D. T. Kilburn, Esq., presented two framed Daguerreotype pictures of 
three Aborigines of Victoria, and mentioned the extreme difficulty experi- 
enced in getting them to sit a second time, as upon seeing their likenesses

Dr. Officer drew attention to a similarity in the venation and structure 
of the leaves of the gutta percha tree upon the table, and in those of the
