Fresh Water Algce of Victoria.

IV. at the last Industrial Exhibition, may be examined for 

 the ores of tin, and the granites of the Australian Alps and 

 Pyrenees for kaolin. 



I have thus briefly indicated some of the districts of the 

 colony, which are particularly worthy of investigation, and it 

 is certain that if they were properly examined, new and 

 important facts would be disclosed, valuable to the world of 

 science, and leading to the establishment of permanent 

 industries. 



The 25,000 square miles of sandstone and clayslates, inter- 

 sected nearly everywhere by metaliferous and mineral 

 lodes, are an expression of our wealth, and ought to content 

 us, and assure us of a permanent prosperity. But this vast 

 area must be explored, and it would be well for the colony 

 if this learned Society, having just concluded an enterprise 

 far surpassing in its magnitude and in its results anything 

 yet attempted by the Society in London, whose whole aim 

 is to extend geographical research, it would be well, in my 

 humble opinion, if this Society would now devote its ener- 

 gies to enquiries having immediate reference to the physical 

 structure of the colony. 



Art. XIX. — On the Fresh Water Algce of Victoria. By 

 Henry Watts, Esq., of WarrnambooL 



[Read 21st November, 1864.] 

 During my residence in this colony I have collected various 

 species of fresh-water algse and desmidiacese, and believing 

 at present there is no record of these plants having been 

 found in this colony, I am induced to present to the Royal 

 Society, a list with localities of such specimens as have 

 come under my observation :
