Read it through once

Here, it must needs be said, that accidents like this have in more than one case occurred to ships in violent storms. The magnetic energy, as developed in the mariner’s needle, is, as all know, essentially one with the electricity beheld in heaven; hence it is not to be much marvelled at, that such things should be. In instances where the lightning has actually struck the vessel, so as to smite down some of the spars and rigging, the effect upon the needle has at times been still more fatal; all its loadstone virtue being annihilated, so that the before magnetic steel was of no more use than an old wife’s knitting needle. But in either case, the needle never again, of itself, recovers the original virtue thus marred or lost; and if the binnacle compasses be affected, the same fate reaches all the others that may be in the ship; even were the lowermost one inserted into the kelson.
