BULL FINCH.—We must refer you to the answer above given to “A. M. B.” You will find plenty of designs for tile and china painting in the volumes of the G. O. P. You need not look further. WOULD-BE PROFESSIONAL.—Certainly, a livelihood could be made out of wood engraving, but then you should have more than one qualification for it. Practical skill, persevering industry, good sight, a firm, steady, yet delicate touch, and natural artistic taste. The work has the advantage of being home work, and needs little outlay—a good set of tools, and the boxwood blocks purchased as required. A skilled engraver can earn from £3 upwards a week. If you study at the South London Technical Art School, 122 and 124, Kennington Park-road, you will have £3 to pay per annum for fees, half-yearly and in advance. When you have acquired the art, illustrate some popular work or picture initial letters for articles, and little end sketches for the same, and take them to publishers as specimens. You might obtain advice at the central office of the City and Guilds of London Institute, Gresham College, London, E.C. The director and secretary is Philip Magnus, Esq. MISCELLANEOUS. YOUNG INQUIRER.—1. Yes, there is such a thing as a “singing flame,” and it is not like a singing kettle nor a windy gaspipe, and is as great a wonder as the fabulous “singing tree,” had that been real. A very delicate jet of flame, introduced through a small pipe into a narrow glass tube of a foot long, will respond to the singing of any one note, if set in tune to it. Professor Tyndall says, “With a little practice, one is able to command a flame to sing and to stop singing, while it strictly obeys the injunction. When the proper pitch has been ascertained the experiment is sure to succeed; and, from a distance of twenty or thirty feet, the flame when sung to is caused to sing responsively. If it do not respond, it is because it has not been spoken to in the proper tone; but a note of somewhat higher pitch causes it to stretch its tongue and sing vigorously.” 2. The 1st of April, 1869, was a Thursday. FAITH, HOPE, AND CHARITY.—See “Practical Hints About the Growth of the Hair,” in our part for July, 1885. The name Thames is derived from the Attic word _Tamh_, signifying “quiet,” the Saxon _Temese_, the Latin _Tamesis_. Possibly the latter may contain the origin of the name Isis, as given to the river at Oxford.
