GOULD — REDUCTION OU D AGELET S OBSERVATIONS.

Finally, the computed and adopted values of n, m -f- At, and the clock-rate, for the epoch 

 T, are here presented in tabular form. 



On nine dates, easity recognized from the table of dates and stars, the number of standard 

 stars observed was not sufficiently numerous to afford an adequate determination of m and n, 

 which in these cases were subsequently deduced by employing, in place of standard stars, the 

 mean resultant positions of such others as had been observed by d' Agelet on several occasions. 

 For convenience and to avoid needless complication, the results of these determinations are 

 incorporated in the preceding table, although they were not obtained till after the completion 

 of the remainder of the work. 



The constancy of the deviation n affords gratifying and encouraging evidence of the sta- 

 bility of the quadrant, and of the accuracy of the deduced correction q, large as it is.
