I was formerly a bookseller and binder, but am now turned philosopher, which happened thus:--Whilst an apprentice, I, for amusement, learnt a little of chemistry and other parts of philosophy, and felt an eager desire to proceed in that way further. After being a journeyman for six months, under a disagreeable master, I gave up my business, and, by the interest of Sir H. Davy, filled the situation of chemical assistant to the Royal Institution of Great Britain, in which office I now remain, and where I am constantly engaged in observing the works of Nature and tracing the manner in which she directs the arrangement and order of the world. I have lately had proposals made to me by Sir Humphry Davy to accompany him, in his travels through Europe and into Asia, as philosophical assistant. If I go at all I expect it will be in October next, about the end, and my absence from home will perhaps be as long as three years. But as yet all is uncertain. I have to repeat that, even though I may go, my path will not pass near any of my relations, or permit me to see those whom I so much long to see. To Faraday, who was now twenty-two years old, foreign travel meant much more than to most young men of equal age. With his humble bringing up and slender resources, he had never had the chance of seeing the outside world; he had never, to his own recollection, even seen the sea. When on Wednesday, October 13, he started out on the journey to Plymouth, in order to cross to the port of Morlaix, he began his journal of foreign travel thus:-- This morning formed a new epoch in my life. I have never before, within my recollection, left London at a greater distance than twelve miles. [Sidenote: A NEW ELEMENT.]
