substances of its class, affording relief but not cure 

 in herpes zoster, ivy poisoning, and other lesions 

 relieved when protected from the air. In chronic 

 bronchitis, coughs, and genito-urinary diseases, it acts 

 as a terebinthinate and possesses no advantage over 

 others of the group, and indeed it is inferior to sev-

 acum officinale and G. sanctum. Official in the U. S., 

 resin and heart-wood in a number of other countries.

 While the creosote and guaiacol compounds, as well

 matter of fact they are nearly all synthetically built
