Variant: He thought he saw a Banker's Clerk
Descending from the bus:
He looked again, and found it was
A Hippopotamus:
'If this should stay to dine,' he said,
'There won't be much for us!

“"Our Second Experiment", the Professor announced, as Bruno returned to his place, still thoughtfully rubbing his elbows, "is the production of that seldom-seen-but-greatly-to-be-admired phenomenon, Black Light! You have seen White Light, Red Light, Green Light, and so on: but never, till this wonderful day, have any eyes but mine seen Black Light! This box", carefully lifting it upon the table, and covering it with a heap of blankets, "is quite full of it. The way I made it was this - I took a lighted candle into a dark cupboard and shut the door. Of course the cupboard was then full of Yellow Light. Then I took a bottle of Black ink, and poured it over the candle: and, to my delight, every atom of the Yellow Light turned Black! That was indeed the proudest moment of my life! Then I filled a box with it. And now - would anyone like to get under the blankets and see it?"Dead silence followed this appeal: but at last Bruno said "I'll get under, if it won't jingle my elbows."Satisfied on this point, Bruno crawled under the blankets, and, after a minute or two, crawled out again, very hot and dusty, and with his hair in the wildest confusion."What did you see in the box?" Sylvie eagerly enquired."I saw nuffin!" Bruno sadly replied. "It were too dark!""He has described the appearance of the thing exactly!"”

the Professor exclaimed with enthusiasm. "Black Light, and Nothing, look so extremely alike, at first sight, that I don't wonder he failed to distinguish them! We will now proceed to the Third Experiment."</p>

“Be sure the safest rule is that we should not dare to live in any scene in which we dare not die.”

Preface
Sylvie and Bruno (1889)
Context: I believe this thought, of the possibility of death — if calmly realised, and steadily faced would be one of the best possible tests as to our going to any scene of amusement being right or wrong. If the thought of sudden death acquires, for you, a special horror when imagined as happening in a theatre, then be very sure the theatre is harmful for you, however harmless it may be for others; and that you are incurring a deadly peril in going. Be sure the safest rule is that we should not dare to live in any scene in which we dare not die.
But, once realise what the true object is in life — that it is not pleasure, not knowledge, not even fame itself, 'that last infirmity of noble minds' — but that it is the development of character, the rising to a higher, nobler, purer standard, the building-up of the perfect Man — and then, so long as we feel that this is going on, and will (we trust) go on for evermore, death has for us no terror; it is not a shadow, but a light; not an end, but a beginning!

“Fading, with the Night, the memory of a dead love, and the withered leaves of a blighted hope, and the sickly repinings and moody regrets that numb the best energies of the soul: and rising, broadening, rolling upward like a living flood, the manly resolve, and the dauntless will, and the heavenward gaze of faith — the substance of things hoped for, the evidence of things not seen!
"Look Eastward! Aye, look Eastward!"”

“I do not know if 'Alice in Wonderland' was an original story — I was, at least, no conscious imitator in writing it — but I do know that, since it came out, something like a dozen story-books have appeared, on identically the same pattern.”

Context: I do not know if 'Alice in Wonderland' was an original story — I was, at least, no conscious imitator in writing it — but I do know that, since it came out, something like a dozen story-books have appeared, on identically the same pattern. The path I timidly explored believing myself to be 'the first that ever burst into that silent sea' — is now a beaten high-road: all the way-side flowers have long ago been trampled into the dust: and it would be courting disaster for me to attempt that style again.

“Is all our Life, then, but a dream
Seen faintly in the golden gleam
Athwart Time's dark resistless stream?”

Sylvie and Bruno (1889)
Context: p>Is all our Life, then, but a dream
Seen faintly in the golden gleam
Athwart Time's dark resistless stream?Bowed to the earth with bitter woe
Or laughing at some raree-show
We flutter idly to and fro.Man's little Day in haste we spend,
And, from its merry noontide, send
No glance to meet the silent end.</p
