Two crystals were white, with almost no faces, save that the 
strong basal cleavage was very apparent. One of the smaller 
ones was about 10 mm. in diameter, and very much etched. It re- 
sembled the etched wine-colored crystals from Cheyenne moun- 
tain, Colorado. No other information was given about them 
than that they came from near Palestine, Texas, evidently from 
granitic rocks. 
This is the first occurrence of topaz noted in Texas; and its 
presence suggests that it may probably be found in connection 
with other minerals associated with topaz and peculiar to the 
Urals, Madagascar, Ceylon, and Oxford county, Maine. The 
crystals are believed to have been transported from some north- 
eastern point. 
DIAMONDS FROM WISCONSIN. 
In December, 1893, my attention was called by Dr. William 
H. Hobbs, professor of mineralogy and metallurgy in the Uni- 
versity of Wisconsin, at Madison, to a diamond that had been 
found in Oregon township, two and one-half miles southwest of 
Oregon village, in Dane county, Wisconsin. Through his cour- 
tesy, the stone was sent to me by the finder, Mr. Charles De- 
vine, of the place just named. The diamond was discovered 
by him while husking corn, in October, 1893, in a rough, stony 
field which had been under the plough for forty years. The 
bank of clayey earth in which it occurred contained a large 
number of rounded pebbles of quartz, but no other of the asso- 
ciated minerals of the diamond; and as the entire district con- 
sists of glacial drift coming from the north, a diamond-bed is 
not likely to exist in the immediate vicinity, but is rather to be 
looked for in the direction from which the drift came. The 
diamond is a rhombic dodecahedron, deeply pitted with circu- 
lar, elongated, reniform markings. In color it is slightly gray- 
ish-green. It is one of those diamonds, however, whose color 
often proves to be but superficial, and it would probably cut into 
a rounded stone. Its weight is 3.34 karats. This is the second 
authentic occurrence of diamond in Oregon, Wis., the other be- 
ing that of three small stones, the largest of which weighed 
25.32 karats, and was noticed in the report on the Mineral Re- 
sources of the United States for 1892, page 759. <A 16-karat 
diamond was reported to have been found, also in the glacial 
drift, at Waukesha, Wis., in 1884. Some litigation resulted 
from its finding, and considerable doubt was expressed at the 
time as to the genuineness of the discovery.
