3: Men in a circle. (March 1889)

Some men sat in a circle, so that each had 2 neighbours; and each had a certain number of shillings. The first had 1/- more than the second, who had 1/- more than the third, and so on. The first gave 1/- to the second, who gave 2/- to the third, and so on, each giving 1/- more than he received, as long as possible. There were then 2 neighbours, one of whom had 4 times as much as the other. How many men were there? And how much had the poorest man at first?
