This mixture is too alcoholic to retain in solution the sulphate of magnesia, 
which, although first dissolved in the camphor julep, subsequently concretes into 
a crystalline mass,

Misce. Signa—Forty minims (by measure) in water twice a day

remains at the bottom cf the bottle as a dense white powder, not to be shaken 
up and poured into a minim measure.

Misce, Take a small teaspoonful in a wineglassful of water when 
required, and repeat the dose every two hours until the pain is 
relieved. 
The addition of the borax to the other ingredients occasions the separation of 
a sticky mass which adheres to the sides and bottom of the bottle in such a 
manner that the intended dose cannot possibly be administered, a difficulty 
which would be entirely obviated had the mixture been ordered in a dilute 
form.

Medicines prescribed according to such formulse as this and the preceding, 
are dangerous from their extreme concentration, and from the large quantity 
ordered rendering them liable to be mistaken for comparatively dilute mixtures 
taken in the dose of two or three tablespoonfuls.
