My email response bounced, so I'll post my response here. What kind of
'inconstancy' are we talking about. How do you apply the LY ? We work
on a related animal (Lymnaea), and are planning to use photo -inactivation
in the future. I am therefore very interested in your problem. It would
be nice if we could get the email working.
