. Automotive industries . ation of a large number of flame photo-graphs indicates that there are four phases of velocityin a tube of uniform cross section. The first phase isknown as the phase of first acceleration. The secondphase is one of uniform velocity. The third phase isthat of second acceleration and the fourth phase is thatof a high uniform rate known as detonation. The first phase represents a condition which, if itwere possible to continue it throughout the entire rangewould result in the highest efficiency. In this phase thename is blue. In the second phase the flame becomesgreen.

In the second phase the flame becomesgreen. In the third and fourth phases the liberation ofenergy is so rapid that incandescence of some of thecarbon particles occurs and rapid loss by direct radia-tion takes place. The second phase represents the com-bustion of the most economical mixtures at loads at andunder those giving maximum economy, providing thatthere is no marked or incipient auto-ignition. This is atnearly full load performance and with lean mixtures in. Some members of Nominating Committee, left to E. Northway, A. W. Scarratt, H. W. Slauson. G. I Dorrls, Mark Smith, H. C.
