bones were obtained from the margin of a lake near Lake Colac, 
Port Phillip.

Mr. R. C. Gunn exhibited specimens of Pilularia found in a 
marshy spot at Penquite. It possessed certain peculiarities which 
may probably separate it from the Pilularia globulifera of 
Europe. Mr. Gunn took occasion to observe how many aquatic 
and marsh plants were common to Europe and Tasmania, and he 
specified amongst others,— 
Arundo Phragmitis 
Calystegia sepium 
Caulinia Oceanica 
Isaetes lacustris ? 
,, setacea ? 
Lemna gibba 
,, trisulca 
Lythrum salicaria 
,, hyssopifolium 
Potamogeton natans 
,, gramineum 
Prunella vulgaris 
Ruppia maritima 
Typha angustifolia 
Valisneria spiralis 
Zostera marina, 
Besides numerous Junceee , Cyperacea, and Graminece ; none 
of which had been introduced by man. 
Read a letter from James Gibson, Esq., of Circular Head, 
wherein that gentleman states, that a pair of domesticated Emus 
had, in the park at that place, reared six young ones during the 
past spring. The female made her nest early in October, laid 
eight eggs, and the period of incubation was exactly six weeks. 
The Emus were originally brought from Port Phillip.
