    of tbe old, so that; with the smallest outlay and the least possible trouble, you’ may have the greatest number of experiments—and these experiments of the most diversified nature possible, inasmuch, as we shall follow nature through her intricate meanderings studying those laws that regulate her progressive movements in giving birth to new productions. 22. HYDROGEN GAS—(4) ATOMIC, EQUIVALENT—1 —-is colourless, tasteless, fatal to animal life when taken into the lungs, it is the lightest of all bodies which are known to possess weight one hundred cubic inches, weigh only two grains and one- tenth, it is inflammable, but it extinguishes flame. 23. MINIATURE BALLOONS_Fill a bladder with the gas (4), and into its open extremity fix a common tobacco pipe; pre* pare some soap suds, such as children use to blow soap bubbles with; dip the mouth of the pipe’s head in them, and compress the bladder, globes of solution of soap filled with Hydrogen Gas will be formed which may be shaken from the pipe, and will ascend to the ceiling, this is a simple illustration of Aerostation, as this gas is the lightest of all gases, it is therefore, in other words, more bouyant, and on that account is best fitted for filling Balloons. 24. If one of these soap balloons, be overtaken in its flight by a lighted taper, it will explode, and give a vivid flash of light. 25. DETONATING BALLOONS.—Fill a bladder with two, parts hydrogen gas, and one part of oxygen gassoap balloons, blown with this mixture ascend slowly and explode violently, when touched with a lighted taper as in the last experiment. 26. THE PHILOSOPHER’S LAMP.—Put into a common beer bottle, the ingredients (4)—and cork it with a cork having a glass tube, or the stalk of a tobacco pipe, introduced about half an inch through it, and perhaps six or eight inches above and outside of it, in a short time the gas will be heard or seen rushing from the, top of the pipe, it is necessary to let all the common air escape beT fore you apply the light, because if it were not all expelled, it along with oxygen explodes violently (experiment 25, 26) and would blow the bottle to atoms. 27. PHILOSOPHICAL TRUMPET.—Take a tube from two to three feet in length and from two to three inches wide and open at both ends—bring it down slowly over the flame of the philoso¬ pher’s lamp, (26) and pleasing sounds resembling those of an YEolian Harp; will be produced, by raising and depressing the tubes grad¬ ually over the flame the musical chord may be greatly varied. 28. HYDROGEN GAS, EXTINGUISHES FLAME.—Fill a strong Phial that will hold about four ounces of water, with this gas; keeping its mouth downwards, introduce into it a lighted taper which has been burning some time previous, its flame will be extin¬ guished in a moment but the gas will burn at the mouth of the Phi¬ al with a pretty blue flame—when you withdraw the taper again, if
