Fig. 4 shows a longitudinal section of a rootlet, which is understoodby the above description of the transverse section. Fig. 5 shows the starch granules highly magnified, probabl} two-thirds of the granules being of the size of 1-ah, while the remainder?are of the size l-cd. The granule 1-a measures 0*022 mm., while the smallest granulesmeasured j 0*0032 mm. 2 shows the appearance of a granule underpolarized light. A represents a transverse section of rhizome, of natural size. B 1 and 2 represent two ducts much magnified, 1 being a spiralduct from a rootlet, 2, a dotted duct from the rhizome. The external layer of cells in both rhizome and rootlet do not differmaterially from the others, being only slightly flattened. Chemical Examination.—Four pounds (avd.) of carefull}^ selectedrhizome were reduced to powder No. 50 and exhausted with strongeralcohol; the alcohol was removed l)y distillation, leaving a soft
