 the six varieties frcan ,033 to .050, potash from ,195 to .226, 

 nitrogen from .055 to .101. 



The percentage of phosphoric acid In the rind varied from 

 .029 to .043, potash from .240 to .350, nitrogen from .073 to 

 .108. The percentage of phosphoric acid In the seed varied 

 from .270 to ,360, potash from .430 to .460, and nitrogen from 

 .850 to 1.130. 



In every Instance the percentage of phosphoric acid, 

 potash and nitrogen was highest In the seed. The percentage 

 of phosphoric acid was In alm.ost every Instance higher In the 

 pulp than In the -^Ind, while the percentage of potash was 

 always higher In the rind than In the pulp. The percentage of 

 nitrogen was higher In the rind than In the pulp, except In 

 one variety, and even there the excess was very slight, .003 

 of one per cent. 



The total percentage of phosphoric acid, potash and nitro- 

 gen In all the parts of the fruit, pulp, rind and seed com- 

 bined were as follows^ 



The phosphoric ucld varied In the six varieties from .040 

 per cent to ,056 per cent, the potash from .2L3 per cent to 

 .251 per cent, and the nitrogen from .085 per cent to ,119 

 per cent. The average percentages In the six varieties were 

 as fbllows : .050 per cent phosphoric acid, ,237 per cent pot- 

 ash and .110 per cent nitrogen. 



To make practical application of the above analyses we 

 will assume that the average weight of a box of pomelos Is 80 

 pounds and find the amounts of the three Important plant
