Lombroso's research methods were clinical and descriptive, with precise details of skull dimensions and other measurements. He did not engage in rigorous statistical comparisons of criminals and non-criminals. Although he gave some recognition in his later years to psychological and sociological factors in the etiology of crime, he remained convinced of and identified with, criminal anthropometry. After he died, his skull and brain were measured according to his own theories by a colleague as he requested in his will; his head was preserved in a jar and is still displayed with his collection at the Museum of Psychiatry and Criminology in Turin.
