ASTRONOMICAL OBSERVATIONS 



For the following observations on Dec. 8, Dec. 9, and Dec. 12, the azimuth error 

 has been assumed zero, as it nearly results from the mean found on December 

 13, 14, and 15; the level error is — 2.8, as found on the 13th and the two follow- 

 ing days. The difference in the values of A on Dec. 8, 9, and 12, is in maximo 

 but 0.1.

 Giving the result by y Pegasi tbe weight two, the observed AR of the moon results as above; it 

 is, however, preferable to reject the result altogether, on account of the great difference in the results 

 Ijy the two stars.
