[A] For illustration of the present article a 200 Jacquard machine is used, illustrated on pages [11-17] by [Figs. I. to XI.], which contains the same principles of construction as any other size machine. These illustrations are drawn one-fourth of the actual size; hence, any measures, etc., we have omitted may readily be found by any student.
