"Well," said the Professor, as he lifted me up, and looked at me kindly with his large, calm eyes, "I have come a long way to make that discovery; and I wish it were so in Great Russell Street." He was thinking of his labours, and forgetting a far more important matter in our eyes--the two half-holidays procured for us, when he thought that we seemed to require them. For now his vast knowledge, and accuracy, simplicity, gentleness, and playful humour, had won the warm friendship of our Dr. Rumbelow, who seldom caned any of us now, except for lying. For my part, I loved this kind gentleman, and grieved that he had not once asked me to fly for him. "My friend, you are often in my thoughts," he said, as if he knew all that was passing in my mind; "let us sit down a while in this quiet corner, and consider a highly scientific case, which happens to be in my pocket." Smiling at the fright his words had caused, he drew forth a pretty little globular box, yellow, pellucid, and inlaid with stars of gold; and this he held so that the light of the sun glanced through it, illuminating things inside, that danced with colour, purple, and orange, and rosy red. I pulled out my handkerchief, and dried my eyes, and pushed back my curls, for a hearty good stare. "Tommy, your mind is of a wholesome type," said the great Professor pleasantly; "brief should be the pangs of youthful woe. And they are all good to eat, Tommy; and as you suck them, you can pull them out of your mouth, and see the sun shine through, and then put them back, and find them ever so much sweeter." "Oh, but I can't get at them, sir! What good can they be, if I can't get at them?" "Your reasoning is wonderfully sound and good, from its own point of view," he answered. "But get at them, Tommy, and they shall be yours; you shall have box and all, if you open it." This was very hard upon me; for I had no more chance of opening it, than of flying in the air, as people say, and indeed, according to my gifts, much less. In vain I pulled, and squeezed, and pressed, examined every part of it, and then worked away again, screwing up my lips, and eyes, so sternly that the Professor could not help laughing. And the worst of it was, that the more I laboured, the greater the temptation of the inside grew, everything dancing with a play of colours glorious to see, and feel that all was good to eat. "Oh, sir, I can't, I can't get at them; do please to show me the way, sir," I cried; for truly it was enough to make me cry.
