The notes which follow are a combination of several papers contributed to the Institute during the last few years. They are mainly the consequence of opportunities offered by Professor Flinders Petrie’s kindness in permitting an examination of specimens found by him; but many other collections have also been studied. Mr. Petrie’s specimens have the special value of being correctly dated. The chief of the notes are devoted to three periods in the older Egyptian history—the Fourth, the Twelfth, and the Eighteenth Dynasties. Though this involves some repetition, the examination of each series separately helps to mark chronological changes.
