OBSERVATIONS. 



Equator points of the Mhens-Cirde Continued. 



The quantities here given are the number of seconds to be added to 37 57' in order to obtain 

 the declination corresponding to the zero of the circle. For this purpose all the observations 

 are referred to the thread A ; and besides their mean for each day, as given in the fourth column, 

 a fifth column is added, containing that value which, after some consideration of the weights to 

 be attributed to the different observations and comparison with the results obtained for the pre- 

 ceding and following days, seemed best fitted for conducting to tolerably accordant results. 

 Comparison of the several observations of each night with their mean gives the mean error of 

 a single measurement at Athens of a star's declination, e = 1".444.
