Bogus Meerschaum.

The mineral meerschaum Is well
known to be a hydrated silicate OF mag
nesia, with two equivalents OF water.

I mines and separ holders. A strange an

I NAV be substituted for the subnitrate OF
blsmuth in cboleraic diseases. Deposits

founded simply upon the double deeon-
nOsition Of soluble alkallde sllieabes oy
animate OF magnesia. One pound aNoH-
dupois Of suiphate OF mAgnesla Is us
solved in about a quart OF water. Two
0usrtz of a solution OF soluble s~ilicate, OF

grees Fahrenheit. The product is
a gelatinous Preeipit9tei when Is
RonE washed, first with boiling,
fbe1 with cold water, until all alkaline
sulpbate IS removed, then poured into a
stone or zinc trough and dried at a tenn
perafure of not 0ver 100 fahrenheit.
The mass thus produced is compact, fra

-ebsum. and is susceptible OF being man.

wsv as the latter. For some years NJ.
Wagner has obtained good results by a
different method. He incorporates with
one part OF casino ~ six parts Of caleined
maenesia, and one part of oxyde Of zinc.
Upon drying this mixture there results a
material of a lustrOus whitenessl very
bsrd, susceptible of being cut and pol
ished, and which perfectly stimulates the
natural meerschaum.
