He also left the majority of his lab work to others during the last
many years of his life, only producing his own exhibition prints
(probably after recognizing he could pay someone else to take the risk
of playing with selenium toners, among other things).

Yes, yes, I know, you own some of his prints...

I'm not a doctor, but I play one on...

I disagree. If nothing else, the information regarding heavy metal
components of certain pigment mixes was quite valuable to me.  Keep in
mind the book was written some years back, and it was a good heads-up to
artists who tended to be too caviler about handing their materials.

Their concerns with ventilation of darkroom fumes is wise to heed.
