Today I started sorting my rather large slide collection and discoved some slides I made 57 years ago. And then I saw Neal Shields
posts of today where he pondered why someone would spend a lot of time incorrectly mounting a specimen that would not survive for at least 50 years.

This Black Fly (Simulium luggeri, male) is a Canada Balsam mount from 1965. The CB has turned to orange-yellow but this was easy to correct with one click in Photoshop. I rather prefer the original!

Re: An old slide
The Canada Balsam may have yellowed, but at least it still looks beautifully homogeneous
… orders of magnitude better than the dreaded NuMount crystallisation !!

Re: An old slide
Michael,
Interesting comments. I have used synthetic mounting media in the past and found that after several years the coverslips simple fell off. I now stick with Euparal and Canada Balsam.
