April , r W 6\ The readings of the Bifilor from 5 1 ' 5"> till 45'" were estimated, as the scale, though in view, was beyond the vertical «i 
Of the telescope : at 175'" the scale was completely out of the field, and the reading given is n rough approximation. 
The half minutes in the times of observations before 6 1 ' 5"' are due to clock error.
