A continuation of E. A. Posselt's 'Fabric Analysis' series from the May 1916 issue of Posselt's Textile Journal. It covers identifying artificial silks (Chardonnet, viscose, cuprammonium) under the microscope and by their manufacture. It also describes burning tests to tell wool, cotton, linen, true silk and weighted silk apart, plus tearing tests for linen versus cotton. Illustrated with micrographs (Figs. 44-50). The last page carries an advertisement for a silk dyeing company and short items on artificial silk treatment and old German dyes.
