In either of thefe cafe?, the water is attracted by the glaft only on one fide ; but if another piece ot glafa be placed in oppolition to the former, and in contact with the Him of water, the water will be attracted and ret ;uned with a greater force ; and if the water be on every fide encompaffed with glafs, or tnclofed in a narrow tube, the attraction will become flronger, becaufc the fur- face of contact in proportion to the quantity of water is thus conliderably enlarged. The truth of thefe may be evinced in the following mariner. Put water into a glafs veffel, {Plate I. , fig. i.) and the water near the furface of the glafs will afcend, and form a curve, as at A and B ; or the fame effect will be exhibited at C and D, by dipping part of a piece of glafs in the water, fa order to explain this effect, let A B, (Jig. 2.) reprefent a lection of the furface of a piece of glafs, the lower part of which is iminerfed in the water, B C : and fuppofe this iurface to be divided into a number of indefinitely fmall parts, a, b, c, d, &c. ; then the part a, next to the fur- face of the water, B C, will raife a quantity of water pro- portional to its attractive force ; which quantity is thus brought nearer to the part b of the glafs, and attracted by- it, fo that another quantity of water takes its place next to a. The firft quantity of water being raifed to b, is brought nearer to the part c of the glafs, and being attracted by it, is raifed to the place c, whilft the firft quantity of water a, takes its place, which is fucceeded by another quantity of water whi
