The minerals here described are all from localities not previously mentioned in the literature. They were collected while the writer was teaching at Brown University in 1915-16. The apatite was measured on the two-circle goniometer at Harvard University, and thanks are herewith extended to Professor Palache for his assistance in working out this crystal. The aid of Dr. Edgar T. Wherry in the calculation and drawing of the epidote and hematite is also gratefully acknowledged.
