In the United States Daily Comiilar and Trade Reports (No, 

 3,437) the consul general at Calcutta reports on recent experi- 

 ments with milk from a plant abundant in the lower Himalayan 

 region, popularly described as a cactus, which yields what 

 strongly resembles gutta-percha and apparently possesses insulat- 

 ing qualities. It is believed in India that this plant, hitherto re- 

 garded as useless, will be found to have a considerable value. 

 Consul General Michael identifies the plant with what is described 

 in Watt's ^'Commercial Products of India" as Euphorbia Roy- 

 Icana (Boiss), though the cactus family in general is comprised 

 outside of the Euphorhiacccc. Watt wrote: "The milky sap of 

 this plant contains a large amount of gutta-percha."
