is No way to prevent it!” 
In the discussion of anatomy and histology the author has followed 
the older lines more closely, too closely, perhaps. In the classifica- 
tion of the tissues, we had a right to expect the abandonment or sub- 
ordination of the three tissue systems of Sachs and De Bary, which 
test mainly on the course of early development and obvious but 
Superficial anatomical relations. ‘This is the more striking since the 
retention of these tissue systems is scarcely consonant with the adop- 
tion of the stele as a morphological unit, a step which we think emi- 
nently good. Neither is the treatment of the sclerenchyma and scler- 
Otic parenchyma as modern as it might be to its betterment.
