Prof. B. Stewart and W. Dodgson. [Nov. 20, 



14. We have applied the same process to the declination-ranges of 

 the Prague Observatory, selecting the same series of years. From the 

 published records of that institution we have obtained a series of 

 diurnal ranges in which disturbances are included. There are no self- 

 recording instruments at that observatory, bnt observations at 18 h., 

 22 h., 2 h., 10 h., are common to the whole series, and our daily ranges 

 are therefore deduced from these four hours. There is reason to believe 

 that the ranges thus obtained are not greatly different from those 

 which would have been obtained from an hourly series of observations. 



Applying our method to the Prague series, we have obtained the 

 following table (see next page) : — 



15. In applying our method to the results in Tables IX, X, we 

 obtain the following table : — 



Table XI. — Exhibiting the Results of our method applied to Tables 

 IX, X, of our present communication.
