"I am not a common Frölich to-day," replied the fool gravely. "It has pleased His Majesty to appoint me as his chamberlain for four-and-twenty hours, and in fulfilment of my duties I am come to announce to you that Diana, accompanied by Apollo, will honour Herr Bottiger with a visit. Dixi!"

He rapped with his stick. All the guests sprang to their feet. Bottiger and Nehmitz began to clear the table. The window was thrown open, and a servant despatched for fresh flowers. The guests disappeared by the side balconies, for they knew that the king would come by way of the back balcony. The alchemist, Fürstenburg, and Nehmitz alone remained to greet them.

The furniture was hastily placed in proper order, the floor was strewn with flowers, and Bottiger stood on the threshold with a bouquet.

Soon the room was brightened by the arrival of Cosel in the full splendour of her beauty. The prisoner knelt.

"We always receive a goddess kneeling," said he, "and the best sacrifice we can offer her is scented flowers."

Cosel smilingly accepted the flowers her host offered, and then looked around inquisitively, wondering that there was not the least indication of the great work that was in progress.

The King followed her, and explained that they were not in the laboratory.

"But I should like to see that mysterious sanctuary," said she.

"Madam," replied Bottiger, "it is such a fearful den, the air is so unhealthy, and the aspect so sad, that a goddess should not descend into such a hell."

"But woman's curiosity!" sighed Cosel, and looked at Augustus. The King looked at Fürstenberg; but the Prince only shrugged his shoulders.
