<p><b>9.</b> <fld>(Geol.)</fld> <def>The folding back of strata upon themselves, as by upheaval, in such a manner that the order of succession appears to be reversed.</def>

<p><b>10.</b> <fld>(Chem.)</fld> <def>The act or process by which cane sugar (<i>sucrose</i>), under the action of heat and acids or ferments (as <i>diastase</i>), is broken or split up into grape sugar (<i>dextrose</i>), and fruit sugar (<i>levulose</i>); also, less properly, the process by which starch is converted into grape sugar (<i>dextrose</i>).</def>

<note>&hand; The terms <i>invert</i> and <i>inversion</i>, in this sense, owe their meaning to the fact that the plane of polarization of light, which is rotated to the right by cane sugar, is turned toward the left by levulose.</note>
