surface or a slight striation, are found in tlie Upper Marine Beds, 

 Occasionally too, the beds immediately underlying such a block 

 have been indented, showing that the block has been dropped 

 from above. At Derrinal, Victoria, such an erratic of granite 

 weighing 30 tons, and having its upper surface grooved and 

 smooth, is embedded in mudstone. A picture of this vrill be 

 found in this case. Similar evidence has been found in rocks of 

 the same age in South Africa and in Southern India. 



In South Australia there is evidence to show that a glacial 

 epoch took place as far back as Cambrian times. 



Glacial ice has existed in the Kosciusko Ecgion in com- 

 paratively recent times. The evidence, which is very perfect, 

 comprises glaciated surfaces, moraiues, &c. A scratched boulder 

 is exhibited here, and photographs will be found on the west 

 wall. 



JSTumbers of small erratics from this and the other States are 

 exhibited together with some striated pebbles from America 

 (Pleistocene Ice Age) and Switzerland (existing glaciers) for 

 comparison.
