388 PROCEEDINGS OF SECTION B. 
Gilgoin meteorite, in the possession of Mr. Russell, F.R.S., 
Government Astronomer, Sydney, found on the station of that 
name, near Brewarrina, N.S.W. This weighs 674 lbs. and has a 
specific gravity of 3°857. It is very much more cracked and 
fissured and contains rather a larger proportion of nickeliferous 
iron than the preceding one, but in other respects closely resembles 
them. 
£li Elwah. This meteorite is also an earthy one, containing 
nickeliferous iron, with a chondritic or granular structure ; it 
weighs 334 lbs. and has a specific gravity of 3°537. 
Photographs and micro-photographs of sections of the four 
earthy meteorites were shown, as well as specimens of each. 
7.—NOTES ON SOME HOT SPRING WATERS. 
By A. Liversipcr, M.A., F.R.S., Professor of Chemistry, 
University of Sydney. 
(a) Lote upon the Hot Spring Waters, Ferguson Island, 
D Entrecasteaux Group. 
THE specimens forming the subject of this note were collected by 
Sir W. MacGregor, K.C.M.G., Governor of British New Guinea, 
who thought that these waters might prove to be of scientific 
interest, and therefore forwarded them to me for examination. 
Accompanying the specimens was the following description of 
the hot springs, prepared by Mr. Basil Thomson, together with 
two photographs of the locality :— 
“The evidence of volcanic action on the east end of Ferguson 
and Goulvain Islands in the D’Entrecasteaux Group were plainly 
visible from the sea, but a few miles to the westward gave place 
to a schistose slaty formation, of which the island seems mainly 
composed. It was, therefore, with no little surprise that, on the 
evening of our anchoring in Seymour Bay, we noticed a strong 
smell of sulphur, the fumes being sufficient to discolour the white 
paint on the vessel during the night. Seymour Bay lies in the 
narrow strait named by Captain Moresby after himself, and is. 
fringed with mangrove and dense scrub and backed by low hills. 
After forcing our way through mangrove and sago swamps for 
about half a mile, we came on a well-beaten native path, which 
led to a rapid stream. Some of the party who stopped to prospect 
for gold found the gravel in the bed of the stream too hot for the 
hands, although the water of the stream was cold. 
Making our way southward, we emerged from dense scrub. 
upon a flat, bare of vegetation, and dotted with little hillocks of 
pure sulphur, from which vapour was rising.
