Containing original experiments. The author found inter alia that he could produce 'highly elastic steam' by injecting 

 heated water into superheated steam. The above pamphlet was unknown to Poggendorff. 



The author constructed a new steam engine, invented a steam gun, improved the manufacture of welded wrought-iron 

 pipes (named after him), took cut the first patent for an ether ice-machine, and improved the process of steel-engraving 

 (siderography).

An account of the author's invention of a super-high-pressure engine, with boiler tubes of very small diameter, which 

 could be worked at a very high pressure with a minimum risk of explosion, and with great economy of fuel. But he 

 should be more remarkable now as a successful experimenter with the ammonia method of making cold.
