472 Bulletin 167 



This treatment resulted in an increase in total ash for the 

 11 samples of 1.27%, averaging 0.115'/ for each sample, with 

 extremes from 0.02 to 0.21%. The insoluble ash was increased 

 0.62%, averaging 0.056^, with extremes from — 0.01 to +0.16%. 

 The soluble ash was increased 0.55%, averaging 0.05%, with 

 extremes from ■ — 0.04 to -j-0.16%. The standard is met as far as 

 the malic acid value is concerned in all but one sample (No. 108) 

 and even in this case the deficiency is slight. 



This procedure seems to make it clear that the failure of 

 several samples under discussion to meet standard require- 

 ments in certain particulars is not due to the influence of the 

 inoculating organism employed, but rather to the over-concen- 

 tration of the sample which, during the long period of sedi- 

 mentation, caused a larger amount of niter to form and to 

 settle out than would have formed and settled had the concen- 

 tration been less and nearer that of the eleven-pound gallon.
