north. A good many pieces of sea-weed were seen floating; 

 this evening, resembling in colour and figure the common 

 spray. They generally make their appearance, and in great 

 quantities, a little farther to the north. They are supposed 

 to be brought from the American coast by the current, which 

 may be considered a branch of the Gulf Stream. Not only 

 these weeds, but the state of the thermometer, seem to indi- 

 cate that we have been in a current to-day. The night was 

 very fine, and the breeze moderate. We saw the southern 

 coast a little above the horizon.

During the twenty-four hours before noon, we have been 

 carried thirty-two miles to the west, and ten to the northward. 

 A little sea-weed was seen yesterday, and a good deal this morn- 

 ing. It is a delicate species of fucus. The stem and branches 

 were cylindrical, and the leaves long and lanceolated, and 

 there were attached to the brandies numerous hollow spheri- 

 cal bodies. The colour of the weed was between light apple- 

 green and straw-yellow. Many of the spherical bodies were 

 enveloped in a delicate crust, or a reticulated coral loid, quite 

 white. Several small eels, of the same species, were caught 

 o» the weed, and two or three gelatinous bodies, of regular 

 forms, and irritable.
