doubted descloizite. The very small crystals, grouped somewhat 
like the common crystallizations of calamine or prehnite, hada a 
columnar fibrous structure, distinct columnar cleavage, dark- i 
brown color and resinous luster, with hardness 3.5, and s ci

Before the blowpipe it gave reactions for vanadium, arsenit, f

It differs from descloizite in having part of the vanadic acid 1 
placed by arsenic acid. The analyses, as well as all the phys! 
properties of the mineral, show such a close resemblance to trito : 
chorite that it is very possible that they are identical, and sho 
both be considered as arsenical varieties of descloizite. 
Gorp ın Norta Carouina—At a recent meeting of the AG 
emy of Natural Sciences Professor H. Carvill Lewis exhi 
some remarkable gold nuggets found in Montgomery coun 
C., forty miles east of Charlotte and two miles from Yadkin 
Some of the nuggets were of great size. One of them wel 
over four pounds, and contained nearly $1000 worth of gold. 
was finer than any specimen in the collection at the U.S. Mia 
was probably one of the largest nuggets ever found in 1 
America. Many of the specimens exhibited were of nearly P 
gold of a crystalline structure, and of a fine golden yellow 
It was stated that in the district of North Carolina, whence 
nuggets were taken, gold is very abundant. The larger ™ 
were found in the gulleys, where they had been washed out 
decomposed rock, and it had been stated that a shovelful oF 
dug out of the hillsides anywhere in the district would pañ 
traces of gold. Some years ago one man took out of a hol 
teen feet square $30,000 worth of the precious metal. The 4 
zite containing the gold occurs in a white clay or decomp” 
schist.
