The English author, Richard Savage, was once living in London in great poverty. In order t

o earn a little money he had written the story of his life, but not many copies of the bock had been sold in the shop, and Savage was living from hand to mouth. As a result of his lack of food he became very ill, but after a time, because of the skill of the doctor who had looked after him, he got well again. After a week or two the doctor sent a bill to Savage for his visits, but poor Savage hadn't any money and couldn't pay it. The doctor waited for another month and sent the bill again. But still no money came. After several weeks he sent it to him again asking for his money. In the end he came to Savage's house and asked him for payment, saying to Savage, "You know you owe your life to me and I expected some gratitude from yon."

"I agree," said Savage, "that I owe my life to you, and to prove to you that I am not ungrateful for your work I will give my life to you." With these words he handed to him two copies entitled THE LIFE OF RICHARD SAVAGE.
