Two pages from the April 1912 issue of Posselt's Textile Journal. The main item continues the series on gauze or leno weaving, covering Jacquard gauze: rear-harness slackeners for whip-threads, threading plans for left- and right-hand doups, and the resulting crossings in the fabric (Figs. 35-43). The pages also carry the end of an article on rib weaves (Figs. 7-16) and a section of the series on fabric analysis, which describes burning and reagent tests for telling wool, silk and cotton apart.
