EGGS FOR MEDICINAL USES.—In cases of poison- 
ing by salts of lead, mercury, copper and acids, adminis- 
tering the whites of eggs will render them harmless. The 
whites should be mixed with water and drunk. The 
albumen in the whites of the eggs is curdled by the poi- 
sons and renders.them inert for long enough a time to 
allow an emetic to act. The white of one egg will neu- 
tralize 4 grains of bichloride of mercury (corrosive sub- 
limate). 
The yolks of eggs, or even the white and yolks rubbed 
into the hair, make a most excellent stimulant and pre- 
vent the hair from falling out. Wash thoroughly in soft 
water after the eggs have been rubbed into the hair. 
The white of an egg is an excellent application to 
spread over a newly-made burn or scald, especially if the 
skin is broken. Several coatings should be applied. 
Mustard plasters if mixed with whites of eggs will not 
blister, yet will lose none of their efficiency. 
EGGS, METHOD OF PRESERVING.—There are 
several methods of preserving eggs, but the easiest and 
best one is known as the waterglass method. Waterglass 
is a thick, syrup-like fluid technically known as sodium 
silicate. To preserve eggs by this method boil 9 gallons 
of water and let it cool. Then add 1 gallon of water- 
glass and put the solution in a very clean vessel. Stone 
jars are best, but kegs or barrels which have been scalded 
until they are very clean and free from odors may be 
used. Put in the eggs from day to day as they are gath- 
ered, being very careful not to use any with cracked or 
dirty shells; see that every egg is perfectly fresh. If the 
eggs do not remain beneath the surface of the solution 
weight them down. Keep the vessel containing the eggs 
in a cool, dark place and do not disturb it more than nec-
