Warned by the consequences of my past folly, and beginning now to act, however imperfectly, by the only rule which will ever lead us to uniform justice, I had no sooner formed my resolution in regard to Sidney, than I gave him an opportunity of learning my sentiments. I will not deny that this cost me an effort, for I was afraid of losing a pleasant acquaintance; and besides, as the young gentleman was sentimentally in love, his little anxieties and tremours were really, in spite of myself, amusing. But vanity, though unconquerably rooted in me by nature and habit, was no longer overlooked as a venial error. I struggled against it, as a part of that selfish, earth-born spirit, which was altogether inconsistent with my new profession, and which except at the moment of temptation, seemed now too despicable to bias the actions even of an infant. Sidney was a man of sense; and therefore, by a very few efforts of firmness I convinced him that he could be nothing more. Nor did the explanation occasion even a temporary suspension of our intercourse. Unfortunately, his professional visits were become necessary to Miss Mortimer; and with me he had long before started a topic, amply compensating that which I had interdicted. He had an excellent chemical library, and a tolerable apparatus. By means of these, and a degree of patience not to be expected from any man but a lover, he contrived to initiate me into the first rudiments of a science, which has no detriment except its unbounded power of enticing those who pursue it. By informing me what I might read with advantage, he saved me the time which I might have lost in making the discovery myself; and though he had not always leisure to watch my progress, he could direct me what to attempt. After all, it must be confessed that my attainments in chemistry were contemptible; but even this feeble beginning of a habit of patient enquiry was invaluable. Besides, in the course of my experiments, I made a discovery infinitely more important to me than that of latent heat or galvanism; namely, that the prospect of exhibition is not necessary to the interest of study.
