There are eleven Zincite specimens, with the exception oftwo artificial specimens, all from Sussex Co., New Jersey. These,one suspects, have been carefully selected and of course the crys-tallized examples are very precious. There is a zincite enclosed incalcite, in long cylindrical stringers, one bag-shaped mass with pe-cuHar pressed surfaces.
