The table is continued, as above, until 20° to 25° from the 
zenith is reached. It contains the information necessary to apply © 
the foregoing rules for selection. The pains which may be be-  — 
stowed on this table are not lost. Some of the observers prefer, 
in filling it up, to take zones of five degrees at a time, on e 
side of the zenith, and to go through the catalogue thus, several 
times within the limits of the AR determined upon. 
e pairs, then, are selected, and placed according to the ste
