» The results of the analyses of lumbang oil quoted by Wilcox 
and Thompson and of those of Aguilar vary somewhat, but they 
all have the same characteristics of high iodine and saponifica- 
tion values. : 
The constants of Philippine lumbang oil are quite similar to 
those of tung and linseed oils. This is shown by the work of 
Richmond and Rosario, the results of which are recorded in 
Table 18. In view of this similarity, it is not surprising that 
lumbang oil has properties very similar to those of tung and 
linseed oils and that it may be used for like purposes.
