The flyer serves as an invitation to the organization's General Assembly, noting date, time and venue and purpose. "You are invited to participate in the General Assembly of the Founding members of the French Association…Mr. Claude Bernard, president…The meeting will define the final constitution of the Society...." Broca writes to his associate, Dr. Azam, "I am quite sure that you will not be here for the Wednesday event. But you could send me, on your behalf and for your two subscribers, a letter informing the president that you approve the by-laws...." Signed, "P. Broca."
Broca's early scientific works dealt with the histology of cartilage and bone, but he also studied cancer pathology, the treatment of aneurysms, and infant mortality. One of his major concerns was the comparative anatomy of the brain. A long and substantive letter throughout.
