First-Chemical illusions, or those phenomena which may be traced to the operations of chemistry as their source; such, for instance, as the spontaneous combustion of bodies, both animate and inanimate, the art of breathing flames, walking on red-hot iron, the methods of forming sympathetic landscapes, magic prints, &c. Secondly-Optical illusions. Under this head we shall treat of the Fata Mogana-of supposed apparitions, &c. Thirdly-Acoustics and aural illusion, embracing the subject of echoes. And, lastly-Mechanical feats and contrivances. Thus, the principal phenomena of nature, and the leading combinations of art, which bear the impress of a supernatural character will pass under our review; and our attention will be called particularly to those singular illusions of sense by which the most perfect organs either cease to perform their functions, or perform them faithlessly; and where the efforts and the creations of the mind predominate over the direct perceptions of external nature. In pursuance of the course thus marked out, we shall proceed in our next to consider the subject of chemical illusions, or those phenomena which may be traced to the operations of chemistry as their source. G. T. F. In the days of Nero, glass perfectly transparent was reckoned so valuable, that Nero gave a sum equal to £50,000 for two glass drinking-cups with handles. And that porcelain was so esteemed by the Romans, that after the taking of Alexandria a porcelain vessel was the only part of the spoil retained by Augustus. J. H. There is a boiling fountain in Iceland from which the water is thrown to the height of 90 feet, and is still boiling hot when it falls to the ground. It is to be supposed therefore, that the water in this reservoir must be much hotter than the boiling point of water. J. H. It is not generally known, that the red-hot balls employed by the garrison of Gibralter to destroy the Spanish floating batteries were carried from the furnaces to the bastions in wooden barrows with only a layer of sand interposed; and this was found sufficient to prevent the balls, though in a high state of incandescence, from setting fire to the wood, sand being a very slow conductor of heat.

How sometimes nature will betray its folly, SHAKSPEARE. PREFATORY ADVERTISEMENT. This Drama was written for the purpose of illustrating a particular conception. The eccentricity of its plot is accompanied, in some instances, as applicable to the character, by a peculiarity of language, and a morbidness of opinion. The reader, when he peruses the opinions and expressions of Hugo Steilfort, will be pleased to remember what he is-a being removed from, though understanding, human impulse and feeling. In shadowing forth a Fiend, the writer has attempted to give his view of how the character should be represented. The sentiments which are put into his mouth are, of course, put there only so far as they may be supposed to be characteristic. The writer, in colouring his portrait, has been obliged to make use of an exclusive selection of dark tints, some deepening into blackness→→→ others brightening into lurid and Stygian illumination; but all of the one order, and, if presenting variety, changing their hues like the scales of a snake-now jet, now sulphuric azure, now ghastly and glittering green, and now the glow of brightening embers-an iris of infernal radiations. The reader will be kind enough to look at the moral of the composition, and attribute the jaundiced principles of Hugo to the blackness of his designs and character. The Drama is in no way adapted, or intended, for represen tation. DRAMATIS PERSONE. LYNDERT DE LOEL, Count of Ffalzberg. BERTRAM bearing the name of Hugo Steilfort, his friend.

Hugo.-One would suppose the elements themselves, Shrill tides of whistling hail, and clouds on clouds I've tried to pierce the thickets that around me Twigs in my visage, till I gave it over. The howling surges of a swollen river Stream on my right hand, and, sooth, on the left, I hear the wail of wounded wolves, struck in The flanks by falling branches. Is it spite? And stars, like jewels, glitter'd; but I had Scarce master'd two leagues of my 'nighted journey, I well could laugh at, for I've ere this heard That which would shame these grumbling voices unto E'en in the sequel of my expedition, In sight too of my object, is provoking.
