"Where does my grandsire dwell?" asked Auriol.

"Why here, sir," replied the dwarf; "and for the matter of locality, the house is situated on the south end of London Bridge."

"On the bridge—did you say on the bridge, friend?" cried Auriol.

"Ay, on the bridge—where else should it be? You would not have your grandsire live under the river?" rejoined the dwarf; "though, for ought I know, some of these vaults may go under it. They are damp enough."

Auriol was lost in reflection, and did not observe a sign that passed between the dwarf and Rougemont.

"Will it disturb Doctor Lamb if his grandson goes up to him?" said the latter, after a brief pause.

"My master does not like to be interrupted in his operations, as you know, sir," replied the dwarf, "and seldom suffers any one, except myself, to enter his laboratory; but I will make so bold as to introduce Master Auriol, if he desires it."

"You will confer the greatest favour on me by doing so," cried Auriol, rising.

"Sit down—sit down!" said Rougemont authoritatively. "You cannot go up till the doctor has been apprised. Remain here, while Flapdragon and I ascertain his wishes." So saying, he quitted the chamber by a farther outlet with the dwarf.

During the short time that Auriol was left alone, he found it vain to attempt to settle his thoughts, or to convince himself that he was not labouring under some strange delusion.
