An installment of a serial report on the Textile Building at the 1900 Paris Exposition. It surveys the confusion among national systems for numbering yarn counts (silk, cotton, hemp, linen, combed and carded wool), with conversion formulas between French, metric and English systems, and mentions the planned international congress to standardize counts. It closes by describing the Lyons Chamber of Commerce's silk conditioning (drying) apparatus, from the 1840 inverted-bell stove through the 1883 and 1889 improvements, and promises a continuation.
