          to make the descriptions so full that
an opinion could be formed on the proposed
species, from the descriptions alone, (all-
owing for errours) - Is there anything that
you noticed that should be altered in the
succeeding ones? Excuse me if I commit
the not unnatural mistake of supposing
every one else interested in what so much
interests me. To make up for all, I can
promise really handsome sets of specimens
of everything that I formally describe. 
I hope to continue with another 
article on Potamogeton immediately - 
after which I must wait the oppor-
tunities of another year. Sir W. Hooker
has most kindly informed me of his
having selected for me the Potamogeton
he has to send. I mentioned your kind
suggestion to Dr. Boott, and more gene-
rally to Sir William himself - and 
hope soon to thank you in spirit
