Concluding part of M. Luedtke's two-part article on the cell structure of vegetable fibers, focusing on chemical constitution. It describes extracting and separating the hemicelluloses (mannans, xylans) from cell-wall pulp with caustic soda and copper-ammonia solutions, and a proposed direct method for determining cellulose. It also covers the phloroglucin-hydrochloric acid color reaction used to identify the primary layer, with a table comparing bamboo, straw, wood, bast fibers and cotton. It closes with a summary of fiber structure (primary, secondary and tertiary lamellae, spirals, fibrils, lumen), illustrated by micrographs of bamboo and straw fibers and a labeled sketch.
