Fig. 19a. Microscopic Starch Crystals Resembling Cells 



The microscopic photographs shown here are taken from crystallizing 

 starch; note how the crystals form structures resembling cells, some even 

 remotely resembling living cells with a nucleus. Others exhibit definite 

 lines of separation between the cells. Magnification about 1730 times. 

 (Microphotographs by Bi'itschli.) 



Fig. 19 b. Miscroscopic Pictures of Nerve Cells 



Note the resemblance of these cells, containing a nucleus, to the starch 

 crystals shown in the previous figure.
