Gheel is a well-worn theme on which it is hard to say anything that is very fresh. But circumstances of various kinds have of late contributed to renew general interest in this ancient settlement. The condition of lunacy affairs in our own country is somewhat fluid just now, and the insertion of any foreign object may help to bring about solidification. Finally, I had occasion to revisit Gheel during the past summer. On the whole, when I was asked for a paper for to-day it seemed not unsuitable that I should fall back upon this time-honoured topic.
