that if you lift a breast feather you can see clean plumage underneath. I too wondered about coal or oil furnaces heating the buildings and other post-preparation sources of soot.<o:p></o:p></span></p>

<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
