dextral shell

Conchol.: A spiral shell, whose whorls, when the mouth is placed toward the observer, turn from left to right. This is the general course in nature. Sinistral or reversed shells are those whose spires turn from right to left. In other words, when spiral shells are placed vertically with the spires uppermost, and the mouth toward the observer, the aperture in dextral shells is toward the right, and in sinistral toward the left. sin, as; expect, Xenophon, exist. ph = f. zhun. -tious, -cio us, -sious = shus. -ble, -dle, . = bel, del. 87 = and such as ariseth from a constant root in nature, we expect same in other animals, whose parts are IMG:content-2375.png:[blocks in formation] lead, .

It can be pro- duced by the action of dilute sulphuric acid on cane sugar, starch, cellulose, . It can be best obtained by boiling for several hours fifty parts of starch with dilute sulphuric acid (100 parts of water to five parts of H2SO4). The solution is then neutral- ized with chalk, filtered, boiled with animal char- coal to remove traces of color, and then evaporated carefully to dryne , forming an amorphous ma , which contains about sixty per cent. of dextrose, the remainder being chiefly dextrin.
