REPORTS FROM THE SECTIONS. 225 
from one observatory to the ears without fm corse Signals 
were therefore exchanged between the Venerable oe 
Stock, B.A., and myself, with the following result :—F. 
Wellington to Sydney, lh. 34m. 15-35s. ; Sydney to Wellington, 
lh. 34m. 16-648. But it appears that the signals rec 
Wellinaton from Sydney were received by an assistant, aes cry 
as soon as he saw the signal from Sydney, was compared with the 
clock by Archdeacon Stock, and I quite agree with the view of 
Archdeacon Stock—that in such a process time must have been 
ars and it does not appear that any attempt was made to deter- 
how much was so lost; as the signals were received and 
seiewiod on the chronograph at Sydney by one observer, it is more 
than ge ae that the result so obtained is the more correct of 
the two. I therefore adopt, as has been done by Archdeacon 
Palmer’s longitude, we have 10h. 4m. 49-46s. as the resulting 
longitude of Sydney. We thus have four values of the longitude 
of Sydney.

And T have no veto that these differences may all be accounted 
for by personality in observing the moon, and the question is 
naturally asked whieh is right, but it is impossible to say, and 
question must, I fear, eft unanswered until the Cosaesian 
shall have been determined by the use of the alogrens lines. It 
is very much to be regretted that the various transit of Venus’ 
parties did not combine and do this important work when they 
were in the Pacific Ocean. Probably it will « long before such 
« number of trained observers will be again on the spot to do this 
work, and the cost of doing it now would be considerable. 
I have only to say in conclusion that in future the longitude of 
ee Observatory will be assumed to be 10h. 4m. 50°81s
