Tertiary ])erio<l, there must liave been, on the wl)(jle, a 

 warm climate, and during that })eriod it would be impossible 

 to expect that any glacial phenomena could have been 

 produced. Besides this, no shells had been found that 

 would indicate Arctic conditions. It was well known that 

 in the glacial till of Europe, Arctic shells were frequently 

 found, and it was possible to trace these deposits by the shells. 

 Where then could the Tertiary glacial epoch of Victoria 

 be placed ? PalfPontolog•icali3^ there was no room for it. It 

 might perhajjs be mentioned that the sea was certainly close 

 to Bacchus Marsh during Tertiary times. Undoubted 

 evidence of this had been given by Mr. Reginald Murray in 

 one of his reports. A statement had also been made that 

 the pebbles, &c., which had been found, were not known to 

 exist in Victoria. He would like to know what these were, 

 for no list of rocks was given as those not found in any 

 other part of the colony. Then again, amongst these rocks, 

 granite, schist, felspar and sandstone were mentioned, but no 

 mention was made of the Tertiary limestone oi' any rock of 

 undoubted Tertiary age. If this were a post-Miocene or late 

 Tertiary deposit, he thought we should have some of these 

 rocks amongst those which had been transported. 



Mr. James Dunn said that the conglomerate w*ljich he 

 regarded as of glacial origin lay at the base of the coal measures. 

 If the conglomerates that he described were the same as 

 those described by the authors of the paper, it was out of the 

 question to speak of roches moutonnees. In fact those who 

 had passed through Bacchus Marsh would have observed the 

 rounded appearance of the liiils. This was characteristic tf 

 the Mesozoic deposits of every part of the colon}- , and was 

 certainly due to diluvial action, and he did not think any 

 weight could be laid upon that chaiucteristic feature of the 

 landscape as indicating any glacial action whatever. He 

 was glad the matter had been brought forward, and the 

 authors of the paper had done veiy good service in making- 

 such earful observations, which would enable those who 

 wished to do so to examine the spots referi'ed to for 

 themselves. 



Professor Spencer said that, twelve days since, he had 

 gone with Mr. Dunn to the de))osit he had described, for tlie 

 purpose of being shown what were undoubtedly roches 

 moutonnees. There could not be the slightest doubt about 

 the presence of these at Derinal.
