NOTES AND EXHIBITS. 543 



Mr. Palmer showed a stone-axe of a remarkable character, from 

 Lawson, but the circumstances under which it came into notice 

 were not such as to preclude the possibility of its being of non- 

 Australian manufacture. 



Mr. Greig Smith exhibited a series of thirty-five photo- 

 micrographs of Bacteria from Sydney water, in illustration of a 

 paper read at last meeting. 



The Superintendent of the Botanical Gardens, on behalf of Mr. 

 Maiden, exhibited two well grown pot-plants in flower, viz., 

 JSchmea Maricv-regince, Wendl., (N. O. Bromeliacea?) from Costa 

 Rica, and Gypripedium hirstctissimum, Lindl., from Java. 



Mr. Fletcher invited the attention of members to specimens of 

 the two forms of the common Pittosporum (P. undulatum, And.) as 

 usually met with about Sydney — namely, the form with rudi- 

 mentary stamens which fruits abundantly, and that with perfect 

 stamens and, as far as early appearances go, a satisfactory pistil 

 and a viscid stigma, but which sets no fruit. As the Pittosporums 

 are just now coming into bloom, a request was made for evidence 

 of any intermediate condition, if still to be met with; or of the 

 occurrence of the two kinds of flowers on the same tree.
