[Nhcoll-l] NYT article: Soot on early 20th century specimens

[Erin Cashion]

Hi all,

I mentioned in my post regarding the historic taxidermy case last week that some of the specimens inside appear sooty. One person replied that it may be caused by mercuric chloride (applied as a preservative during preparation). A couple other people suggested it may be the result of coal dust in the air at their storage location(s) due to coal heating, rather than soot collected from its habitat in life. The study linked below is suggesting the latter. I'm curious how they determined the difference between these two carbon contaminants.

In any case it's wonderful to see natural history collections making the mainstream news!
