ASS Proceedings 
Light-houses, by Sir D. Brewster, presented by Adam Jackson, Esq.; a 
Treatise on the Artificial Production of Fish, presented by Dr. Moore, of 
New Norfolk. 
Dr. Moore placed before the meeting, for examination, specimens of 
Gold-dust brought by him from Fingal, where he saw it washed from the 
soil: it had the rough, nuggetty appearance characteristic of the gold 
hitherto obtained there. Dr. Moore presented specimens of indurated 
bluish-gray slate, thickly studded with cubes of iron pyrites, from the same 
locality. 
Mr. H. Hull presented a small nugget of Gold from Fingal, weighing 
18 grains. 
Mr. Milligan submitted an assay of Tasmanian Gold-dust made by 
Samuel Thomas Abell and Co., of London, through the kindness of W. W. 
Saunders, Esq., of Lloyd’s, which gives—

Representing therefore a fineness of 22 carats 34 grains; and after deducting 
loss in melting, and expences of melting, assaying, and brokerage, equal 
to a net value of 79s., or 798. 3d. per ounce. 
The Secretary also submitted for inspection a massive nugget of gold 
from Mount Korong, Victoria,—weight 44 oz. 
Fragments of quartz containing gold and pyrites of iron with gold 
interspersed, broken from a solid mass of auriferous quartz traversing the 
slate in the vicimty of “ Specimen Hill” and “ Sailors’ Gulley,” Victoria, 
were received from Mr. John Amos, who, with his brother and another 
partner, successfully worked the gold in situ for ten weeks, quarrying, 
plasting, and incinerating the quartz from which the precious metal was 
afterwards easily picked out. 
Fragments of compact white quartz containing gold disseminated in 
grains, and deposited in drusy cavities and mixed with iron pyrites, 
together with specimens of drift gold arrested in an arenaceous conglo- 
merate over soft clay slate, were received from Mr. William Robertson, of 
Macquarie-strect. 
Mr. John Abbott presented the skin of a nankin or ash-coloured duck 
recently shot at Muddy Plains, considered by some members an Albino 
variety, while others thought it a young specimen of Gould’s Leptotarsis 
Rytoni, which it resembles a good deal in the form and colour of the head, 
neck, legs, and feet, but which had hitherto been only met with at the 
north of Australia. 
Mr. Abbott, Dr. Agnew, and Mr. Propsting remarked on the unprece-

and throughout the length and breadth of Tasmania during the last few
