Syme felt almost dazed as he stepped through this growing confusion of lights and shadows; but his companion walked on with a certain briskness, towards where, at the end of the street, an inch or two of the lamplit river looked like a bar of flame.
"Where are you going ?" Syme inquired.
"Just now," answered the Professor, "I am going just round the corner to see whether Dr.Bull has gone to bed.

He is hygienic, and retires early." "Dr.Bull!" exclaimed Syme.

"Does he live round the corner ?" "No," answered his friend.

"As a matter of fact he lives some way off, on the other side of the river, but we can tell from here whether he has gone to bed." Turning the corner as he spoke, and facing the dim river, flecked with flame, he pointed with his stick to the other bank.

On the Surrey side at this point there ran out into the Thames, seeming almost to overhang it, a bulk and cluster of those tall tenements, dotted with lighted windows, and rising like factory chimneys to an almost insane height.
Their special poise and position made one block of buildings especially look like a Tower of Babel with a hundred eyes.
