 We find in the <unk> of both Male and Female , a brown Stone , of the bigness of a Hen 's Egg , ' tis somewhat rough , flat on one side and round on the other , heavy and hard . We believe this Stone was there when they were hatched , for let them be never so young , you meet with it always . They never have but one of ' em , and besides , the Passage from the Craw to the <unk> is so narrow , that a like Mass of half <unk> <unk> 'd not pass . It serv 'd to whet our Knives better than any other Stone Whatsoever .
