"A new and effective method has
been introduced for protecting dyers'
vats against damp and fire. 1t con-
sists in grinding oxide OF zinc--not
sulphite of zinc white-with glue water
until it forms stiff paint, and with
this covering the wood, which latter
must be quite dry. After it has dried
two or three hours it is again painted

making the apices less likely to de-
velop organic disease.-Virginia Med

"A process of engraving on glass
and crystal by electricity has been
communicated to the French Academy

trated solution of nitrate of potash, and
put in connection with one of the poles
in the battery, and the design is traced
out with a fine platinum point con.
nected to the other pole. The results
are said to be of marvellous delicacy.
Experiments have been made on the
! preservation of wood placed in the
ground. Piece of oak sunk in the

of the tree. decayed in twelve years
/ while indentical pieces, coming from
the same tree, but inserted in the op
posite way, showed hardly any trac'
of decay in the same time. The phe

seem to augment considerably its dura
