We purchased a new
batch because we are now at a higher level because this is during the same rice,
In terms of tolerance, assuming 1500D
per minute per quart of the highest result we
have obtained to date, is about one per cent,
And as of the fall of 1955, the laet sampling
period, we were running about 5D/M per quart
which 18 about 1/300 of tolerance,
