in the axil of c', and the structure of the shoot is now complete 

 for the ensuing season. 



From the description previously given of the disintegration 

 of the bulb, it will be seen that the two last leaves (e) and 

 {e'), alone are responsible for the formation of the following 

 year's bulbs, and since these two leaves are practically con- 

 temporaneous in origin, and of the same stage of development.

A few points in comparison of the garlic with other bulbous 

 plants may now be noted. The germination of the seed and 

 origin of the bulb is probably typical of a large number of other 

 monocotyledonous plants, and consequently, owing to the com- 

 monness of the species and regular production of fertile seed, 

 it will be found to be a convenient plant in which to study 

 this type of germination. The wild hyacinth [S cilia festalis) 

 germinates in almost precisely the same manner, and is equally 

 abundant, but other wild bulbous plants, e.g., snowdrop and
