up oxygen from the air, and some of the substances connected! 

 with it, and with gutta percha have compositions and properties 

 very similar to those of the two constituents of Coorongite. 

 The formulae for these constituents ai"e readily derivable from 

 CioHjg by oxidation and hydration. However, for the present 

 the nature of Coorongite must still be considered an open 

 question, as much remains to be done in the furtlier chemical 

 investigation of its constituents.
