mydriatic, and is used externally in 10% solution; 

 in the eye, 1 to 2%; and injected in 1 to 4%. May 

 be boiled not to exceed 5 minutes without being 

 decomposed. 



ANESTHESIN is non-toxic, does not penetrate mu- 

 cous membranes, and is too insoluble for hypo- 

 dermic injection. Its action is prolonged, and it 

 may be used internally in gastralgia, ulcer, and 

 cancer of the stomach for the relief of pain. Used 

 in rhinology and laryngology largely. Dose: 5 to

 in ointments. 



BETA-EUCAINE LACTATE is more soluble than the

 added, which prolongs the anesthesia. For infil-
