Scientism and The Art of Picture Cleaning.

The author reflects on the scientism and the art of picture or painting cleaning. He cites the discussion relative to the topic that was published in the journal's previous articles, particularly the report from the National Gallery in October. He comments that the report at first glance shows to be refutations of the alleged misleading statement in its original paper, and had an oversimplification of what is known about the two soluble resins (the dragon blood and gamboge).
