TABLE 75.-Specific rotation ([a]) of certain sugars at various concentrations 1 Calculated from Gubb's equation. Ber. deut. Chem. Ges. 18, 2207 (1885). TABLE 77.-Coefficients' in the Creydt raffinose formula [If both polarizations have the same temperature, use column bc. If polarized at different temperatures, multiply b at t (of direct polarization) by cat ta (of invert polarization). To the whole denominator, add 0.000794 (m-13), in which m is the dry substance taken for inversion and contained in a final volume of 100 ml]. TABLE 78.-Reducing-sugar values by the Munson and Walker method [The original values of Munson and Walker have been redetermined and the values in this table for dextrose, invert sugar, and the sucrose and invert-sugar mixtures totaling 0.4 and 2.0 g are the values redetermined by Hammond.' The values for levulose and the 0.3-g total-sugar mixture of sucrose and invert sugar are new values determined by Hammond. The values for lactose and the two lactose and sucrose mixtures are those of Straughn and Given,' which have been calculated to even intervals of copper. The values for maltose are those determined by Walker'] TABLE 78.-Reducing-sugar values by the Munson and Walker method-Continued [The original values of Munson and Walker have been redetermined and the values in this table for dextrose, invert sugar, and the sucrose and invert-sugar mixtures totaling 0.4 and 2.0 g are the values redetermined by Hammond.'
