Experiments are being made in Lon don with petroleum in solid state for fuel purposes, the crude oil being mixed with a chemical compound equal to about fifteen per cent of its weight and bnjested to a moist sheat of about 212 degrees, after which it is dried at high temperature and com pressed into the form of bricks by a powerful press. The fuel in this form, when buried in an ordinary grate, pre sented a bright flame of intense heat, without giving off any liquid and leav ed little ash. taste made are said to have been very successful, the blocks being equal to coal in hesting power, without being liable to spontaneous combustion, and no,clinkers when burned.—New Man Deltas.
