 cylindrical. If we make a vertical section (see fig. 7), 

 great regularity of the cortical utricles will be apparent.

The utricles are very ti-ansparent ; the vessels that 

 occupy the centre of the root are shown in fig. 8. The

young beet soon gives out small I'adicles, which gene- 

 rally form near the vascular tissue, become conical, and 

 present in their centre el ongated utricles. Some of these 

 have a nucleus that possesses a luminous spot, these 

 seem to form one over the other. (See fig. 9.) These 

 small particles will come in communication with the 

 vessels in the centre of the mother-root and then pene- 

 trate the cortical parenchyma.
