* [Nore.—The remaining portion of the records, which were evidently 
written under a misconception as to the nature of the rock passed through, 
is omitted. The “dark grey stone without fossils,” which is subsequently 
described as “limestone,” is a fine grainel crystalline diabase passing in 
the ordinary way into a coarser variety noted as “very coarse rock like 
granite.” This rock must have been struck between 509 and 519 feet from 
the surface. |
