content: The glass plate and film negatives consist of gelatin dry plates (4" x 5" and 8 1/2' x 10") and are arranged numerically.  The plates and film negatives are not inclusive and there are two numbering systems.  There are some film negatives interspersed with the glass plates and these film negatives also have numbers. Researchers should consult the partial index to the glass plates in box 68, folder 7.

The condition of the negatives varies, with some negatives showing significant signs of deterioration.
