Mr.. ALGER read paper on some new localities of
minerals showing that Pacolite found in Ire.
lsnd and Bohemia formerly, and minerals similar them
were now found in this country. Mr. A. here exhibited
specimens from those countries and America showing
an identity between them. Pacolite by some, was sup
posed to be distinct species and by others variety Of
chabsre with which agrees in OF character

FORM II cannot be doubted that the evidence of the

evidence had been shown in the case of the Irish or 30
hemian Pacolite. In one or two specimens found at
about three years ago he noticed this character
most distinctly The commou form of apacolite is low
double pyramid and that Of chabaste perfect
rhombohedron. He first met with this interesting mi.

the name Of Phts should 5be retained He regretted
no had no specimens to demonstrate this but in the
paper alluded to- he considered the evidence complete

OF Dr. Thenpson's analysis were not regarded Mr.. A.
