Mr. R. C. Gunn exhibited specimens of the Algce of Tasmania, 
recently described by W. H. Harvey, Esq., in the London 
Journal of Botany.

attention to obtaining specimens of Heterocladia of Decaisne , 
which exists in Van Diemen's Land;—as also all specimens of 
Caulerpa . 
Mr. C. S. Henty drew attention to the very great quantity of 
sea weed which during a vast number of years has been washed 
up on the beach near West Head, Tamar. The sea weed has 
decomposed, forming beds of rich manure of considerable 
thickness hitherto neglected. 
Mr. Gunn exhibited specimens of Iron Glance, obtained by 
Joseph Milligan, Esq., from near the Housetop Tier, Hampshire 
Hills—being the only locality known in the Island. This mineral 
was used by the Aborigines of Tasmania for the purpose of 
colouring themselves, and from its scarcity much valued by them.
