Rollo felt very much rejoiced at hearing this prescription, though still he looked very sober; for he felt somewhat awed and restrained by being in the doctor's office. There were a good many large books, in cases upon one side of the room; and strange, uncouth-looking pictures hanging up, which, so far as Rollo could see, did not look like any thing at all. Then there was an electric machine upon a stand in one corner, which he was afraid might in some way "shock" him; and some frightful-looking surgical instruments in a little case, which was open upon the table in the middle of the room.
