this mode of instruction, and of the advantage which it affords 
to families. The methods practised in foreign countries have 
not been exactly followed in Geneva, but modified to suit our 
national habits and manners. 
Mutual instruction has been introduced with much success 
in music; and marches, with religious, moral, and patriotic 
hymns, calculated to impress noble and pious sentiments, 
have been admitted as a recreation. We may well felicitate 
ourselves on the effects which result from these foundations 
for the moral instruction of children. An increased degree 
of obedience, order, neatness, and decency of language is al- 
ready observable. A generation educated upon principles 
which are based upon religion and morality, cannot fail to 
supply the country with good citizens. 
The schools of the new territory, placed under the direc- 
tion of the committee of public instruction, have continued 
to prosper; their number amounts to 18, comprising that of 
Puplinge, recently founded, and they present altogether the 
interesting assemblage of 855 pupils. The method of mutual 
instruction established in all these schools (that of Aire le 
Ville excepted, where the number of scholars is very limited,) 
obtains a success which we had scarcely dared to hope for. 
The various regents of these schools unite at Geneva, to at- 
tend a course on the method itself, given by a skilful teacher, 
who has studied it with care, and who applies it with great 
success. The effect of this will be to excite emulation among 
the regents, and uniformity in the schools, which will much 
facilitate the management of them. Prizes have been distri- 
buted in the present as well as the last year, and the happy 
effects of them are every day manifest.—Revue Encyc. Nov.

11. Compound of various Metals.—M. Dittmer has shown 
in the Hanoverian Magazine that the following mixture, com- 
pounded by the privy counsellor Doctor Hermstadt, may be 
substituted for gold, not only with respect to colour, but also 
to specific gravity, density, and ductility :—16 loth (less than 
8 French ounces) of virgin platina, 7 loth of copper, and 1 
loth of zinc, equally pure: place these metals together in 
a crucible, cover them with powdered charcoal, and melt 
fhem completely into a single mass.—Rev. Encyc. Sept. 1825-
