The following Catalogue of the Minerals known to occur and
recorded from this Island is mainly prepared from specimens
contained in my own collection, and in the majority of instances I
have verified the identifications by careful qualitative analysis.
It cannot claim any originality of research, or even accuracy of
detail, but as the material has been so rapidly accumulating during
the past few years I have thought it well to place on record the
result of my personal observation and collecting, which, with
information gleaned from authentic sources, may, I trust, at least
pave the way for a more elaborate compilation by a more capable
authority
