With the common observing power of 1 8 1 the stars were not visible : the observa- 

 tions made on the meridian with 157. Night foggy. 

 October 22nd. The discordance between the two sets of distances is too consi- 

 derable ; between^the 1 6th and this day however, the star has not been visible. The 

 instruments are now dismounted.
