How does walton describe the stranger?

"His limbs were nearly frozen, and his body dreadfully emaciated by fatigue and suffering. I never saw a man in so wretched a condition. We attempted to carry him into the cabin; but as soon as he had quitted the fresh air, he fainted. We accordingly brought him back to the deck, and restored him to animation by rubbing him with brandy, and forcing him to swallow a small quantity. As soon as he showed signs of life we wrapped him up in blankets, and placed him near the chimney of the kitchen stove. By slow degrees he recovered, and ate a little soup, which restored him wonderfully."
