of looks like what happened to a handful of our specimens. If I recall correctly, it had something to do with the concentration of formalin in the specimen when switched to (in our case isopropyl) alcohol. We didn’t stage them long enough in enough steps when
we put them into 70%, which caused the crystallites to form. <o:p></o:p></span></font></p>

<p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size:12.0pt">I recently found some bizzare white granules in some our ethanol preserved specimens. See the attached photos. The white granules tend to stick to the items in the jar,
rather than rest at the bottom of the jar. They do not crush easily (like I imagine precipitates would), but instead squish more like tiny styrofoam bits or pieces (like I imagine mold would).<o:p></o:p></span></font></p>

<p class="MsoNormal"><font size="3" face="Times New Roman"><span style="font-size:12.0pt">Has anyone seen this before? I washed the specimens and jars in fresh 70% EtOH, and then replaced the EtOH in the jar. So far no new granules have appeared. If anyone
has any better ideas of what this might be or how to treat it, I'm very interested.<o:p></o:p></span></font></p>
