In Table 13 it will be noticed tliat the total mineral matter in 

 the bulb of the three specimens is very different. The bulbs of 

 Nos. 106 and 108, 'tis true, agree pretty closely in this parti- 

 cular; but the resemblance does not extend to No. 107. On the 

 other hand, in the leaf (Table 14) Nos. 107 and 108 resemble 

 each other, whilst 106 stands apart. In the bulb of Specimen 

 107 there is very little phosphoric acid ; in the leaf, on the con- 

 trary, there is a greater quantity than in the other specimen. 

 Weight for weight, the leaves are considerably richer in this im-
