 April Sd o''. The readings of the Bifilar from ^'^ 5™ till 45"» were estimated, as the scale, though in view, was beyond the vertical wirf 

 of the telescope ; at 17^"" the scale was completely out of the field, and the reading given is a rough approximation. 

 The half minutes in the times of observations before G'' S-" are due to clock error.
