first part of this paper. It is therefore, for the enlightened and pa- 

 triotic inhabitants of Liverpool, to take the initiative in the great and 

 important work proposed. Their interests as well as their philanthropy 

 require that no time should be lost. Let them be up and doing, and 

 may the blessing of God crown their efforts with success. 



Since this Paper was read to the Society, I have undertaken a 

 laborious discussion of my meteorological registers for the years 1840 to 

 1847, inclusive, with the view of testing the correctness of the opinion 

 which I have long held — that the directions of the progressive motions 

 of cyclones are the same as those of the upper currents at the time, as 

 indicated by the motions of cirri. The result is shewn in the following 

 table : — 



• Nine months, April to December, inclusive. + Six months, viz., Jan., Feb., Sept., Oct, Nov., & Dec. 

 Column A contains the number of instances in which the agreement of the 



motions of the cyclones with those of the upper currents at the time 



appeared complete. 

 B cases in which tlie diflference did not exceed one principal point 



(reckoning 16 to the compass card) or 22^°. 

 C cases in which the diflference appeared to exceed the same. 

 D cases in which the directions of the motions of the cirri or of the 



cyclones were doubtful. 

 E cases in which the motions of the cirri were not observable during the 



passage of the cyclones. 



It thus appears that in 58 cases, or nearly two-thirds of these quoted, 

 the agreement is as close as could be expected ; in 31 cases satisfactory 

 grounds of comparison were not attainable ; leaving only one instance 

 out of 90 in which any considerable disagreement was apparent. In con- 

 stnicting this table, all the decided storms which passed over this part of 

 the countiy during the period to which it refers were selected, and the 

 directions of their progressive motions ascertained as nearly as possible, —
