Lecture given by WdF (and [[Mallet]] & [[Triboulet]]?), 18 April 1885, to the [[Société française de navigation aérienne]], after [[Salomon August Andrée]]'s discussion, in Stockholm on November 1884 to the Swedish Royal Academy ([[Kungliga Vetenskapsakademien]]), of his balloon ascent from Gothenburg on 14 July 1894.

This ascent had the special purpose of testing some of Andrées theories on the [[guide-rope]], conceived on a previous ascent on 18 November 1893 above the Baltic Sea. He gets into detail about the fabrication and set-up of the guide-rope itself, as well as the [[sail]] hung between the suspension circle and the balloon netting.

Andrée attached the guide-rope at different points on the [[suspension]] circle and measured the resulting deviation of the balloon from the direction of the wind.
