INVESTIGATION OF JAPANESE LAQUOR. 261 



Now I prepared the silver salt of this substance, and 

 obtained i8'5 per cent, silver, the formula from which 

 does not correspond at all with the above ; and therefore 

 silver salt seems to give no help as to the formula for this 

 acid. 



As such was the case, I took alcoholic extract of 

 original laquor and precipitated it with acetate of lead, 

 and, after thoroughly washing, dried it at loo''. The lead 

 was estimated as before, and then subjected to organic 

 combustion. 



As I had but limited time, only the following two results 

 were experimentally obtained : — 



I. II. Mean. 



Carbon 4-9'84 5i"o6 50'45 



Hydrogen 581 560 570S 



Oxygen A-0'i° 39'^4 40"07 



PbO 3-50 405 3775 



lOO'O 



Roughly, when a formula is calculated from the above 

 analysis, substituting (HO)i for PbOj, we have very nearly 

 C10H50O1. 



In concluding my paper, I must say that I do not 

 satisfy myself at all with the analysis, inasmuch as the 

 two different salts do not agree. But I thought it might 

 be interesting to some of you from the fact that, as far 

 as I am aware of, this is the first analysis of the kind 

 attempted.
