[Letter from Mr. S. H. Wintle]:

"The newer basalts, which in Victoria have filled up so
extensively Miocene and Pliocene valleys, and river channels,
are chiefly vesicular Zeolitic <i>dolerites</i> and
<i>anaemesites</i>, the former being well represented by the
light-coloured Malmsbury `bluestone' so extensively employed in
buildings in Melbourne."
