TEREBINTHINA ARGENTORATENSIS. 615 



States.' Dming a recent scarcity (1872-73) a sort of balsam from 

 Oregon Las been substituted in the American market for true Canada 

 balsam.^ 



Uses— The medicinal properties of Canada balsam resemble tliose of 

 copaiba and other terebinthinous oleo-resins, yet it is now rarely em- 

 ployed as a remedy. The balsam is much valued for mounting objects 

 for the microscope, as it remains constantly transparent and uncrystal- 

 Ilne. It is also used for makino- varnish.
