About This Book

The document begins with an ante-mortem history of the conjoined brothers, describing their separate households, marriages, offspring, and progressive ill health including one brother’s hemiplegia followed by an acute respiratory episode and sequential deaths. It then presents a careful post-mortem examination performed some weeks after death, giving body measurements and external findings such as variable congestion and discoloration, detailed anatomy of the abdominal commissure connecting the two, and systematic observations of thoracic and abdominal organs, including differences between the two bodies and focused descriptions of the spleen and related structures.
