Gerard Troost — Glenn. 8i 
as they came to his hands from other sources has worked an 
injustice to Troost that cannot now be remedied. It cannot 
now be known whether Hall was prompted to act as he did 
simply by the desire to take for himself the credit of describ- 
ing the new species or was prompted by some personal feel- 
ing toward Troost since the latter, as was well known then, 
strongly deprecated Hall's custom of giving local names to 
geological formations and refused to use these names for the 
same formations as they occurred in Tennessee. The Smith- 
sonian Institution has promised through Prof. Schuchert as 
above quoted, to render what partial reparation is now pos- 
sible by the early revision and publication of the memoir. 
Dr. Troost's museum was a notable one for its time. 
Some years before his death he disposed of his collections 
in comparative anatomy and sent to Europe his material 
in zoology and botany. At his death it contained 13.58:2 
specimens of minerals, 2,851 in paleontolog\% between 2.000 
and 3,000 rocks, shells — not numbered, and many Indian 
dresses, ornaments, weapons, and relics from mounds. Un- 
successful efforts were made to have it purchased for the 
University of Nashville, then by the city of Nashville, and 
later by the State. It was finally sold in 1874 to the trus- 
tees of the public library of Kentucky after examination and 
recommendation by Dr. J. Lawrence Smith and Dr. Yandell. 
The $20,500 paid for it was raised by five lottery drawings, 
the "little sin in the matter of the thing" being excused, as 
the public library paper of Louisville said, by the great good 
growing out of it. The collection is at present housed in 
the library's building in Louisville, Ky. 
The writer understands that Dr. J. Lawrence Smith 
ater secured the meteorites in the collection from the trus- 
ees of the library. 
As a geologist. Dr. Troost had done considerable work 
m the region accessible from Philadelphia while a resident 
there. 
Along with Lesueur he first pointed out to the miners in 
Missouri the true nature of calamine and discovered the 
existence of cobalt ore there. He early delimited the coal 
area of Tennessee and directed attention in his various re- 
ports to many of the mineral resources of the state that
