Robert Hamilton Mathews,
The Wiradyuri and Other Languages of New South Wales
“ When the difficulties encountered in obtaining the grammar of any language which is purely colloquial are taken into consideration, I feel sure that all necessary allowances will be made for the imperfections of my work.The initiation ceremonies of the Wiradyuri tribes, which are of a highly interesting character, have been fully described by me in contributions to several societies and other learned institutions. ”
