CHEMISTRY OF A HENS Etc.,.
Within the shell the animal portion
of the egg is found, which consists
Of viscous, colorless liquid called
albumen, or the White, and a yell
low, globular mass called the vitel-
lus or y0lk. The white of the egg
consists of two parts, each Of which
is enveloped in distinct membranes.
The outer bag of albumen, next the
shell is quite thin, watery body,
while the next, which invests the
yolk, is heavy and thick.
But few housekeepers who break
eggs ever distinguish between the
tho h'tSs, or know of their exis-
tence even. Each has It's appropri-
ate office to fulfil during the pro-
gress of incubation or Matching, and
one acts, in the mysterious process,
as important part as the other. Ii
we remove this glairy fluid from the
shell and place it in glass, and
plunge into it strip Of redeemed lit
mus paper, blue tinge is immedi-
ately produced, which indicates the
presence Of an alkai. The alkali is
soda in free condition, and its pre-
sence is of the highest consequence,
for without it the liquid would be
ine0L1ble.
A portion of the white Of egg wherr
diluted with water, and few drops Of
vinegar or acetic acid added to it,
undergoes rapid change. The liFr
uid becomes cloudy and foculent,
and small bits of shreddy matter fall
to the bottom of the vessel. This is
pure albumen, made so by removing
the soda held in combination by the:
use of the acid. A pinch Of soda
added to the solid precipitate redls-
solves it, and it is again liquid.
There IS another way by which
the albumen is rendered solid, and
that is by the application of heat.
Eggs placed in boiling hot water
pass from the soluble to the insolu~
BILE state quite rapidly, or in other
words, tbs albumen both of the
white and the yolk becomes ''coagU-
lated"
No contrast can be greater than
that between a boiled and an unboiled
egg. Not only is it changed ply
sically, but there is a change in
chemical properties, and yet no che
mist can tell in what the change con-
sists. 1t is true that water extracts
little alkali, and trace of sulphide
Of sodium, but the abstraction Of
these bodies is hardly sufficient to
account for the change in question.

BEET SUGAR IN WISCONSIN.
Mr.. Weferling, superintendent Of
the Black hawk Beet Sugar Manu-
featuring Company, reports last sea-.
sons operations to the Wisconsin
State Agricultural Society. 134,400
pounds Of sugar-pulverized, granu-
lated and loaf-were made. Two
hundred and thirty acres were plant
ed to buds, producing, on account Of
the dry season, only about four and
one half tons to the acre. The fac
tory runs nearly two months at a
daily cost of $500, while the product
was about $402, leaving a margin
of $500 per day. Not very prof.
liable showing to be sure, but as the
superintendent argues that as it costs
but trifle more to run large facto.
ry than a small one, there is nothing q
discouraging in the result. With a
good crop, and ample facilities for
manufacture, he has no doubt of the !
result. The stockholders Of the
company are 50 sanguine of ultimate
success that they have agreed to again o
furnish their proportionatc share Of
beets and wood to keep the factory
running another season.
