The principle of the diving-bell may be illustrated by taking a tumbler, inverting it, and pre ing it down into a ve el of water, when it will be seen that, although the water will rise in the tumbler to an extent proportioned to its degree of immersion, yet the upper part of the tumbler will remain perfectly dry, and if a lighted taper be placed within, it will not be extinguished, but will, on the contrary, burn with even increased energy, owing to the condensation of the air by pre ure. Diving - bell pump : A pump having a casing divided by a vertical partition into two chambers, which are provided with inwardly and outwardly opening valves. The chambers are kept partially filled with water, which, together with air, is "Wot ye not that such a man as I can certainly divine?" admitted to each through the inwardly opening -Gen. xliv. 15.

This is effected by the alternate reciprocations of a piston working in the open-ended cylinder, which, at each stroke, draws a portion of the water from one of the chambers into the cylinder, lowering its level in that chamber, and permitting the air to enter through the inwardly opening valve; the return stroke causes the water to rise, forcing some of it, together with the air, into an exterior chamber, whence it is carried to a condenser, and thence, For the difference between to divine and to through a tube, to the bell.

A waterproof clothing and helmet for those who make submarine explorations. In the old forms of diving-dre the air filled the space between the body of the diver and his impervious clothing, the expired air escaping by a small valve in the hemlet, through which any exce of air also escaped. Irregularity in the action of the pump caused also irregularities in the escape of the bubbles, and thus the a istants might for a long time unconsciously continue to send air to a corpse. In the new apparatus, the appearance of the bubbles indicates the safety of the diver, and the a istants on the watch are at any time warned of his danger by their non-appearance. ( Knight . ) diving-spider, s. Zool.: A spider ( Argyroneta aquatic a), which though fitted only for aerial respiration, yet constructs a dwelling shaped not unlike a diving-bell, at the bottom of shallow water, carrying down air by means of the hairs with which it is clothed.
