;uid yield of fruit, and the season of flowering and ripening. Extensive tests 

 liave been made of numerous varieties of apples for cider making. The results 

 indicate that a particular variety yields the same type of cider regardless of the 

 fource of the apples. Very few varieties are believed to possess all the charac- 

 teristics necessary for the production of first-class cider. Experiments in blend- 

 ing were also conducted. 



On the cause of the production of aldehydes in wine and the quantity 

 which is present in certain wines of Tuscany, X. 1'asseri.\i (Sta.z. tSpcr. Af/r. 

 luil., .J9 (lOOd). yo. 3, 1)1). JJI-240). — Aldehydes are considered a normal product 

 of alcoholic fermentation. They are produced by aerobic ferments rather than 

 anaerobic. The amount of aldehydes in wine is increased by the treatment of 

 the must with sulphites. The presence of oxydase derived from Botryiis 

 ciiierca is not believed to be a cause of the formation of aldehydes. 



In the wines of Tuscany the aldehyde content varied from 1 to CO mg. per 

 liter. Wines with a high alcoholic content contained usually the largest amount 

 of aldehydes and white wines contained more than the red.
