The apparent places of the standard stars referred to the equinox 
of 1888.0 were computed according to the method of Sec. VI. Proper 
motions were taken from the following sources: for 8 = Bradley 65 
from Harvard Annals, Vol. XVIII, p. 283; for « = Groom. 1119, and 
pw = Bradley 1672 from Green. Ten Year Catalogue 1890; for g==A 
Ursae Majoris from the Berliner Jahrbuch. ‘The plateconstants were 
determined by a comparison with the apparent places computed 
by equations (1a), quoted above, using approximate values which 
could easily be found. Table IV which follows contains the constants 
for the eight 89° plates, and Table V contains their probable errors.
