ternal and internal parasites
was made from birds, seals and fish.

Geology

(a) A geological examination of Macquarie Island was made by Blake.
The older rocks were found to be all igneous. The Island has been
overridden in comparatively recent times by an ice-cap travelling
from west to east.

(b) Geological collections at the Main Base. In Adelie Land the rocky
outcrops are metamorphic sediments and gneisses. In King George V
Land there is a formation similar to the Beacon sandstones and dolerites
of the Ross Sea, with which carbonaceous shales and coaly strata are
associated.

(c) Stillwell met with a great range of minerals and rocks in the
terminal moraine near Winter Quarters, Adelie Land. Amongst them was
red sandstone in abundance, suggesting that the Beacon sandstone
formation extends also throughout Adelie Land but is hidden by the
ice-cap. A solitary stony meteorite was found by a sledging party
lying on the ice of the plateau.

(d) In the collections made by Watson and Hoadley at the Western
Base (Queen Mary Land) gneisses and schists were ascertained to be
the predominant types.

(e) A collection of erratics was brought up by the deep-sea trawl in
the course of dredgings in Antarctic waters.

Glaciology

(a) Observations of the pack-ice, coastal glaciers and shelf-ice from
the 'Aurora' during her three Antarctic cruises.

(b) Observations of the niveous and glacial features met with on the
sledging journeys from both Antarctic bases.

Meteorology

(a) Two years' observations at Macquarie Island by Ainsworth

(b) Two years' observations in Adelie Land by Madigan.

(c) One year's observations in Queen Mary Land by Moyes.

(d) Observations by the Ship on each of her five voyages.

(e) Observations during the many sledging journeys from both
Antarctic Bases.

Bacteriology, etc.

In Adelie Land, McLean carried out many months of steady work in
Bacteriology, Haematology and Physiology.

Tides

Self-recording instruments were run at Macquarie Island by Ainsworth
and at Adelie Land by Bage.

Wireless and Auroral Observations

A very close watch was kept upon auroral phenomena with interesting
results, especially in their relation to the "permeability" of the
ether to wireless waves.

Geographical Results

1. The successful navigation by the 'Aurora' of the Antarctic pack
ice in a fresh sphere of action, where
