"You cannot bet on friends. They will go and do all sorts of things to spite you. I insured a friend's life once, and got him to assign me the policy. He was a chronic case of rheumatism, and might have died in the course of nature calmly in his bed at any time. We quarrelled one day, and the fellow deliberately sent out and bought a bottle of Connel's East Indian remedies, and took a pint of it every half hour, according to the directions on the label. At the tenth pint he gently dissolved, and the jury brought it in 'determined suicide'. I tried hard to put in a plea of insanity, but it was no use.After this I forswore friendship, except as a gentle stimulant, and in case of sickness."
