448 Transactions.—G eology. 
It may, however, be remarked that some of the best known mineral waters 
of Germany are altogether tasteless. In any case an analysis would prove 
interesting. Ihave twice carefully observed the temperature of the springs, 
once in July, 1882, and again in July, 1888. On both occasions the day 
was cold and overcast. The following are the results in degrees Fahren- 
heit :— 
July, 1882. July, 1883.

It will be observed that the maximum temperature obtained was the same 
on both occasions.: Hence it cannot be due to any temporary increase of 
thermal activity at this place; but is probably to be attributed to the 
expiring heat of the volcanic agencies which formed the Lyttelton crater. 
Art. L.—On the Occurrence of some new Minerals in New Zealand. 
By 8. Herpert Cox, F.C.S., F.G.S., Assist. Geologist & Inspector of Mines. 
[Read before the Wellington Philosophical Society, 15th August, 1883.] 
Chalcotrichite. 
I Have to call attention to the occurrence in New Zealand of another 
copper mineral not hitherto found here. 
The specimen in question is the rhombic form of the red oxide of 
copper, known as Chalcotrichite, and it occurs as a number of fine acicular 
crystals in the ordinary red oxide or Cuprite at the Champion Copper Mine, 
Aniseed Valley, Nelson. 
This being the first time that this mineral has been found in New Zea- 
land, it is interesting to note its occurrence. 
Epidote. 
In July a specimen was forwarded from Greymouth for analysis 
by Mr. J. E. Warner, of which he states :—“* In the locality whence 
this was taken there are thousands of tons of boulders of the same 
material, most of them from a foot to two feet in diameter.” Mr. Skey 
determined this mineral to be Epidote, traversed by thin veins of quartz. 
It has a specific gravity of 9:464. Hardness 6 to 6*5, and is of a pale 
brown colour.
