Bulletin 167 



Twenty-eight samples were deficient in total ash in amounts 

 varying from 0.02 to 0.18%. The deficiencies mainly occur 

 among samples in the control groups. Eleven samples were 

 low in insoluble ash, but the shortages were very slight, varying 

 from 0.01 to 0.03%, the latter figure occurring but once. There 

 were 12 deficiencies in malic acid values, many of them being very 

 small and ranging from 0.01 to 0.16%. 



Inquiring still farther into these deficiencies, it will be 

 found that in several cases but a single item of the three-fold 

 standard is affected. Eliminating the groups exhibiting no de- 

 partures from standard, the following table appears.

Assuming that standard maintenance in two instances and 

 a very close approach thereto in the third would suffice to pass 

 a sample, a large share of the samples heretofore listed as 

 below standard are eliminated and attention is fixed upon the 1 1 

 lots, listed in the last four columns, four of which are below in 

 both total and insoluble ash, one low in both total ash and malic 

 arid value, while six are low in all three items.
