Among the many treasures in the Warren Museum of the Harvard University Medical School is a collection of about 1,000 skulls (complete or incomplete). If one excludes those which are fastened to the bony skeleton or to the vertebrae by their ligaments and the skulls of children, there are about 800. These may be divided into two groups, the first representing chiefly donations of about 300 skulls from various sources and the second a formal group of 500 skulls of prehistoric Peruvian Indians.
Of the first group, many of the skulls came to the Warren family through personal friends in the early years, from 1783, when their historical collection was begun, and almost all the donations were made several years before 1847, when the Warren Museum was given to the medical school and established there.
