Is not a Patron, my lord, one who looks with unconcern ona manstruggling for life inthewater, and,whenhehas reached ground, encumbers him with help? The notice which you have been pleased to take of my labours, had it been early, had been kind; but it has been delayed till I am indifferent, and cannot enjoy it; till I am solitary, and cannot impart it; till I am known, and do not want it.
