THE GLEN OHM IS T 0 N METEOIUTE. 
(>9- 
analysis of the Thunda meteorite of Queensland and with the analyses of iron 
meteorites from Gladstone in Queensland, from Mount Edith in Western 
Australia, from South Australia, from Narraburra in New South Males, and 
from Cranbourne in Victoria. 
The general description by Professor Liversidge of the Thunda meteorite 
corresponds closely with that of the Glenormiston meteorite, and as the chemical 
analyses are so similar it is not at all unlikely that they constitute portions 
of the same original mass, although found approximately 300 miles apart.

The chemical analysis shows nothing abnormal or unusual in any way, 
and is closely comparable with that of several iron meteorites from Australia 
and elsewhere. 
In comparison with the average composition of iron meteorites it appears 
to be a little deficient in cobalt but much richer in phosphorus, sulphur, and 
carbon. Such a comparison, however, may be deceptive as it is not likely that 
there is a linear variation of the constituents of iron meteorites, and comparison 
with an average composition may be very misleading.
