The analytical results are given in Table XI. The analyses 
of the still charge and of the residue have been rejected as some- 
what untrustworthy.

As was to be expected these results differ in no essential 
respect from those obtained in previous distillations. 
Rough approximations of the efficiencies of the two distilleries 
have been made indicating the failure to obtain in the dis- 
tillate from 10 to 20 per cent of the alcohol present in the tuba. 
The loss during distillation owing to leakage and evaporation 
is slight; practically the entire amount is due to incomplete 
distillation. The residue at these distilleries normally appears 
to contain between 0.1 per cent and 0.4 per cent of alcohol. 
THE POTABILITY OF PHILIPPINE DISTILLED BEVERAGES. 
THE POT-STILL BEVERAGES. 
It is the generally accepted belief among the white residents 
of the Philippine Islands that the use of native distilled bever- 
ages is attended with very deleterious physiological effects, 
attributable to the presence of certain “poisonous” substances 
among which “fusel oil’? and wood (methyl) alcohol are often 
specified. 
It is hardly necessary to state that methyl alcohol does not 
occur in any distilled liquors of the Philippines or elsewhere, 
unless it has been added to the finished product in wilful adul- 
teration. None has ever been detected in any native beverage. 
It may be seen from the analyses given that “fusel oil,” a 
term applied to the alcohols higher in order than ethyl alcohol. 
is found in liquors of local manufacture in amounts which are 
notably smaller than in similar imported liquors of pot-still 
type. 
The average content of aldehydes (and also of furfurol) is 
by no means abnormal. 
In fact the only respect, so far as may be determined by 
chemical analysis, in which this class of distilled beverages may
