sible, were deduced from Mr. Mosman’s observations; when

The transit observations are given in full, with their reduc- 
Hons for the groups immediately preceding and following the 
longitude-signals, and with the normal equations and resultant 
values for each group. 
A glance at these observations reveals at once, in the small 
residuals, both the accuracy of the star-places and the skill of
