## Letters to the Editor The contact angles of brown coals are plotted with their oxygen content in Figure 2, where a fair rectilinear relation is observed. The two kinds of coals can bc classified on the basis of their atomic ratio O/C. The higher value of O/C > 0.15 of brown coal may imply a hig

A detailed chemical study has been made on a suite of 27 Australian coals of varying rank. The coals had a wide range of H/C values and, in addition to chemical analysis, were examined by Fourier transform infrared spectroscopy and 13C solid state n.m.r. The coals were reacted with hydrogen in tetra
