 conducted with this milk, having in view its utilisation as a waterproofing 

 or as a paint for ships. The subject is alluded to because sufficient

 _ morally believed to be a native of Africa, but has been for many years com- 

 pletely naturalised in India, especially in the drier tracts of Bengal, the Deccan, 

 South India and Ceylon. Heyne (Tracts, Hist, and Stat. Ind., 1814, 243) discusses 

 fully the possibility of utilising the milk of this and other Euphorbias. Drs. 

 Riddle, Cheek and Falconer devoted much time and attention to the self -same 

 subject about 1850. It was observed that after boiling, the milk of this species 

 becomes brittle, though whilst warm it is ductile and elastic. Giberne 

 (Ind. For., 1899, xxv., 84-5) has urged the desirability of the milk of this and Possible Useful 

 other species of Kinthorbitt being put to some useful purpose. He found that 

 nitric acid caused the separation of the rubber. Mixed with mud the milk is 

 employed in North Arcot in the construction of the flat roofs of houses. It is, in 

 Ganjam, said to be used to intoxicate and poison crows : for this purpose a little 

 mixed with boiled rice and given to these birds. The acrid juice is in India 

 nerally, well known as a purgative and counter-irritant (especially in the Purgative.

 very acrid, some say poisonous, hence the name Blinding Tree or arbor ex-

 view to ascertaining its value as a rubber. The TIMBER is useful for general Timber, 

 upentry purposes and for match-making. [Cf. Pharmacog. Ind., iii., 1893,
