Her industry in teazing was not confined to Laura. She inflicted a double stroke, by the petulance or coldness with which she sometimes treated the De Courcys. But though Laura was keenly sensible to these petty wrongs done her friends, the injury passed them over without much notice. Harriet repaid them with laughter or sarcasm; while Montague seemed to consider them as wholly unworthy of attention. He continued his visits to Walbourne, and accident at last furnished an excuse for their frequency. In the course of Lady Pelham's improvements, a difficulty chanced to occur, which a slight knowledge of the elements of mathematics would have enabled her to solve. To supply the want of this knowledge, she had recourse to Mr De Courcy, who removed her perplexity with the ease of one conversant with his subject, and the accuracy of one who speaks to a reasoning creature. Lady Pelham was charmed! She was convinced that 'of all studies that of mathematics must be the most delightful. She imagined it might not be quite impracticable even for a lady, supposing she were so fortunate as to meet with a friend who could assist her.' De Courcy, laughing, offered his services, not, it must be owned, with any idea that they would be accepted. Her Ladyship, however, eagerly embraced the offer; for she was little accustomed to forecast the difficulties of any scheme that entered her brain. In this triumphant expectation that all difficulty would yield to her acuteness, and her brighter abilities gain in a comparison with the plain good-sense of her niece, she obliged Laura to join her in this new pursuit. Upon the study of this science, so little in favour with a sex who reserve cultivation for faculties where it is least wanting, Laura entered with a pleasure that surprised herself, and she persevered in it with an industry that astonished her teacher. Lady Pelham was, for a little while, the companion of her labours; but, at the first difficulty, she took offence at the unaccommodating thing, which shewed no more indulgence to female than to royal indolence.--Forthwith she was fired with a strong aversion to philosophers in bibs, and a horror at she-pedants, a term of reproach which a dexterous side-glance could appropriate to her niece, though the author of those memoirs challenges any mortal to say that ever Laura Montreville was heard to mention ellipse or parabola, or to insinuate her acquaintance with the properties of circle or polygon. Nothing moved by Lady Pelham's sneers, Laura continued her studies, impelled partly by the duty of improving the most valuable faculty of an immortal mind, partly by the pleasure which she derived from the study itself. It is true, that her Ladyship's indiscreet use of the secret, made Laura's labours the cause of much merriment to titterers of both sexes; but we have never discovered that De Courcy esteemed her the less for her persevering industry, or loved her the less for this new subject of mutual interest.
