point where the rocks are most crystalline and homogeneous 

 in character. This evidence consists of the discovery of bone 

 breccia in what I believe to be the cooling joints of an older 

 sheet of basalt. From close personal examination of the 

 bones in situ, and from rei^lies made by Mr. Moore, the 

 intelligent overseer of defence works, — who first, through 

 Mr. Roblin, drew my attention to the " bone discovery " — I 

 feel assured that the bone breccia was washed into the cool- 

 ing joints of an older sheet of basalt, and was subsequently 

 overlaid by another flow. 



Unfortunately the bones are so broken up that they are 

 of little service in determining the exact nature of the 

 animals to which they belonged. Mr. Eoblin, however, by 

 careful pulverization of some of the fragments of breccia, 

 among other undetermined matter, obtained a small well- 

 preserved tooth, which undoubtedly belonged to a marsupial 

 of the genus Hypsiprymnus, or Kangaroo Rat family. I 

 also succeeded in obtaining one or two bones of interest, 

 among which is the well-preserved incisor of a marsupial 

 allied to the existing Wombat. 



I have made enlarged drawings of the more imj^ortant 

 fragments, which probably at some future time may be 

 serviceable at least in correlating the existence of the same 

 animal elsewhere, even if of little value in determining its 

 exact specific rank. The bones obtained by the late Mr. 

 Morton AUport from the Geilston travertin are most probably 

 the remains of the same species. 



It would be interesting to make comj^arisons with the 

 collections referred to, but I fear they have not been 

 preserved. It will be remembered by some that Mr. Allport 

 and others at first inclined to the oj^inion that the fragments 

 of bones preserved at Geilston belonged to existing species, 

 but this opinion was formed at a time when the relative 

 position of the travertin beds was not very clearly understood. 

 It is probable that the bone remains could only be identified 

 with existing genera, and that there is not sufficient evidence 

 to declare specifically their exact nature. However, some of 

 the members present may be able to give us further 

 information regarding this matter. 



Before leaving the section at One Tree Point, it is desirable 

 to draw particular attention to the fault at d, fig. 1. It is 

 evident that by the fault d, the beds a and h have again 

 been thrown up, so that we have, in travelling towards 

 Kingston, a repetition of the section e to d. Between e, fig. 1, 

 and the northerly limit opposite Sandy Bay Point, c, fig. 2, 

 there is evidence that considerable denudation has taken 

 jjlace, and consequently we are unable to fix, with satisfaction, 

 the probable thickness of the stratified sands and clays at
