360 Eighth Memoir on the [No. 137- 



Reports from Pondicherry. 



24th October. — The day the gale took place, the Barometer which 

 had fallen on the previous day, rose at 8 o'clock to 28 inches and 2 lines. 

 F (or 30.05 Eng.) At J past 9 o'clock, it began again to fall gradually 

 until noon, when it was at 28 inches, lines, and 8 points (or 29.90 

 Eng). It continued to fall, and at 2 o'clock, at which hour a signal 

 was made for vessels to get ready to put to sea, the Barometer was at 

 27 inches and 10 lines; (29.80 E) still falling, at 3 o'clock the wind 

 was very strong, the sudden gusts becoming very fierce ; the Barome- 

 ter having somewhat further fallen. At a J before 4 o'clock, the gale 

 was blowing from N. E. to W. until 20 minutes past 5 o'clock. The 

 Barometer was then at 27 inches and 2 lines, (29.15 ) when suddenly 

 the wind became lulled until 6 o'clock, but afterwards it blew fresh 

 from the S. W. During the calm, the Barometer fell below storm, but 

 rose again in the evening. 



Second Report. 



24th October. — The Barometer had fallen to 26 inches and 10 lines, 

 (28.65 E) two lines below storm, and remained thus from 20 minutes 

 past 5 o'clock until 6, when the wind began again to blow strong 

 from the S. W. 



On the 2d instant, the Barometer was at 28 inches and 3 lines 

 (30.1 E). 



During the gale, the Barometer fell half an inch below what it did 

 in the gale of 1830, and was stronger than any I remember in these 

 parts. 



It is to be remarked, that from 2 to 5 o'clock in the afternoon, at 

 the most violent part of the storm, the oscillations of the mercury* 

 in the Barometer were so apparent, that it rose and fell instantane- 

 ously 2 to 3 lines, as though somebody had shaken the Barometer. 



It appears from the reports received, that the storm reached to the 

 W. to the distance of 75 miles, consequently from 70 to 80 leagues 

 from W. to E., for Captain Thevenard was not at the limit of the 

 storm when he felt it, at 40 leagues to the East. 



From S. to N. the storm does not appear to have made so large a 

 zone, as it was not felt further than Porto Novo.t 



* Italics are mine. 



f This is an error, as it was distinctly felt at Nagore, a degree farther South.— H. P-
