Toronto. Two days ago I posted a note on using x-rays to bring out daguerreotype images long thought lost in damage and tarnish. The earlier article was printed in the Globe and called to my attention by John Linsky. This time Russ Forfar sent an email about an article on the same process in the Science Daily.
The Science Daily article dated June 22nd gives different details on the process and covers the work of scientists at the University of Western Ontario. over in London, Ontario, about a two hour drive from here.
