f egg. Equal
quantities of beef tea and whey are good for delicate infants.

2455. Beverage for Hot Weather.

The yolk of eggs beaten up, lump sugar (to taste), Rhenish wine or
not, citric acid powdered, or tartaric acid (small quantity, exact
quantity soon found); one or two drops of essence of lemon on a lump
of sugar, to make it mix readily with the water; one quart of water.
This is really an excellent, agreeable, and, without the wine, an
inexpensive beverage.

2456. To Ascertain the State of the Lungs.

Persons desirous of ascertaining the true state of their lungs should
draw in as much breath as they conveniently can, they are then to
count as far as they are able, in a slow and audible voice, without
drawing in more breath. The number of seconds they can continue
counting must be carefully observed; in cases of consumption the time
does not exceed ten, and is frequently less than six seconds; in
pleurisy and pneumonia it ranges from nine to four seconds. When the
lungs are in a sound condition, the time will range as high as from
twenty to thirty-five seconds.

2457. To Avoid Catching Cold.

Accustom yourself to the use of sponging with cold water every morning
on first getting out of bed. It should be followed by a good deal of
rubbing with a wet towel. It has considerable effect in giving tone
to the skin, and maintaining a proper action in it, and thus proves a
safeguard to the injurious influence of cold and sudden changes of
temperature. Sir Astley Cooper said,

"The methods by which I have preserved my own health are
--temperance, early rising, and sponging the body every morning
with cold water, immediately after getting out of bed,--a practice
which I have adopted for thirty years without ever catching cold."

2458. How to Prepare Artificial Sea-Water.

In each gallon of river or rain water dissolve about six ounces of
sea-salt, either by stirring it or suspending it in the water in a
linen or muslin bag. It dissolves as readily in cold as in hot water.
Sea-salt is produced by evaporation of sea-water. Common salt is
sometimes supplied in place of it; but the genuine sea-salt,
manufactured by well-known firms, which can be procured of any grocer
or of most chemists, is specially prepared to enable persons to have a
salt-water bath
