168 AMOUNT OE ALCOHOL IN 



containing 19 per cent, alcohol is found to be, 0*9999, 

 0-9984, 0-9971 0-9970 0-9966 0-9961. 



The same holds good in respect to other wines. 



The quantity of alcohol, for example, in the Rhine 

 wines, varies only between 9^ and 11-g- per cent., 

 whilst their densities range from 9934 to 0'9960. 

 But among such Rhine wines as give 11 per cent, 

 alcohol, we find the specific gravity 0'9953 0'9948 

 0-9940 0-9939 0-9934. It cannot be otherwise. 



The specific gravity of wine does not depend en- 

 tirely upon the alcoholic contents, but is more or less 

 affected by the non- volatile constituents. 



I subjoin various analyses of the alcoholic contents 

 of wine, with which other determinations are occa- 

 sionally given these we shall understand better by- 

 and-by, but in order to avoid repetition, I was obliged 

 to put them together here. 



Some of these numbers are inaccurate, more par- 

 ticularly because they have been obtained by means of 

 an inaccurate method. In order to make my summary 

 as complete as possible, I have selected sueh as are 

 most generally known.
