Results of deep Dredging off the Mull of Galloway. By Capt. Beechey, 

 R.N. Drawn up by Wm. Thompson, V. P. N. H. Soc. of Belfast. 

 Captain Beechey, the distinguished navigator, having in the month of April last 

 been engaged in a survey of part of the Scottish coast in H.M. steam-vessel Lucifer, 

 most kindly undertook to use the dredge in the deepest water in which his soundings 

 might be made, and the following are the highly interesting results obtained on three 

 occasions ; the products from the different depths being most carefully kept separate. 



* PI. myriophyllum was dredged up near the same locality in June 1842. 



t These two species (hitherto unnoticed as British) and other minute ones have been de- 

 termined by Mr. W. Thompson. 



X A remarkable dyke, beginning about 5 miles S.W. the Mull of Galloway, and extending 

 northward nearly to Corsewall. It is from a mile to a mile and a quarter wide. Its average 

 depth in the centre is 1 30 fathoms.
