O.K. It's my child (DELIEU T, DA WALKER 1981 Polarographic measurement of
photosynthetic O2 evolution by leaf discs. New Phytol 89: 165-175) so I'm
bound to love it
³As a child, learning to swim, I had not at first opened my eyes under
water, more
fearful perhaps of injury to my sight than drowning. When I realised that it
was safe to
do so it was, of course, a revelation. When Robin Hill introduced me to the
Clark
electrode (Clark 1956) it was much the same. The ability to undertake
continuous
measurement; to see immediately the consequences of experimental
intervention is
immensely liberating. Sadly, however, the apparatus then available was far
from ideal.
Following Ohmar Khayam¹s edict, Tom Delieu and I therefore sought to ³crush
this
sorry scheme of things entire and remould it nearer to the heart¹s desire².
I made pencil
drawings on the backs of envelopes. Tom, a master craftsman, turned these
into
physical reality².
But don't believe me. Go to Scirus
http://scirus.landingzone.nl/other/
and enter ³leaf-disc electrode². Speaks for itself.
I hope that I don¹t need to add that I don¹t get a percentage on the sales.
Anyway we made our
own but you do need a modest workshop and a bit of a genius with his hands
like the late Tom Delieu.
Best regards
David
