Mary had been instructed to show him straight in, and, when he was at length announced, the Professor rose at once to greet him. Mr. Ludgrove, seen for the first time, was certainly an imposing and dignified figure. His snowy white hair and beard gave him a patriarchal appearance, produced an almost severe impression, which was only modified by the kindly smile which habitually hovered at the corner of his mouth. His eyes were screened by his powerful spectacles, but one guessed them to be direct and piercing in their expression.

“I am delighted to meet you, Mr. Ludgrove,” said the Professor warmly. “Yes, I am Dr. Priestley, and this is my secretary, Mr. Merefield. I received your letter, and am much obliged to you for your suggestion, which I shall be very glad to fall in with.”
