All this was in company with the business he was carrying on of applying the splints and bandaging the broken leg; after which, by aid of the doctor’s walking-sticks, he limped to the door, as there was no one to carry him, thanked himself for his kindness, and in imagination departed, leaving himself in the character of the doctor, whose walk he imitated as he drew out a large pill-box, opened it, and took a small pinch of magnesia as if it were snuff.

Another peep at the doctor through the keyhole, and a run to the door, to make sure of there being no interruption there, and then the boy’s face assumed a very serious expression. He took the cloth from the little table in the corner, rolled up the hearthrug longwise, and tied it in two places with string, and then treating it as a patient, he laid it on the settee, and drew over it the table-cover.

He was not satisfied, though, and getting a square of paper, such as would be used to wrap up a bottle of medicine, he poked his finger through twice for eyes, made a slit for a mouth, and puckered the paper for a nose.

This rough mask he tied at the end of the long roll, drew the table-cover up to the face, and then came to see the patient, carried on an imaginary conversation with a colleague, and ended by going to a cupboard and getting out a long mahogany case.

Bob’s reading for the past two years had not been the wholesome and unwholesome literature provided for our youth, but the contents of the doctor’s little library, the Lancet, and the Medical Times. These proceedings were the offspring.

To carry out the next proceedings, Bob took off his jacket and rolled up his sleeves; informed his colleague that it was a bad case—a diseased heart—and the only hope for the patient’s life was to take it out completely.

This Bob proceeded to do with goblin-like delight. He turned the table-cover half down before opening the mahogany case, which contained a set of long amputating knives; and these he tried one after the other, to satisfy himself about the edge before commencing the operation, with great gusto, cutting the string that bound the hearthrug, making an incision, and extracting the heart. Next the place was sewn up, the cover replaced, the knives put away with horrible realism, the patient’s pulse felt and a little stimulus administered—the boy taking this himself—to wit, a little ammonia and water.

Next the table-cover was drawn off, the hearthrug restored to its place; and, grinning now hugely, Bob went to a drawer, and got out the doctor’s tooth-drawing instruments—for the doctor belonged to the old school, and in distant times had not been above removing a decayed and aching molar from a patient’s jaw.

The boy flourished the instruments about with evident enjoyment, going as far as to take a good hold of one of his teeth, but he refrained from pulling, and rubbed his half-numbed hands.

It suddenly seemed to occur to him that he had not put on his jacket, and resuming this, and proving its many buttons to be a sham, for it fastened in a feminine manner by means of a series of hooks and eyes, he made a bound to the settee, grinning with pleasure as he threw it open, dived down, and brought out a glistening white human skull, handling it with a weird kind of delight painted in his face.
