MRS. ESDAILE, of the Lindens, Birchespool, was a lady of quite remarkable scientific attainments. As honorary secretary of the ladies' branch of the local Eclectic Society, she shone with a never-failing brilliance. It was even whispered that on the occasion of the delivery of Professor Tomlinson's suggestive lecture "On the Perigenesis of the Plastidule" she was the only woman in the room who could follow the lecturer even as far as the end of his title. In the seclusion of the Lindens she supported Darwin, laughed at Mivart, doubted Haeckel, and shook her head at Weissman, with a familiarity which made her the admiration of the University professors and the terror of the few students who ventured to cross her learned but hospitable threshold. Mrs. Esdaile had, of course, detractors. It is the privilege of exceptional merit. There were bitter feminine whispers as to the cramming from encyclopædias and text-books which preceded each learned meeting, and as to the care with which in her own house the conversation was artfully confined to those particular channels with which the hostess was familiar. Tales there were, too, of brilliant speeches written out in some masculine hand, which had been committed to memory by the ambitious lady, and had afterwards flashed out as extempore elucidations of some dark, half-explored corner of modern science. It was even said that these little blocks of information got jumbled up occasionally in their bearer's mind, so that after an entomological lecture she would burst into a geological harangue, or _vice versâ_, to the great confusion of her audience. So ran the gossip of the malicious, but those who knew her best were agreed that she was a very charming and clever little person. [Illustration: "SCIENTIFIC PROOF."] It would have been a strange thing had Mrs. Esdaile not been popular among local scientists, for her pretty house, her charming grounds, and all the hospitality which an income of two thousand a year will admit of, were always at their command. On her pleasant lawns in the summer, and round her drawing-room fire in the winter, there was much high talk of microbes, and leucocytes, and sterilised bacteria, where thin, ascetic materialists from the University upheld the importance of this life against round, comfortable champions of orthodoxy from the Cathedral Close. And in the heat of thrust and parry, when scientific proof ran full tilt against inflexible faith, a word from the clever widow, or an opportune rattle over the keys by her pretty daughter Rose, would bring all back to harmony once more.
