In the President's address to the members of the Microscopical 

 Society of Victoria, I observe a notice of the large species of 

 Vallisneria, common in our waters, and highly advantageous for 

 microscopical observation. This plant was collected and culti- 

 vated many years ago for the same purpose by Mr. Alfred 

 Roberts, M.R.C.S., in Sydney. 



A paper on Microscopical Rock Sections was contributed to 

 the same society by A. W. Howitt, Esq., of Gippsland. One on 

 Iron in Vegetable Tissues, by the President (Dr. Ralph). On 

 Desmids and Confervoids, by C. W. Mapleston, Esq., of Tarna- 

 galla. On Infusoria, Rotatoria, and Entomostraca, by the same 

 author. The President drew attention to the best methods of 

 working with the microscope, and the preliminary knowledge 

 requisite to make the use of that instrument both interesting and 

 useful. 



The papers read before the Royal Society of Victoria are 

 chiefly, as usual, upon Astronomy and Physics. But the Rev. J. 

 E. Tenison- Woods supplied an account of various new marine 

 Mollusca, and Mr. Etheridge an article upon Palaeozoic Actinology 

 in Australia. 



The following Papers, more or less bearing upon the Natural 

 History of Australia, have appeared in the Proceedings of 

 various learned Societies, viz. : — 



The Linnean Society, London. 



Mr. R Bowdler Sharpe on the Birds of New Guinea, collected 

 by Dr. James. Part 2.
