THE Museum has established a Research Laboratory fully equipped for the study, treatment, and restoration of archaeological specimens in all the various media. The laboratory is under the direction of Dr. A. K. Graham of the Chemical Department of the University of Pennsylvania. The various objects already reclaimed by the combination of electro-chemical and chemical means are now on exhibition among the Ur Collections. Of the silver vessels many were so completely corroded as to be unrecognizable before the laboratory treatment given them by Dr. Graham, and in the case of many others the processes revealed elements of decoration that had been completely obscured.
An article by Dr. Graham describing in detail his methods and results is published in the December issue of the Museum Journal.
