MINERALOGICAL NOTES FROM RECSK.

only. They are partly developed on the one end of their principal axis, 
almost exclusively colourless and have, on the whole, a length of Ua—8 mm., 
reaching exceptionally a thickness of 5 mm., and partly are, overbridging 
the cavities, grown on with both ends. The latter reach a length of 
10 mm. and a width of almost 5 mm., and, in consequence of rents, 
seem more or less gloomy. The terminal faces are of a mirrorlike smooth¬ 
ness, while the prism faces show, with scarcely any exception, unevenesses 
and are often, respectively in the case of crystals which are grown on with 
both their ends, always vertically striated. 
I further consider worthy of mentioning the fact that Recsk is the 
third of places where Whewellite, known chiefly from coal-mines, may 
be found in ore-mines. Up tu now it was only known as originating from 
ore-mines, for instance from Freiberg 1 and from Urbeis in the Vosges. 2 
The Sulphur forms rarely sulphur-yellow, mostly honey-yellow crystal¬ 
line masses of a smaller size, on which, sometimes, crystal faces were 
to be observed, but I could not detect any free crystals. With regard to 
its occurence, of which I made mention in connection with Whewellite, 
I may further notice that I mostly found it in direct contact with 
Whewellite, the crystals of wich it is sometimes surroundig, being a more 
recent formation. 
The Dolomite crystals mentioned in connection with the second 
occurence of Whewellite are tabular along the basal pinakoid, grown on 
with the sides of their tables, of a hardly noticeable yellowish colour and 
totally transparent, The rhombohedral faces are very bright, the often 
uneven basal planes are less brilliant. 
In closest vicinity of Dolomite veins containing Whewellite and 
Sulphur, I found some almost black cristalfragments of Sphalerite in the 
above mentioned conglomeratelike rock, the former being known only as 
a sporadically occuring 3 mineral from Recsk. 
With regard to Enargite, Pyrite, Quartz and Dolomite originating 
from the „Középső-György“ adit, I may mention the following: 
The crystals of Enargite occur in greatly altered, silificated Riotite- 
amphibole-andesite, respectively in hornstone, or in the cavities of crystal¬ 
line Enargite, sometimes by themselves, but mostly associated with
