PHARMACEUTICAL NOTICES. 
Dissolve the Sulphate of Iron in four pints of the water, 
and add three ounces of honey to the solution. Dissolve the 
Carbonate of Soda in the same quantity of water, with a simi- 
lar quantity of honey, subsequently added. Mix the solu- 
tions thoroughly in a bottle just capable of holding the mix- 
ture, stop it closely, and allow it to remain 24 hours, until the 
precipitate subsides. Draw off the supernatant fluid with a 
syphon, and again fill the vessel with honeyed water, in the 
same proportion as before, mix thoroughly, and again draw off. 
Repeat this operation a third time, that all the sul- 
phate of soda may be washed away, — then pour the precipi- 
tate upon a flannel cloth, suffer the liquid to drain off as 
much as possible, and subject what remains to gradual pres- 
sure, until as much water is removed as possible. Then place 
it in a suitable evaporating dish, add nine ounces of clarified 
honey, and mix them intimately. Having put the evaporat- 
ing vessel on a water bath, the temperature of which should 
be so regulated as to keep the mixture of honey and 
proto-carbonate at the temperature of 150 degrees, it should 
be stirred occasionally at first and frequently toward the last of 
the evaporation, until it acquires a pilular consistence. There 
is no difficulty in regulating the temperature of the water 
bath. By placing a lamp under the vessel which serves as 
the water bath, its flame may be so regulated as to keep the 
mixture at the constant temperature of 150 degrees, by plac- 
ing a thermometer in it, until that degree is attained, and then 
lowering the flame, if necessary, until the thermometer re- 
mains stationary. 
This preparation when made in winter, is generally too 
soft for summer use in the form of pills, without the addition 
of some dry substance to give it a firmer consistence. My 
friend EiiasDurand, of this city, has proposed the substitution 
of sugar, for a portion of the honey, which he assures me 
gives increased consistence to the mass. About 4^ ounces of 
sugar should be added in place of the same quantity of honey, 
in the above formula.
