 With the exeception of the section noticed by us in a previous 

 paper (1), there does not appear to be any fossiliferous exposure 

 of Eocene I'ocks between the viaduct and tlie limestones below 

 Batesford. In the same paper we described the nature of the 

 beds displayed in the river sections between Hope's Mill-dam and 

 Fyansford, and subsequently again referred to the section 

 displayed at M'Cann's Filter Quarries (2, p. 193), and gave a list 

 of fossils from the clays of the section (4, p. 161). 



The question of the difference of level of the lava on the two 

 sides of the Moorabool, between Batesford and Fyansford, we 

 alluded to in a previous paper (1). It seems probable that the 

 lava to the west, occupying the lower level, is younger than that 

 capping Orphanage Hill, the latter being a southerly extension 

 of that capping the Miocene beds near the viaduct. This 

 suggestion would, of course, imply great denudation over a 

 considerable area after the effusion of the Orphanage Hill lava. 

 From a careful examination of the district we do not think that 

 it can be due to faulting, although faulted marine tertiaries 

 occur at no great distance, namely at Waurn Ponds and at 

 Curlewis. At the former place the limestone at M'Cann's old 

 quariy is cut off to the southward by a vertical fault, the amount 

 and direction of the displacement not being known, and the 

 quarry is abandoned, while the slight sei'ies of step faults at 

 Curlewis we have described elsewhere.
