the fact that its mode of occurrence and mineral character favour the 
conclusion, I am inclined to think that this deposit of brown hematite 
is nothing more than the gossan of some very large pyritous lode. It 
has been estimated that 52,893,058 tons of the ore are exposed at the 
surface. 
The other important deposit of brown hematite was discovered by Mr. 
McKay in 1878, at Mount Peel in the Nelson district, and contains 
54 per cent. of metallic iron. The ore, which is a dark-brown com- 
pact one, is associated with fine-grained breccias, dark slates weathering 
white, and heavy beds of compact blue crystalline limestone which overlie 
the great series of breccia beds and conglomerates which form the western 
part of the Mount Arthur range. Where the specimens were obtained the 
bed was about 50 feet thick, and isolated masses 10 feet to 15 feet across 
were also observed; while to the north of the Takaka a much greater 
development takes place, and diggers report the ore in this locality to be 
about a mile in width 
Besides these important deposits many specimens have been received at 
the Museum for identification or analysis, from the following localities :— 
Pitt’s Island; Thames; West Coast; Makara, Wellington; Kawau; the 
Bluff; Raglan; Riwaka, Nelson; Big Muddy Creek, Manukau; Whare- 
kawau ; Wangaroa North; Manawatu Gorge; Paringa River; and Tawa 
Flat; and these have yielded from 29 per cent. to 60 per cent. metallic 
iron. The details of these analyses are included in the Colonial Laboratoy 
Reports and the Manual of the Mineral Resources before-mentioned. 
Chloropal, Ee Si?—Professor Liversidge (Trans. N.Z. Inst., vol. %-, P- 
497) mentions the occurrence of this mineral in New Zealand, presented to 
the Otago Museum by Captain Fraser. The following is his description of the 
specimen :—‘‘ Of a yellowish-green colour; somewhat foliated cone-in-cone 
structure; sectile, soft; easily polished, even by rubbing with the thumb ; 
adheres slightly to the tongue: when immersed in water gives off air- 
bubbles, and becomes translucent. Before the blowpipe does not deerepi- 
tate; blackens immediately, and fuses with difficulty on the edges, with 
slight intumescence, to a black glassy slag.” 
Siliceous Hematites.—Besides the foregoing ones, dere are a few in- 
stances of hematites oceurring in which the percentage of silica is 80 high 
as to make it advisable to class them under a different head. These ores 
are generally of a rusty-brown colour, of varying degrees of hardness, and 
seldom contain more than 20 per cent. ee
