ABSTRACT OF PROCEEDINGS. Exe. 
veins of a pinkish or salmon-coloured chalcedony, exhibiting a 
porcelain-like texture and broken surfaces. The veins of opal 
vary from 3's” to 4” or more in thickness, and in colour from the 
palest to the deepest apple-green. A fair proportion of the mineral 
is translucent, but much of it is clouded and opaque. The 
powdered mineral—selected fragments of the deepest colour— 
gave a strong nickel reaction. The veins of opal and associated 
chalcedonic veins have as yet been opened only for about eighteen 
inches from the surface. 
Some observations were made by Professor Liversidge. 
4. “Icebergs in the Southern Ocean, No. 2,” by H. C. Russet, 
B.A., C.M.G., F.R.S. 
This paper was prepared as a continuation of one read before 
the Royal Society, Sept. 4, 1895. It deals with the reports of 
icebergs seen since the end of July 1895. One hundred antl two 
ships have reported ice in the interval, nearly the whole of the ice 
So reported, was within the area enclosed between 40° and 86° 
east longitude and 40° to 62° south latitude; very few reports of 
ice outside that area have been received, It was shewn that the 
Thermopyle steamed for 1,000 miles amongst icebergs, and that 
the ocean was clear one hundred to one hundred and twenty miles 
north of this track. Some idea of the number of icebergs may be 
gathered from the fact that the officers of one ship counted 977 
bergs, and those of another ship 4,500. This and the previous 
paper cover a period of six years, and it was shewn that at times 
the icebergs come into, or leave the track of vessels in a few days; 
three instances in which there had been sudden disappearances 
were shown to be coincident in point of time with the advent in 
Australia and the ocean between the Cape and Australia of strong 
north to north-west winds.
