ANALYTICAL DATA ON THE SAMPLES TAKEN DURING THE PROGRESS 

 OF THE EXPERIMENT. 



When each vat was filled, gallized, and stirred a sample was taken 

 to represent the unfermented grape juice plus sugar water. From 

 observations made as the experiment progressed, and from the 

 analyses of the young wines as drawn and of the wines in each of the 

 casks when completed, it is conclusively shown that these samples of
