The professor did not open his eyes, and appeared to be slumbering on, but very shortly afterwards called out again, “Joseph! Confound the fellow! where is he?” It was evident that he was half dreaming about a former servant now far away on the ancient globe. “Where’s my blackboard, Joseph?”

“Quite safe, sir,” answered Ben Zoof, quickly.

Rosette unclosed his eyes and fixed them full upon the orderly’s face. “Are you Joseph?” he asked.

“At your service, sir,” replied Ben Zoof with imperturbable gravity.

“Then get me my coffee, and be quick about it.”

Ben Zoof left to go into the kitchen, and Servadac approached the professor in order to assist him in rising to a sitting posture.

“Do you recognize your quondam pupil, professor?” he asked.

“Ah, yes, yes; you are Servadac,” replied Rosette. “It is twelve years or more since I saw you; I hope you have improved.”

“Quite a reformed character, sir, I assure you,” said Servadac, smiling.

“Well, that’s as it should be; that’s right,” said the astronomer with fussy importance. “But let me have my coffee,” he added impatiently; “I cannot collect my thoughts without my coffee.”
