“This :stione admits of ;a high polish, and is of a deep velvet-hlaek color. 
During .the last' year large quantities of it were obtained near Bluflfton, 
in Llano county, Texas, twenty-two miles from Burnet. The occurrence 
of this gadolinite was somewihat similar to that of allanite in Amherst 
county, Virginia. It has more than ordinary interest from the fact that 
it contains from 40 to 50 per cent, of yttria. About 1000 pounds were 
found in a single pocket, associated with xenotime, fergusonite, and eux- 
enite. One crystal weighed 11 pounds, another 13 pounds, and a single 
group weighing 40 pounds was obtained. The productions of this locality 
exceeded in quality and size anything yet obtained.”
