Lord Howe Island its zoology, geology, and physical characters. No. 5. The physical and geological structure of Lord Howe Island
Abstract
[Excerpt from Introduction]. The geographical position of Lord Howe Island has been already described, and it has been shown that under this name are included a number of outlying rocks. Chief amongst these are the Admiralty Islets to the north; Mutton Bird Island to the east; Rabbit or Goat Island, within the Lagoon, on the west; and the solitary pinnacle, Ball's Pyramid, away to the southeast.
