1851.] A Twentieth Memoir on the Law of Storms. 17 



altitude was varied by that bright scarlet tinge seen Westward at sunset. This 

 continued from sunset until nearly 9 p. m. During that night much lightning 

 to the Southward and S. Eastward. Also on the 25th, p. m. as per log much 

 heavy thunder and lightning, but none was observed after the gale set in heavy. 



Many Boobies and other sea birds, King Fishers and Dragon Flies, were about 

 the ship on the evening of the 25th. Did not experience any remarkable swell 

 previous to the setting in of the breeze. 



By a diagram which I made the day after, I consider the storm progressing 

 to N. W. b. W. or perhaps more Westerly, about 1\ knots per hour.

25th April. — At 2 a. m. sea rising very suddenly to a fearful height ; too much 

 sea to heave to ; sails, both set and furled, blown from the yards, though the last 

 were well secured. A kind of hard sleet almost cutting the skin. Wind 

 unsteady with heavy gusts ending at S. East. Barometer at 2 a. m. 29.40 ; 

 from which time it could no longer be seen in the ship's distress. At 2.30 a. m. 

 two of the between deck ports were stove in and the vessel was nearly swamped 

 with the quantity of water on her main deck. Ship on her beam ends and 

 cabins boats and everything moveable washed away ; ship settling down, cut away 

 the main and foremasts, all hands baling and pumping and clearing wreck. Noon, 

 weather still very heavy, wind South East decreasing with less sea to midnight. 



* la the distress and swamping arising from the ship's between deck ports having 

 been beaten in, her log-book was destroyed.
