The iron gauze case has the standard number of apertures, i.e., 784 to the sq. in., and it is 'capped," i.e., it has a second or smoke gauze outside the first where the greatest heat is. The case is set in a brass ring, screwed eccentrically to the top of the reservoir, and three upright wires extend from it to form a loop for the carrying ring. There is no lock
