COMPILED CATALOGUE OF LATITUDE STARS. EPOCH 1880. 99 
catalogue, which does not give the second terms of the precession 
or the proper motions, these elements have been taken from the 
former. 
Since the catalogue was commenced for a special purpose, it 
may not be uninteresting to give a short account of the results 
obtained by it, in conjunction with the stars observed at Sydney ; 
premising that the conditions under which the observations at the 
were made were far from satisfactory, as is shown by 
the following extracts from Mr. Conder’s reports ; to which I may 
add that the weather was generally unfavourable. At Sand Hill 
near Barringun, he says :—“ The hill consists of a loose red sand 
y. 
I have mentioned above that only one-third of the original 
programme of B.A.C. stars was used ; and, of the extended list, 
So few had been observed when Mr. Conder started that, had he 
been compelled to depend on them, it would have been necessary 
to telegraph the declinations as they were observed, in order that 
he might be assured that the latitude of each station was known 
within very narrow limi i 
obtained by three settings of the instrument ; the corresponding 
groups consisting of four, five, and seven stars, which under 
These have an extreme range of 349 in the 83 individual 
observations at Station No. 3, which remained after arm 
results had been rejected, and of 2-42 at Station No. 4, in oy 
means deduced from observations of the same pair; whil ae 
average differences of these means from the adopted eee 
the four stations are respectively 0”-25, 0”-62, 0°39 and 0° bi 
of Mr. Conder’s best latitude stations, Mount He 5 at 
Mount Lambie, with the advantage of perfect genie antes
