They were staying at the "Rose Inn," at Guild, this learned gentleman and his wife. Professor Macpherson (as he was frequently called) had come down on some mission connected with geology. He was a very wire of a man, tall and thin as a lamp-post, exceedingly near-sighted, even in his silver-rimmed spectacles that he constantly wore; a meek, gentle, simple-minded man, whose coats and hats were threadbare, a very child in the ways of the world; as these excessively abstruse spirits are apt to be. Mrs. Macpherson was in all respects his opposite: stout in figure, fine in dress, loud in speech; and keen in the affairs of common life. Good-hearted enough at the main, but sadly wanting in refinement, Mrs. Macpherson rarely pleased at first; in short, not to mince the matter, she was undeniably vulgar. Mrs. Macpherson's education had not been equal to her merits; her early associations were not of the silver-fork school. She was a very pretty girl when Caleb Macpherson (not the great man he was now) married her; habit reconciles us to most things, and he had discovered no fault in her yet. That she made him a good wife was certain, and a very capable one. This was the second visit Professor Macpherson had made to Guild. The first took place about half a dozen years ago, when he had come on a question of "pneumatics." He had then become acquainted with the Reverend Mr. Chester, not himself unlearned in science, and had spent several hours of three separate days at the rectory. James Chester had gone now where science probably avails not; Mrs. Chester had quitted the rectory; and it might have chanced that the acquaintanceship would never have been renewed but for an accidental meeting. Mrs. Chester was walking quickly into Guild on an errand when she met him. He would have passed her; her style of dress was altered--and for the matter of that he always went (as his wife put it) mooning on, his head in the skies and looking at nobody. But Mrs. Chester stopped him. Except that he looked taller and thinner, and his coat a little more threadbare than of old, and his spectacles staring out straighter up at the clouds or at the far-off horizon, he was not altered. "Have you forgotten me, Dr. Macpherson?" It took the doctor some few minutes to bring himself and his thoughts down to the level of passing life. Mrs. Chester had to tell him who she was, and that she was now alone in the world. He took both her hands in his then, and spoke a few words of genuine sympathy, with the sorrowful look in his kind eyes, and the tone of true pity coming from his ever-open heart. "You will come and call on me, will you not?" she asked, after telling him where she lived. "I'll come this evening," he said, "and bring my wife. She's with me this time."
