The presence of aromadendral was very marked, so much so that the odour 

 of the crude oils resembled those obtained from the true " Boxes," rather than 

 from the " Gums." Pinene was present in some quantity, but phellandrene 

 was absent. 



Material was obtained from the following localities in New South Wales : 

 Colo Vale, in July, 1900; Rylstone, in August, 1897, and Barber's Creek, in 

 July, 1898. The oils from these were very similar, and all gave practically 

 the same results. When tabulated it can be seen how well they agree in 

 general characters, although extending over a period of three years, and from 

 three different localities : 



The solubility ranged from 7 volumes 70 per cent, alcohol to 2 volumes 

 80 per cent, alcohol, and saponification number from 10-9 to n-6. 



This variety of E. punctata is apparently a tree not far removed, chemically, 

 from some of the typical " Boxes " ; other evidences also go to show the close 

 relationship existing between the " Gums " and the " Boxes." 



That alcoholic bodies were present in some quantity is indicated by the 

 results after acetylation of these mixed oils. The saponification number was 

 then 1 57-6.
