SECTION IX. 
UPON THE GEOGRAPHICAL POSITIONS OP THE FIXED 
POINTS OF THE SURVEY. 
The observations for determining the longitudes of the va- 
rious parts of the coast were taken with a circle and a 
sextant by Troughton: besides these valuable instruments 
we had three chronometers of Arnold’s make, viz., 413 (box), 
2054 (pocket), and 394 (pocket) ; of which the two first 
were supplied by the Admiralty. At the end of the fourth 
year, in consequence of 394 having stopped, a fourth c^o- 
nometer, made by Parkinson and Frodsham (No. 287 box), 
was purchased in the colony, and proved to be a most excel- 
lent watch. 
The situations of the following places, which were either 
fixed by us, or adapted from other authorities, served as 
the basis of the chronometrical determination of the longi- 
tudes of the intermediate parts. 
The flag-staff of FORT MACQUARIE, on the north-east 
head of Sydney Cove in PORT JACKSON, (the Cattle 
Point of Flinders, and otherwise Bennilong Point,) is in 
latitude 33° 51' 28" S., and longitude 151° 15' 26 E., being, 
according to the ensuing table, the mean of all the observa- 
tions that have been taken.
