The fossilif erous formations of the River Murray cliffs have, 

 from their first discovery, been referred to the Tertiary epoch ; 

 and those of the South-East have been regarded by their 

 describer as with them forming part of only one deposit. The 

 Victorian geologists recognise different groups of strata in 

 their Tertiaries ; and have applied to them classificatory terms 

 such as are used by European geologists to designate the 

 primary divisions of the Tertiary epoch. Prof. Duncan 

 strongly condemns this practise, and advises us to speak of the 

 Australian Tertiaries, as older, middle, or newer ; and he has 

 set the example by calling the strata under review as Middle 

 Tertiary. But the very same grounds which justifies the 

 application of " Middle " will justify the employment of 

 "Miocene" or other term, which simply expresses the age of 

 the fauna relatively to that of our own shores. The principle 

 of classification introduced by Sir C. Lyell is equally applicable
