Is it formalin or saline

From:David Grehan <david.grehan@olhsc.ie>

Have you ever been asked if a specimen has been placed in formalin or
saline but you are reluctant to have a sniff and blast your mucous
membranes?.
Here is a simple test ;
Add  few drops of the fluid to 1 ml of your reticulin silver solution.
If it turns white the fluid is saline.
If it turns black you have got formalin .

Easy!
