At the beginning of each chapter is a short summary of that chapter. For example, from Chapter 1:
[The author gives some account of himself and family. His first inducements to travel. He is shipwrecked, and swims for his life. Gets safe on shore in the country of Lilliput; is made a prisoner, and carried up the country.]
Were these summaries included in the original publication or added later? Were they written by Swift in the voice of Gulliver's friend, Richard Sympson, or someone else? What purpose are the summaries supposed to serve?
