In the great majority of cases these results pronounce emphati- 

 cally against the supposition of a parallax large enough to be detected 

 amid the errors of observation which are inseparable from the method 

 which has been adopted. In no case do they afford reliable indica- 

 tions of a parallax large enough to be detected by the method of' 

 reconnoitring.
