Les ballons dirigeables : expériences de m. Henri Giffard en 1852 et en 1855 et de m. Dupuy de Lôme en 1872
A short French technical account by Gaston Tissandier of Henri Giffard's 1852 and 1855 steam airship trials and Dupuy de Lôme's 1872 dirigible, published in Paris by E. Dentu for readers following aeronautical experiments. Wood engravings show elongated gasbags in dense rigging nets, a top-hatted aeronaut at a steam engine on an open gondola, and balloons above flat countryside — useful for line-drawn aircraft silhouettes and cordage patterns.
