Cross sections of the specimens were examined by electron microscope and measured the diameter of deposited particles of silver and its number in definite area of each layer (I+P, S_1,S_2,S_3) of the cell wall. The results obtained are as follows. 1) As the concentration of the silver nitrate solutions and the drying temperature were altered, particle size and its distribution range were changed (Maximum : 15-200Å, Minimum : 15-90Å). However the most common particle size, namely the peak value of distribution curves, was unchangeable in every case and the value was 40-45Å (Fig. 1. and Fig. 2.). 2) On the difference of average particle size among each layer of the wall, I+P layer was 30-60% larger than the layers of secondary wall. The difference of the size in each layer of secondary wall was slight. (Fig. 1.) 3) On the difference of particle number per unit area among each layer of the wall, S_1 layer had the most particles and the the value was 1.3-1.8 times as many as S_2 layer. 4) On the difference of particle volume per unit wall volume among each layer of the wall, the particle volume of I+P layer was greatest and the value was 2-3 times as much as S_2 layer. Next to the I+P layer, the particle volume of S_1 layer was 1.2-2.0 times as much as S_2 layer.
