Read it through once

Now, the Captain D’Wolf here alluded to as commanding the ship in question, is a New Englander, who, after a long life of unusual adventures as a sea-captain, this day resides in the village of Dorchester near Boston. I have the honor of being a nephew of his. I have particularly questioned him concerning this passage in Langsdorff. He substantiates every word. The ship, however, was by no means a large one: a Russian craft built on the Siberian coast, and purchased by my uncle after bartering away the vessel in which he sailed from home.
