 of alcohol which has not been changed -to acetic acid. 



The analyses show the results of the crude methods employed by the 

 natives throughout the Archipelago. It would appear that there is a 

 potential possibility of producing good vinegar from this material.

DISTRIBUTION AND HABITAT. 



The buri palm is one of a small genus consisting of about half a 

 dozen very closely related species, which includes the talipot palm of 

 Ceylon and the fan palm of India. " It is distributed from Bengal and 

 Ceylon to the Sunda Islands. The products are so much alike as to 

 be known by the same name, regardless of the species from which they 

 are derived. 



"Watt "^ states that since Eoxburgh views C. umhraculifera as the in- 

 tennediate form between C. taliera and C. elata, for industrial purposes 

 they may be regarded as but forms of one plant and it is impossible to 

 correlate the various properties assigned to them. 



Corypha umbraculifera L. has been considered to be the buri of the 

 Philippines, but Doctor Beccari has detemiined the Philippine material 

 sent to him as representing two or more species of the genus, and he 

 considers it doubtful if the true C. umbraculifera L. occurs in the Arch- 

 ipelago.
