 The stalk and main veins are negative only as regards the 

 central white portions . The outer layers contain chlorophyll . 



The so-called leaves — or what may more appropriately 

 be termed the heads — of the cauliflower, are positive, and 

 in order that they may receive charge the inner leaves fold 

 closely over them. These leaves in all probability have 

 their supply from the principal generators — ^the iron- 

 containing green outer leaves — and are therefore not entirely 

 dependent upon air as the vehicle of positive charge. 



A section through the " heads " is not without interest :
