As regards the general distribution of these volcanoes, we may 
here quote from a previous paper by one of us forming part of his. 
Presidential Address to the Linnean Society of New South Wales 
for 1895, pp. 155 - 156 :—‘The volcanoes of Victoria Land show 
a tendency to linear arrangement. From Mount Sabine to Mount 
Melbourne the trend is south-south-westerly. Mount Erebus and 
Mount Terror lie almost due south of Mount Sabine. Further 
north from Mount Sabine the great earth-fold, on the septum of 
which this chain of volcanoes is situated, probably bends a little 
westwards, as shown partly by the surroundings, partly by the 
position of Balleny’s Island. North-west of Balleny’s Island the 
great fold trends perhaps to the knotting point between the Tas- 
manian axis of folding, described in the address just referred to, 
and that of New Zealand, the former perhaps running through 
Royal Company Island, and the latter through or near Auckland 
Island and Macquarie Island. The knotting point would probably 
be somewhere (approximately) near the intersection of the 60th 
parallel of south latitude with the 150th meridian of longitude 
east from Greenwich. It would thus join the line of extinct 
volcanoes along East Australia on the west, and perhaps the 
active volcanic zone of the North Island of New Zealand, or ab 
all events the fold which bounds that continent, on the east. 
Traced in the opposite direction, the volcanic zone probably 
runs through Seal Islands, the active volcanoes of Christensea 
and Sarsee, and through Mount Haddington, an extinct voleano 
in Trinity Land, to Paulet and Bridgman Islands, active volcanoes. 
The volcanic zone bends easterly from here on account of the 
easterly trend in the fold, which appears to make a loop towards 
South Georgia before it swings back towards Cape Horn. That 
there is a real easterly trend in the earth-fold at Trinity Land
