3 About the average percentage of nitrogen was found present in this sample. The nitrogen guarantee 

 is unusually high, describing a product 100 per cent pure nitrate of soda. A letter from the company 

 states that the correct guarantee should be 15 per cent nitrogen and that a mistake was made in giving 

 16.47 per cent as the minimum nitrogen guarantee. The product showed a commercial shortage of S3. 81 

 per ton on the basis of the higher guarantee, but was well above 15 per cent.
