computed parallaxes of the individual stars, however, serves as impor- 
tant evidence bearing on the validity of the method. 
In Tables I and II are collected all of the stars with measured paral- 
laxes equal to or exceeding +0f05 for which we have spectral observa- 
tions. Table I contains the stars used in the derivation of the curves, 
but in Table II the values are entirely independent, none of these stars 
having been used previously. This table, accordingly, serves as a most 
exacting test of the value of this means of computing parallaxes.
