Human skeletal remains have been recovered from prehistoric and early historic sites in Louisiana with some degree of regularity for the past 75 years and on an irregular basis for the last 300 years. During his explorations of aboriginal sites throughout the Lower Mississippi River Valley, Moore made a special effort to collect skeletal specimens for shipment to the US National Museum at the Smithsonian Institution. A less well-known fact is that he also collected pathological specimens for shipment to the Army Medical Museum at Walter Reed Hospital in Washington, DC. An unfortunate aspect of the Moore recovery technique, however, was the practice of discarding unwanted bones, which introduced an implicit selection bias in the National Museum cranial series from Louisiana that Hrdlička subsequently studied. Whether or not Moore selected specific samples of pathological bone for the Medical Museum is not known
