more copper than is now produced by all the rest of the world. But 

 if our future penny-pieces are to bear any proportion to the reduced 

 cost of the value of the metal, they must be made of the size of din- 

 ner-plates ! ! — Athenadum^ No. 1018, p. 476. 



16. A communication from Professor Schottlauer, of Munich, ac- 

 quaints us with particulars of a new invention for painting upon 

 walls, discovered by himself, conjointly with Herr Fuchs, Counsellor 

 of the Mines, to be called Stereochromy. Its peculiarities are stated 

 as follows : — Far greater ease in its manipulation than fresco. The 

 ground is not laid in patches, but by one single operation. 'J he colours-, 

 prepared in distilled rain-water, take such firm hold as not to be dis- 

 turbed or altered by any subsequent washings or shades, while the 

 process of painting may be carried on with any amount of intervals, 

 thus rendering a far richer finish possible than with fresco. After 

 the picture is finished, it is saturated with a fluid, which unites the 

 ground and the colour into a mass of the consistency of stone ; de- 

 siccations being thereby rendered impossible, 'i'he colours are of 

 greater strength and brightness than with fresco, — though without the 

 slightest glare or reflection as of oil. It resists all atmospheric in- 

 fluences, — humidity, evaporation, &c. A test no less extreme than the 

 burning of alcohol, has been applied to it, without the slightest 

 change or deterioration. — AthentBum, No. 980, p. 820.
