An extraordinary depression of the barometer (height 

 28*612) for that latitude occurred about the same time at 

 Parisf as that in England ; it however occurred at 6 a.m. of 

 the day previous to that in this country, for which reason I 

 have noticed it here, as at first sight it might seem opposed 

 to the general order of the phaenomena presented by the fore- 

 going observations; but it did not occur during "the hurri- 

 cane," for the wind in the Paris meteorological register for 

 the 12th is quoted merely " strong," but on the following day, 

 when the fall corresponding to the great depression in En- 

 gland took place, the wind is quoted " very strong," and the 

 tables show also a fall of the barometer in England on the 12th 

 corresponding with that at Paris. 



I may now conclude this part of the subject by remarking 

 that observations for other periods than those chosen might 

 exhibit difficulties which do not appear in these, although I 

 have made no selection in publishing them, but merely given 

 those I collected on account of the period included in them 



* Time of minimum not noted but during the night of 12-13.
