Before leaving Svdney Cove, I placed in the hands of governor 
King two copies of my chart of the south coast of Terra Australis, 
in six sheets ; with three other sheets of particular parts, on a large 
scale. One copy I requested him to send with my letters to the 
secretary of the Admiralty, by the first good opportunity that 
offered ; the other was to remain in his hands until my return, or 
until he should hear of the loss of the Investigator, when it was also 
to be sent to the Admiralty. 
During our stay of twelve weeks at Port Jackson, there were 
not many days favourable to our pursuits at the observatory, the 
weather being dull and rainy for the greater part of the time ; by 
watching all opportunities however, a sufficient number of obser- 
vations were obtained to show the rates of the time keepers, and to 
answer the purposes of geography and navigation 
The Latitude of Cattle Point, from thirty meri- 
dian altitudes in an artificial horizon, of 
which fourteen were taken by Mr. Crosley 
and seven by me in 1795, and nine by lieu- 
tenant Flinders at this time, is - 33 0 5i'45",6S. 
Longitude from forty-four sets of distances 
of the sun and moon, of which the individual 
results are given in Table VI of the Appen- 
dix to this volume, - !£i 11 49 E.* 
•In 1795 and 1796 I took sixty sets of distances upon Cattle Point, an equal 
number on each side, which gave the longitude 151 17' 12" ; but these observations 
not having been calculated with great nicety, nor corrected for the errors of the lunar 
and solar tables, the result is not considered to be of equal authority with that given 
above. The present admiral D'Espinosa, when an officer in the voyage of Malaspina, 
observed an eclipse of the sun at Port Jackson, and occultations of the first 
and second satellites of Jupiter, from which he deduces the longitude ofthetownof
