Previous Notices. 

 In 1864, during the absence from the colony of Mr. Sehvyn 

 who was visiting England on leave, the duties of Director of the 

 Geological Survey devolved on Mr. Aplin, the senior field geolo- 

 gist, and yielding to the public demand for more rapid surveys than 

 were being executed in the careful quarter-sheet work inaugurated 

 by his chief, he instructed Messrs. Daintree and Wilkinson, 

 who had just completed their work in the neighbourhood of 

 Ballan and Bacchus Marsh, to examine and report on the Cape 

 Otway District. The only visit hitherto paid by any of the staff 

 to the district was one made by Mr. Selwyn in 1858, when he 

 examined the coast-line as far as Apollo Bay (1, p. 11). Before 

 arrangments could be completed Mr. Daintree finally quitted 

 Victoria for Queensland, and Mr. Wilkinson was placed in 

 charge of the party, with Mr. R. A. F. Murray as assistant 

 (2, p. 11). Wilkinson sent in a preliminary report (3 and 4) and 

 then a more detailed one (5) accompanied by a section and map 

 (6). Duncan reprinted (7) that part of the detailed report 

 which dealt with what were termed the Miocene beds by 

 Wilkinson, reproducing a part of the section but omitting some of 

 the explanations and thus misleading Messrs. Tate and Dennant 

 who did not consult Wilkinson's original reports (12, p. 115). In 

 1873 Mr. F. M. Krause partially surveyed the country to the 

 east of Cape Otway but does not seem to have gone further west
