NON- VOLATILE CONSTITUENTS OF WINE. 289 



this wine freed from alcohol is 1*0805 (p. 167), which, 

 according to Balling, gives 19*6 extract. Muscat 

 Eivesaltes contains 24*5 per cent, extract (p. 282), 

 whilst the wine freed from alcohol is 1*0946 (p. 167), 

 which, according to Balling, gives nearly 23 per cent, 

 extract. We conclude, therefore, that Balling's esti- 

 mates are too low for large, and too high for small 

 quantities of extract.
