[Nhcoll-l] cleared and stained amphibians

[Haff, Tonya (NCMI, Crace)]

Hello all,

We have some cleared and stained small frogs that are, I suspect, stored in a mixture of glycerine and ethanol. I have read in John's Fluid Preservation book that some people use a mixture the two at a 1:1 ratio (but at what ETOH concentration I am not sure), but I wonder if any of you would share how you store similar specimens? Some of the jars need to be topped up, so I also wonder if it's best to top up using a 1:1 ratio of glycerine to ethanol (given that's what it *looks* like, ha ha), or remove all fluid and replace, or...? Thoughts, as usual, appreciated!

Cheers,

Tonya
