paul revere, who we know for his midnight ride to warn the colonists about advancing british forces also did work as a dentist. these tools were used by revere and we think we're probably related to work you did on a man -- related to work he did on a man named joe warren. he was a colonial leader, fought and died at the battle of bunker hill. the story is told, revere helped identify warren's remains from a mass grave and did so because you done some work on his teeth before he was killed. a unique feature for our visitors who come to the museum here at silver spring is the chance to see through the looking glass into a working museum laboratory. this special laboratory is to to care andped manage the artifacts and the museum procare. you see a range of human remains, anatomical specimens, bones, laid out on the counter there. a museum staff person will do some lab work in preparation for dealing with objects and conservation. but we could use this lab to manage paper materials, other types of tissue, or to prepare outfits for long-term display. so, our last stop on our visit is where w
