The area of the injection-valve of a marine steam-engine is stated at one square inch for every 10-horse jiower. This is said to be ample allowance inall cases, and is more than necessary when the in-jection water hiis a temperature of 52° Fah. Theaverage temperature of the Mediterranean is about65°; the Atlantic Ocean, at 20^ of latitude, about75° ; and at the equator, about 82 Fah. In-jector. A device for injecting a supply offeed-water into the body of a steam-boiler. In Gitlards injector this is ettected by the press-ure and condensation of steam from the boiler 2679, A, the ojieration of this ajipa-ratus. Steam esca
