Abstract
The writer has recently had the opportunity to examine a specimen of granite from Cashes Ledge, a submarine prominence in the Gulf of Maine. The specimen was collected by Dr. John M. Zeigler of Woods Hole Oceanographic Institution. Although the precise location of the specimen is not available, reference to topographic maps of the area (Murray, 1947, Fig. 7) indicates that the position must be approximately 42° 54′ N. Lat., 68° 56′ W. Long.
