Paleobotany is what this one is all about! Bill DiMichele and coauthors tease out important data on the 1940-41 fossil plant collections from five stratigraphic levels by field geologist/paleobotanist Charles B. Read, whose field notes cannot be located. Thus secondary sources were used to assess stratigraphic intervals covered by the collections. Specimens examined are in the permanent collections of the Smithsonian's National Museum of Natural History.
The Smithsonian’s National Museum of the American Indian building on the National Mall in Washington, D.C., has a significant problem with dark staining on its facade. This volume brings together papers from studies undertaken by the Smithsonian’s Museum Conservation Institute to understand the staining problem, suggest procedures for the 2011 cleaning intervention, and propose test studies for the development of a maintenance plan for the building.
