Fig. 11. — Portion of vascular net of quince, enveloping the flesh beneath 

 the skin, and sliowing the nieshea ( x 4). 



Fig. 12.— Portion of pliime-liUe branches, taken from a decaying quince in 

 water, and appearing like fine fluffy material when the stem is 

 removed. The innumerable branchlets extending to the skin are 

 -shown, and the deeper-lying branches from which they originate 

 (x3). 



Fig. 13.— Surface- view of skin of quince, showing the "window-cells," 

 about the same size as those of the pear. There are actual opening's 

 in the skin, round or polygonal (lenticels), and here and there, the 

 stomata still persist ( x 100). 



Fig. 14.— Cross-aection through skin and flesh, showing the thickened 

 outer walls(20/i,) of the oblong epidermal cells, and several layers of 

 subepidermal cells. The vascular bundles extend to the subepi- 

 dermal layer, and groups of " stone-cells " are shown, with the 

 elongated parenchyma-cells radiating from them ( x 100).
