Stars remarkably steady ; the small one is decidedly light blue, and bears only 

 a feeble illumination ; hence the measures are difficult.

The observations of June 29th are not included ; as how- 

 ever the measures are of very considerable difficulty, I have 

 not thought it advisable to suppress them.
