 then bOCl an entire fruit or a partial fruit for a raoment in a 

 strong etching-potassiunr Solution, then you can see with ease und er the 

 magnifying glass with a needle the keel-cells and likewise the inside 

 of the fruit; and generally dissect the pericarp even on fruits, which- 

 had been dried. The lack of crystals and the weak reinf orcement lasts
