<p class="MsoNormal">Our wet mollusk collection used to have jars containing multiple individual lots in separate glass vials, stoppered with cotton. We abandoned this practice in favor of individual vials or jars for each lot (like Andy’s fishes, mollusks
are cataloged as lots, not specimens). The reasons were:<o:p></o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">The failure of a single lid doomed all the lots in the jar<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">There was some evidence that exudates from one lot (such as mitrid snails, which can give off dark, tissue-staining fluids for months after pickling) were contaminating the whole jar<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Retrieving individual lots (for a loan, for example) was a messy business<o:p></o:p></li></ul>
<p class="MsoNormal">The original justification for keeping multiple lots in a jar was to save space, but we came up with a storage system that allowed individual containers in a smaller footprint. You can see it at:<o:p></o:p></p>

<p class="MsoNormal">A smaller number of larger jars wastes more space than the opposite; think about the “spandrel space” between four jars on a shelf.
