XXVIII.—On the Development of Starch and Chlorophylle 
Granules. By Cantu Nace i*. 
In the actual punctum vegetationis there is nothing but a homo- 
geneous mucilage (protoplasma of Mohl). This becomes finely 
granular in the lower part; it is here that the deposition of the 
fibres occurs. If we examine the fluid of the cell from this part 
(the fibre zone) of a young leaf or stem, we find in it very small 
granules, the -diameter of which does not exceed 008 of a line, 
and in these consequently nothing is to be made out. In the 
vicinity are cellules or utricles of from -001 to -0025 of a line ; 
they are filled with a thin yellowish mucilage, which, in the smaller 
appears homogeneous, in the larger finely granular. Somewhat 
lower down (the starch zone) the formation of amylum takes place ; 
the young leaf there becomes of a shining white colour. The cell-
