7. Process forcharging water with iron.—If we form a pile 
with a few pieces of silver and iron plates, placed alternately, 
and immerse this pile in water, the fluid will soon acquire a 
yellowish tint, and in 24 hours the oxide of iron will appear 
in abundance: If the ferruginated water be withdrawn, and 
the vessel be filled every day with fresh water, we shall have 
a kind of artificial mineral spring.*——Payen. Bul. Un. 1824. 
8. Reduction of sulphurous acid.—M. Dobereiner observ- 
ed that alcohol, saturated with sulphurous acid, dissolved 
more iodine, than if it were pure. The liquid containing 
these two substances, exposed to the rays of the sun, deposit- 
ed, to his great astonishment, crystals of sulphur.—Bul. Un.

9. Russian Drinks —The common drinks in Russia are 
the Kwass, and the Meth or Kisslichi. To prepare the 
Kwass, they take a quantity of rye, and having soaked about 
ae part of it, they spread it thinly on boards or plates,

to sprinkle it now and then with ater. When sufii- 
viently germinated, they mix it with the rest of the rye, pre- 
viously ground, and add to the mass a quantity of warm or 
tepid water. The vessel is then put into an oven, immedi- 
ately after the bread is drawn, or exposed to a similar tempe- 
rature, and by degrees more water is added to the paste, 
Stirring it on every addition. After a time of repose, and 
when the liquid has become a little clean, it is put into a keg
