A fictitious amber for manufacturing
purposes is prepared by melting pure
bleached shellac, and keeping it over
| the fire until il runs clear, with care TO
prevent burning. 1t may be poured
into moulds of the size of pieces re-
quired. The operation requires con-
siderable management. The darkest
and hardest pieces of gum copal arr
also substituted for amber. The copai
may be fused with the shellac.
A modification of the American au-
diphone, which has proved OF great
service to the deaf and dumb, has been
described by NJ. Caladon before the
French Academy of Sciences. Instead
of hard rubber, a peculiar kind OF paste
board is used for the disk, and there
are no cords needed to regulate the tel

line have not very often been success
full. A native of the province of Ben
gal has, however, trained several Of
them to work the cords 10y which the
punka, OF ve%ntilating fan of India, is
moved. They perform their task to
perfection, and, thanks to their activi-
ty, keep the punkas in continuous mo-
ton, maintaining a constant agreeable
movement of air all through the room.
Says the Scientific american: There
appears to be quite 4 horror in the
West in connection with the manufac-
ture of glucose from corn. A large
number Of factories are being set up;
one at Chicago, it is said, will have Il
capacity of 10000 bnshels h day. A
bushel of corn produces 80 pounds of
glucos grape sugar or three gallons
Of syrup. The sugar costs two cents i;
