To determine the foregoing proportions of grain, etc., I took from a small bundle those 

 heads and straw which remained perfect, a certain number, and shelled the grain, and 

 weighed each part by itself. This method of determining the proportions of grain, chaff 

 and straw, has been found as correct, if not more so, as weighing large quantities in the 

 usual way. Due care must, of course, be taken to avoid losses in separating the grain.
