This year and a half may be considered as the time of Faraday's education; it was the period of his life that best corresponds with the collegiate course of other men who have attained high distinction in the world of thought. But his University was Europe; his professors the master whom he served, and those illustrious men to whom the renown of Davy introduced the travellers. It made him personally known, also, to foreign _savants_, at a time when there was little intercourse between Great Britain and the Continent; and thus he was associated with the French Academy of Sciences while still young, his works found a welcome all over Europe, and some of the best representatives of foreign science became his most intimate friends. In May 1815, his engagement at the Royal Institution was renewed, with a somewhat higher position and increased salary, which was again raised in the following year to 100_l._ per annum. The handwriting in the Laboratory Note-book changes in September 1815, from the large running letters of Brande to the small neat characters of Faraday, his first entry having reference to an analysis of "Dutch turf ash," and then soon occur investigations into the nature of substances bearing what must have been to him the mysterious names of Paligenetic tincture, and _Baphe eugenes chruson_. It is to be hoped that the constituents of this golden dye agreed together better than the Greek words of its name. We can imagine the young philosopher taking a deeper interest in the researches on flame which his master was then carrying out, and in the gradual perfection of the safety-lamp that was to bid defiance to the explosive gases of the mine; this at least is certain, that Davy, in the preface to his celebrated paper on the subject, expresses himself "indebted to Mr. Michael Faraday for much able assistance," and that the youthful investigator carefully preserved the manuscript given him to copy. Part of his duty, in fact, was to copy such papers; and as Sir Humphry had a habit of destroying them, he begged leave to keep the originals, and in that way collected two large volumes of precious manuscripts. But there came a change. Hitherto he had been absorbing; now he was to emit. The knowledge which had been a source of delight to himself must now overflow as a blessing to others: and this in two ways. His first lecture was given at the City Philosophical Society on January 17, 1816, and in the same year his first paper was published in the _Quarterly Journal of Science_. The lecture was on the general properties of matter; the paper was an analysis of some native caustic lime from Tuscany. Neither was important in itself, but each resembled those little streams which travellers are taken to look at because they are the sources of mighty rivers, for Faraday became the prince of experimental lecturers, and his long series of published researches have won for him the highest niche in the temple of science.
