Among the guests expected at Mr. Drummond's table on that memorable occasion was a gentleman of great note in the scientific world, to whom Mr. Armstrong had been very anxious to be introduced. Indeed, this wish had influenced him greatly in his ready acceptance of the invitation.
"My friend Professor Logan will dine with us on that evening," had been Mr. Drummond's remark to Mr. Armstrong. "I suppose you have read his address at the Royal Society on the inventions of the last thirty years? It was correctly reported in the Times."
"Yes, indeed, and there I saw it," was the eager reply. "Is Professor Logan your friend, Drummond? It will be a great privilege to meet such a man."
"And he will be equally pleased with you," was the reply; "indeed, I expect it will be quite a learned gathering, for I have asked three or four other men of education to join us, and I almost fear the evening will be dull for Mrs. Armstrong and your bright, lively daughter; but Mrs. Drummond will be terribly disappointed if they do not come, and she will make the evening as pleasant as possible for them. My nieces are very musical, and——"
"Oh, pray do not make the invitation more attractive than it is already," interrupted Mr. Armstrong. "My daughter's tastes resemble my own, and she has had advantages of education which I have not. I'm afraid, Drummond, your friends will expect too much from a self-taught man like myself if you have, as you say, placed me on the list of your 'learned' acquaintance."
"Nonsense, Armstrong!" was the reply, as the omnibus stopped for that gentleman to alight. "Mind," he added, as he waved his hand in farewell, "we shall expect you all on Tuesday."
Mr. Armstrong's close carriage arrived at Argyle Lodge only five minutes before the hour appointed for dinner. In a very short time, therefore, Mary found herself being conducted to the dinner-table by a gentleman whose face seemed familiar to her, but whose name, when spoken by her hostess, she had not caught.
"I think I have had the pleasure of meeting Miss Armstrong once before, when she brought her little brother to school," was the remark which made Mary turn and look at her companion.
There was a smile on the face she had called plain, but it did not now deserve such an epithet. The rough, dark hair, which in its disorder she had likened to a "pussy-cat's tail in a rage," was now arranged in shining wavy curls across the broad forehead; the dark eyebrows almost meeting over the nose gave character to the face, and a look in the deep blue eyes, although Mary Armstrong had quickly recognised her companion as Henry Halford, made her ask herself if she had really ever seen them before. So changed was the face, so expressive the glance, so winning the smile, that Mary could only stammer out with a blushing face—
"I beg your pardon, Mr. Halford; I did not at first recognise you, but I do now."
