In 1906 the present writer crossed the Flinders Range 

 from Parachilna, westerly, to the eastern slopes border- 

 ing on the Lake Frome plains. The journey was done mostly 

 ■on foot. Publication of results was deferred with the hope 

 that opportunities might arise by which the geology of the 

 country could be still further investigated and descriptions 

 made more complete. As this is now unlikely, the present 

 notes are placed before the Society as a summary of the work 

 done at the date mentioned, incidental to defects which must 

 necessarily accompany observations made on a single traverse 

 of the region. (1) 



(1) Some preliminary notes of this journey were included in a 

 paper by the author, read at the Adelaide meeting of the Aus. 

 Assoc, for Adv. of Science (1907), on ''A General Description of 

 the Cambrian Series of South Australia," pp. 414-422.
