Pacts of the very gravest import* ancc in connection with the health of the public arc revealed in the medical report on ethyl petrol the first section of which we are able to lav*before our readers to-day. This report, which is reproduced in P age 15, has been prepared for \Thc Daily Mail by Dr. Mycr Cop laus, D.S.O., 0.B.K., a doctor eminent in research work. I t is ? based on his own personal experi ' nienfs and the very valuable data supplied by the Research As sociation of `British Motor and Allied Manufacturers, who, ` on behalf of The Daily Mail, carried out a highly scientific analysis of exhaust gases from motor engines. Conclusions arrived a t as th e re su lt of these investigations, w hich have occupied over n in e weeks and are d ealt w ith in the first section of D r .

Conditions in narrow -streets with tall buildings in th e neighbourhood of traffic blocks, or in vehicular tunnels, become a m atter of the gravest con cern in this densely populated coun try. l LEAD DUST STICKY, I n in d u s tria l enterprises, th e rem ovai ot' lead dust, can only be effectively achieved by powerfully driven fans or suction apparatus.
