Deep submarine Diving.
--At attempt to recover the schooner Neptune's Bride, which foundered off Sea Island in November last, was made a few days ago. The exact location of the wreck being discovered, a diver clad in submarine armor went down in twenty-five fathoms, (or one hundred and fifty feet,) of water, but found that the vessel had gone to pieces. This is acknowledged to be the deepest water that the submarine armor has been used in, either in this country or in England. Mr. David Agnew, of Boston, who made the decent, says: ‘"The pressure of air on the head in this depth is five degrees more than on the surface. This is considerably more than I ever experienced on Long wharf, or at any other place, although I must say that, during the two hours and three-quarters that I was down, I felt equally as comfortable as when in ten fathoms." ’
