CHAPTER 1
18/34
As these were continued during our outward voyage as far as Van Diemen's Land, and the number of observations amounted to 69, the results will more clearly be understood if exhibited in a tabular form, for which the reader is referred to the Appendix.
"Two of the Sixe's thermometers were attached, one at the bottom of the line of 370 fathoms, the other 150 fathoms higher up.
The depth recorded is that given by Massey's patent sounding machine.
As the same quantity of line was always used, the difference of depth of each day should be trifling, varying only in proportion to the ship's drift; yet on several occasions the depth recorded by the machine gives as much as 100 fathoms short of the quantity of line let out."* (*Footnote.
Lieutenant Dayman, R.N.) BOAT CAPSIZED.
While engaged in sounding, a process which usually occupied three-quarters of an hour, a boat was always at my service when birds were about the ship, and the state of the sea admitted of going after them--by this means many species of petrels were obtained for the collection.
