Fossil Astdria. —I send you a drawing of the ^steria (fg. 19.), found at 

 Horsington, by the Rev. James Hooper, Rector of Stawell. It was taken 



from a stratum of cornbrash, and is a very perfect specimen. The sketch 

 and the figure is of the exact size of the original ; a is the stone in which it 

 is embedded, and b a section of a small bivalve shell. I am, Sir, &c. — 

 W. H., R. N. Yeovil, Aug. 21. 1828. 



Washing of Gold. — The art of washing gold was practised on the Rhine 

 from early antiquity up to 1824, when it ceased near Basil ; but a few men 

 continue to be employed in the environs of Lohr, as at Wittenweir there 

 are three, at Nonnenweir fourteen, &c. The gold is found in a coarse allu- 

 vial deposit, and sometimes forms a coating on the pebbles. The banks 

 containing the gold are usually about 100 paces in length. They are for 

 the most part on the margin of the river, and rarely in the islands. The 

 banks of pebbles containing the gold are covered with coarser pebbles and 

 vegetable earth. {Zeitschr^t fur Mineral., Juin, p. 533.)
