this memoir the results of his observations on double stars with 
the sae inch equatorial of the Naval Observatory, made 
during the five years, 1875-9, together with a few measures made 
in 1863, with the 9.6 equatorial. 
A group of observations is first given on selected stars, made 
in concert wit r. Struve and Baron Dembowski, for the e pur- 
pose of eliminating constant errors of ponies angle ‘if possible. 
A series of measures upon two triple stars and upon the trape- 
zium of Orion, give further means of estimating the accuracy of 
Professor Hall’s measures with the great equatorial. The main 
part of the memoir is devoted to the measures of other double 
stars. The total number of observations is 1,614 on over 400 
different stars. When we consider that one good observation of 
a dou ea star is ‘orth scores of those of moderate or doubtful 
value, appreciate more highly the value of such a series of 
bbaseratione i such an observer. Bsa.
