Dark Slides don't fit ARE NOT X-RAY Slides

After a bit of embarrasment with the seller of the slides that didn't
fit, and after this tread diverged into the conviction that they were
X-RAY slides, I have come to find out that they fit old wooden Kodak
holders, all shorter, wider and fatter, of them. I need to bone up on
my scientific process, and keep a cautious eye tilted to the
"authorities" here.

Ah, thank you. Now we are all smarter.

I need to bone up on my scientific process

Most everything said here is disprovable, so it fits with the Popperian
definition of scientific.

and keep a cautious eye tilted to the "authorities" here.

Very good idea.
