Aquae are solutions of volatile substances in water. The volatile substance may

 cinnamon and 0.15 Gm. purified talc; gradually add 100 mils distilled water, contin- 

 uing the trituration. Filter and repeatedly refilter until filtrate is perfectly clear.

 fluous), A. Aurantii Florum (for making Syrupus Aurantii Florum), A. Aurantii 

 Florum Fortior (for making the preceding Aqua), A. Camphorae, A. Chloroformi, A. 

 Creosoti, A. Fceniculi, A. Rosae, A. Aromatici (a saturated aqueous solution of volatile 

 oils), A. Hamamelidis (a popular embrocation of doubtful value). 



SYRUPUS. 



Syrups are concentrated solutions of sugar in water or in aqueous liquids. They 

 may be made extemporaneously by adding a medicated liquid to the official Syrup. 

 Besides being a pleasant vehicle, Syrup is somewhat of a preservative of vegetable 

 compounds, and tends to retard chemical changes in some readily oxidizable substances.
