This find really takes the cake. While visiting a little-traveled area of the Detroit Historical Society's collection, our Curator came upon an unassuming glass jar that contained porous, brown chunks of what appeared to be sea sponges. What are these things? Or perhaps more to the point-what were these things? The mystery was short lived as a label became visible on the other side of the jar.
