Ourpages bear ample evidence of the great amount of ef-fort which is being devoted to this task, and we aimto record every considerable step which is made to-ward its accomplishment. Petroleum may be burn-ed for illuminating purposes in lamps, without anydifficulty, so long as the lamps remain stationary, butsome of the best of these lamps always begin to smoke. when they are carried through the air, or when theyare encountered by slight drafts. To obviate this dif-ficulty is the object of the invention here holes for the entrance of the air to feed theflame are surrounded by a cape, A, which extendssome distance down the sides of the lamp, leaving aspace between the cape and the lamp. Bibs, B B, arefastened upon the outside of the lamp, and extend tin- der the cape to guide the air, which may be passingacross the sides, directly into the holes, and thusprevent the cross currents, which produce the smoke. Fig. 2 represents a lantern constructed on the sameprinciple, to prevent unequal currents or puffs of air,as the lantern is moved up and down. The lamp, C,is surrounded by an external casing, d, with a spacebetween for the passage of the air to feed the casing, d, is enlarged at the base, and the airpassage is crossed by two diaphragms, one, e, perfora-ted with holes, and the other, /, being merely a diskof metal ex
