NOTES AND EXHIBITS. 



Rev. Dr. Woolls sent for exhibition specimens of lerp or manna 

 — some still in situ on the branchlets — from Eucalyptus pulveru- 

 lenta, Sims, found at Buckley's Crossing ; manna is frequently- 

 met with on E. viminalis, Labill., (formerly called E. mannifera), 

 and a few other species, and occasionally on E. punctata, DC, 

 but this is the first instance of its occurrence on E. pulverulenta 

 known to Dr. Woolls. 



Also, portion of an unusually fine specimen of a lichen, Usnea 

 articulata, Ach., several feet long, recently brought from New 

 England by Mr. C. S. Wilkinson, F.G.S. ; and a specimen of 

 another remarkable lichen, Cladonia retipora, Flcerke, a species 

 common to Australia, Tasmania, and New Zealand. 



Rev. J. Milne Curran exhibited a stalactite of metallic copper, 

 showing obscure crystalline facets. The mass, which weighs 7^1bs., 

 was found at Cobar in a cavity in carbonate of lime, hanging by 

 a single thread of metallic copper. The copper was evidently 

 deposited from solution by some inexplicable reactions. 



Mr. Etheridge exhibited a very fine series of Aboriginal Toma- 

 hawks and Axes in illustration of his Paper. 



Mr. Maiden sent for exhibition a quantity of seeds of the sugar- 

 cane from Barbadoes, with the intimation that he would be glad 

 to furnish growers in the Northern River Districts with samples 

 for experimental cultivation. 



Mr. Eroggatt exhibited some living beetles (Axionichus insignis, 

 Pascoe, fam. Curculionidae), which afford a good example of 

 protective coloration. They were found a few days since at 

 Wellington, N.S.W., on the trunks oi Kurrajong trees (Sterculia), 

 the bark of which they resemble so closely in tint and general 

 appearance that it was quite by accident he first recognised their 

 true character.
