A two-page installment of E. A. Posselt's "Fabric Analysis" series, continued from the July 1917 issue. It describes yarn examining machines (A. Suter, Henry L. Scott & Co., Chas. H. Knapp) for checking yarn evenness, and methods for finding yarn counts by comparison, including a microscope and twisting apparatus. It also covers measuring thread diameter with a worked square-root rule for cotton, wool, worsted and silk, and begins a section on identifying and separating fibres by chemical analysis.
