Observed when 1* 40' east of the meridian; the angles are perhaps as good as 

 can be expected at so great a distance from the meridian : the distances, on account 

 of unsteadiness of the stars, were gotten with considerable difficulty, and probably 

 are a little liable to suspicion.

The first set obtained with 181 ; the second set with 413 ; the night unfavour- 

 able ; the stars neither well defined nor steady ; indeed the weather is become very 

 bad for delicate observations.

Stars extremely ill defined and very unsteady ; so much so that I do not consider 

 the results entitled to the least confidence ; measures of distance altogether imprac- 

 ticable ; the night is beautifully clear, not a cloud visible ; but the extreme unstea- 

 diness of the stars obliges me to discontinue observing, although I do it with the 

 greatest reluctance.
