 Dear Doctor


 Your acceptable notes
 of the 8th - 11th are before me.
 Allow me first to say in reference
 to a previous one that I had not
 part in sending that letter to
 Mrs Shaw which was so long
 delayed.


 I find we can do nothing
 till we can settle our Terminology - 
 Unfortunately I have no good
 model and have drawn up the
 accompanying paper at random.
 Will you please correct it into
 a practicable shape that we
 can nail to the mast.


 I dont see why when once settled
 it may not be developed into
 a description or definition of
 ferns. I rather want to consider
 the stipes as a part of the
 Frond - 


 I find your description
 of Polypodium procerum page 21 utterly
 beyond my comprehension
