Thank you Dr. Gochfeld for the report on xylene. I was misinformed
about xylene.

Clarification: Xylene can be used as a thinning agent for Canada
balsam, and isopropyl alcohol can be used as a thinning agent for
Euparal (considered by me to be better than 'Essence of Euparal'). The
trade off I attempted to describe is between Euparal/isopropyl alcohol
(takes a long time to cure) and Canada balsam/xylene (cures quickly but
gives Jim a splitting headache even in well ventilated areas).
