Papers. — "A Bnef Note on the Occurrence of a Raised 

 Beach on Hindmarsh Island, South Australia," by Herbert 

 Basedow. Tlie position of the beach the subject of this 

 paper is situated on the main track on HindmarsK Island, 

 about five miles from the Goolwa Ferry, near the mill, and 

 consists of an imbedded, softish, calcareous sandstone capped 

 by a thin layer of travertine and loose black soil, and is prac- 

 tically level. Tlie sandstone, though extremely rich in mol- 

 luscan remains in good preservation, yet lacks much variety 

 of species. Tlie most abundant are those laid on the table 

 and mentioned above, and are species now inhabiting the 

 neighboring seas. In places the sandstone gives way to a 

 barren, rather fine-grained, sandrock, weathering conspicuously 

 along the borders of the Island into shallow caves, with 

 stalactitic protuberances hanging from their roofs, produced 

 by the water carrying and depositing carbonate of lime round 

 the roots of the present vegetation, which obviously form 

 ready watercourses. This lime hardening round the roots 

 forms a cement that resists the disintegrating action of the 

 atmosphere better than the suri'ounding rock, and thus the
