1844.] Tenth Memoir on the Law of Storms in India. 93 



Brig Dora, report by Capt. Harvey, Commanding her, to Capt. 



BlDEN. 



On Sunday night I experienced a hard gale about N. West, attend- 

 ed with constant rain, hove to with head to the Northward. Monday, at 

 4 p. m. sudden change of wind from the S. West and more moderate ; 

 at noon latitude by observation 12° 50' longitude 82° 25' E. Tuesday 

 exchanged colours with the ship Henry, latitude 12° 56'. Wednesday 

 10 p. m. made Madras Light bearing S. West, but owing to the 

 night's looking so dirty I stood off, and have been in latitude 14° 5', 

 found the current setting strong to the N. Eastward ; during the whole 

 I have not lost or strained a rope yarn. Yours respectfully, 



May 30th. Wm. Harvey.

Barque Coaxer, Capt Ridley. 

 The heaviest of the gale commenced about midnight on Sunday, when 

 we hove to under bare poles. 4 p. m. on Monday the gale moderated ; 

 when we made sail gradually ; our Barometer was as low as 29. during 

 the heaviest of the gale ; we were as far to the Eastward, as 82°26' by 

 Chronometer.

20th May. — Begins with light winds from S. S. W. and ends with 

 strong gales from W. N. W. Barometer at 29.305 and falling. 



2\st May. — Strong gales, heavy rain and thunder and lightning, wind 

 N. W. to W. N. W. throughout, but " strong swell setting in from the 

 Eastward"* is noted in the log at 2 p. m. ; when heavy gales which 

 continued to midnight, Barometer 29.4. 



* These and the other italics are mine. The " strong swell from the Eastward set- 

 ting in on the Coast with a gale blowing directly offshore, is a remarkable phenome- 

 non, which can only I think be explained by the progressive motion of the Storm "Wave.
