Misce. Signa Forty minims (by measure) in water 

 twice a day after meals. 



Here again the liquids are insufficient to dissolve the alkaline 

 salt, which remains at the bottom of 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 wineglass 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 diluted 

 form.
