encountered in the deep levels of the Kapanga Mine, Coromandel, may 
be quoted : Fixed carbon, 41-6 per cent. ; volatile hydrocarbon, 6-4 per 
cent. ; moisture, 3-0 per cent. ; ash, 49-0 per cent. Analyst, H. E. Met¬ 
calfe, Thames School of Mines. Mines Report, Pari. Paper C.-3, 1900,

Samples of quartz from the Waihi Gold-mine have been found on 
analysis to contain small amounts of free carbon, but it is not known 
whether this is in the form of graphite or not. 
32. Mangawhare, North Auckland. —A sample of graphitic material in 
the Canterbury Museum is labelled as from Mangawhere (presumably 
Mangawhare). 
33 Rangiahau, Hokianga County. —In 1902, Mr. J. Ogle forwarded 
from Rangiahau a sample of impure graphite which had the following com¬ 
position : Water, 1-6 per cent. ; graphite, 44-8 per cent. ; earthy matters, 
53-6 per cent. Lab. No. 36, 1903, p. 6, No. 9415. 
34. Miscellaneous Occurrences of Graphitic Rock. —The reports of the 
Colonial or Dominion Laboratory mention a number of graphitic samples, 
analyses of which are not published. In most cases, however, analyses 
or notes relating to the samples are no doubt recorded in the Laboratory 
manuscripts. Though not complete, the following list, selected from 
Laboratory reports, may be of some use, as indicating localities where 
graphitic material occurs. The numbers in brackets are the Laboratory 
numbers.
