dancing motion. I thought at first my eyes deceived me, but my

Capt. R.— remarks. " I find Bar. considerably fallen with an exceed- 

 ing long swell from the Southward, and at 7 a high N. N. W. sea 

 meeting the Southerly swell created an exceedingly turbulent sea. 

 In the squalls the sea has a strange appearance, the two seas dashing 

 their crests against each other shoot up to a surprising height and 

 being caught by the West wind, it is driven in dense foam as high as 

 our tops. The whole horizon has the appearance of ponderous breakers. 



At 8, Bar. still falling; has there been a gale? Much electricity 

 by the appearance of the clouds. Current 59 miles N. E. b. E. \ E. 

 this 24h. p. m. breeze decreasing to 1J knots, winds West to South and 

 at times calm. Clouds, strata and nimbi, making preparations for bad 

 weather, appearances being suspicious, 11. 30 p. m. Lat. by Aldebaran
