EXERCISE 19. To DETERMINE PER CENT OF HULLS IN OATS 



Weigh out and examine carefully two lots of 100 oat kernels from a well- 

 mixed sample of oats, and record the weights below. Separate the hulls of 

 the kernels in each lot by means of a scalpel or penknife, and weigh them 

 carefully; also any impurities that may be present. Calculate the percentage 

 of this weight to that of the whole oats. 



What is an average figure for per cent of hulls in heavy, medium, and 

 light oats?
