the jar lightly, and put it in a cool place for seven days, not 
forgetting to shake it well on each day. At the end of that time 
strain through muslin, when it will be found that the lemon juice 
has dissolved the eggshells. Add the sugar, and the rum; then 
bottle and cork it tightly. A wineglassful taken each morning 
before breakfast is the full dose, but at first it may be desirable 
to give only half this quantity. Again, for the cure of certain 
weaknesses in women, egg shells when. properly prepared are 
highly lauded in America. The shells are first broken up in 
vacuo, and then finely powdered in a mortar together with two- 
thirds of finely powdered sugar of milk. Dr. Edson tells of 
seventy consecutive cases treated thereby without a single 
failure. 
An “ egg foam ” which can be quickly prepared, as in America, 
is particularly suitable for the passing needs of invalids: Separate 
one egg, keeping the yolk unbroken in half the shell, whilst beating 
all the white to a stiff froth. Heap this latter in a dainty little 
bowl, or egg cup, and make a small well in the centre, into which 
drop the yolk. Then stand the whole in a saucepan containing 
a little boiling water, cover the saucepan, and cook for one 
minute. Serve in the bowl, with a tiny bit of butter, and a few 
grains of salt. The Germans call frothed white of egg “ snow.” 
This froth is sweetened and scalded in milk, so as to become set. 
It then serves as the solid part of a refection whereat the liquid 
part is milk (perhaps with egg yolk). Such a dish, to be eaten 
with a spoon, is very refreshing at any time of the year, but 
particularly in summer, if it be well cooled. It is also a very 
excellent form of nourishment for persons who are suffering from 
one or another throat affection, or who have undergone some 
operation in the mouth or throat, and who cannot chew, or pulp 
_ with the tongue, but can yet drink the soft custard. A raw egg 
is not so easily assimilated after being swallowed as is one lightly 
boiled. The natural principles thereof are albumin, vitellin, 
lecithin, and nuclein. The egg albumin differs from that contained 
in the liquid serum of our blood as to certain physical properties, 
though closely allied to this. If the white of a newly laid egg 
be applied to a sore burn, or scald, it will keep out the air, and 
will do much to relieve the pain. Powdered egg shells will subdue 
acid indigestion from fermenting sour food in the stomach. On 
_ the assumption that ten milligrammes of iron are required daily 
_ by the average human body, then seven and a half eggs would
