Abstract
IN the past twenty years many hundreds of ultimate analyses and many thousands of proximate analyses of New Zealand coals have been made in accordance with British Standard Specifications at the Coal Section of the New Zealand Dominion Laboratory. A preliminary study of these analyses shows that New Zealand coals, varying in rank from peat to semi-anthracite (the anthracites are contact-metamorphosed lignites), almost all belong to a restricted range of coal type different from that of British and North American coals of Carboniferous age.
