IN EUROPE DURING OCTOBER, NOVEMBER, AND DECEMBER 1863. 



199 



sometime after 8 a.m. of the 10th. Hence, 15 miles per hour may be accepted as 

 the minimum rate per hour travelled by any of these storms. The greatest 

 distance travelled on any day was from the 4th to the 5th, being 700 miles, or 

 29 miles per hour. 



If Storm VI. really overtook Storm V. by the morning of the 12th, its pro- 

 gressive motion must have far exceeded any of those in the table, since it must 

 have travelled, in twenty-four hours, at least 1050 miles, or 46 miles an hour. 

 The following observations, in addition to those given in the table, bear on this 

 interesting point : —

At 12 noon, the pressure at Paris was 2939, and wind S.S.E. ; and at Luxem- 

 burg 29-52, and wind S.W. From these observations, it is probable that this 

 storm continued to advance southwards for an hour or two after the morning 

 observation; it then turned to the N.E., and in the evening advanced over 

 the North Sea nearly to the south of Norway, as shown by the pressure and 

 direction of the winds at that time, and soon after became absorbed in Storm V. 

 As the position of the centres of Storms VIII. and X. could be ascertained only 

 on one day, the rate of their motion cannot be determined.
