 oc Polaris S. P. in the Autumn. 



The mean of 42 observations gives mean zenith distance = 

 3&M8'.46",76-[-,84p. A comparison of the mean of the observations 

 in spring and of the mean of these in Autumn gives 4?",21 — ,68p 

 = 46,76 + ,84p. or p = 0'',30 from which also I infer that the 

 parallax of » Polaris (if any) is too small to require to be noticed.
