Abstract

This rock was first described by S. N. Wintle in 1875 as
eurite porphyry, which it had been termed by Professor G.
H. F. Ulrich, who, however, did not publish his description
until 1877. In 1875 also the late Chas. Gould wrote as
follows :

" Mount Bischoff is a conical eminence rising to about
2,500ft. above the level of the sea. ... It consists of
a small protrusion of a porphyritic rock having a felsitic
base, with granules and crystals of quartz and felspar ; it
weathers white, and is honeycombed or vesicular on the
surface, most probably from the decomposition and removal
of pyrites, which is freely disseminated throughout in places!."
