<p class="MsoNormal" style="margin-bottom:0.0001pt;text-align:justify">Plant exudates are generally sticky organic <a name="_GoBack"></a>materials that many plants produce (<a href="http://essential.metapress.com/content/1110865105v7q345/">http://essential.metapress.com/content/1110865105v7q345/</a>).
With time, they tend to become solid. One kind of plant exudate is resin;
fossilized resin is known as amber (<a href="http://essential.metapress.com/content/x117340n1t081165/">http://essential.metapress.com/content/x117340n1t081165/</a>).

<p class="MsoNormal" style="margin-bottom:0.0001pt;text-align:justify">Does your collection hold any one or more of these
types of materials? Typical departments where these materials are held include,
but are not limited to, are: botany, anthropology, and mineral sciences. If
“yes”, could you contact me (<a href="mailto:blayjorge@gmail.com">blayjorge@gmail.com</a>)
or Dr. Joseph B. Lambert (<a href="mailto:jlambert@northwestern.com">jlambert@northwestern.com</a>)?
We use small samples (100 milligrams, approximately the volume of a new eraser
on top of a pencil) of plant exudates, copal (partially fossilized resins), and
amber with excellent geographical (and in the case of copal and amber)
geological provenance. Some of these materials are used in archaeological
contexts (<a href="http://essential.metapress.com/content/339j6785701j146h/">http://essential.metapress.com/content/339j6785701j146h/</a>),
thus samples of such materials would also be appreciated.</p>
