Gothard tunnel, begun in 1872, Prof. Colladon first introduced the injection of water in the form of spray into the compressor cylinder to absorb the heat of compression. This compressor was exhibited at the Centennial Exposition and was adopted by Mr. Sutro in the construction of the Sutro tunnel. A characteristic feature seems to be to get as much water into the cylinder as possible.
The gruels are so many that we must wish Mr. Woodhouse had known of the book. If the admixture of "wood-sorrel and currens" had seemed to him fraught with peril, he could have fallen back on the "Oatmeal Pap of Sir John Colladon." Where are all the old dishes vanished to? Who has ever known "A smoothening Quiddany of Quinces?" Who can tell the composition of a Tansy?
This day my wife showed me bills printed, wherein her father, with Sir John Collidon and Sir Edward Ford, have got a patent for curing of smoky chimneys. It is drawn in favour of John Colladon, Doctor in Physicke, and of Alexander Marchant, of St.
Two peasants visited this cave three times in the winter season, viz. on October 22, November 26, and on Christmas Day; and one of them, by name Chavan, drew up an account of their experiences, which was read by M. Colladon before the Société de Physique et d'Histoire Nat. de Genève in 1824.
Professor Pictet found himself sufficiently strong after a day's rest to pass on to Scionzier, and up the Valley of Reposoir, accompanied by the well-known guide Timothée, whose botanical knowledge of the district is said to be perfect. He had conducted MM. Necker and Colladon to the glacière in 1807, and believed that no savant had since seen it.
A dry compressor is that which introduces no water into the air during compression. Wet compressors may be subdivided into two classes. Those which inject water in the form of a spray into the cylinder during compression. Those which use a water piston for forcing the air into confinement. The injection of water into the cylinder is usually known as the Colladon idea.

But the first notable application of compressed air is due to Professor Colladon, of Geneva, whose plans were adopted at the Mont Cenis tunnel. The Sommeiller compressor was operated as a ram, utilizing a natural head of water to force air at 80 pounds pressure into a receiver.
