indeed cannot be well observed except with large telescopes.
