[The (in)salubrity of prison life and other causes of death in Porto Alegre Prison, 1855-1888].

The article analyzes the flow of penal sensitivities in relation to medical and health care provided to prisoners in Porto Alegre Prison between 1855 and 1888. The internalization and the instrumentalization of concepts such as "humanity" and "civilization," especially by those individuals involved directly or with strong chances of influencing changes pertaining to penal issues, are observed. Indeed, in addition to generating favorable public opinion, the concerns of governing authorities and leading lights led to the development of concrete measures and practices that increased the minimum subsistence offered to the imprisoned class. This process, however, was far from linear and harmonic as witnessed by the diseases and the precariousness of prison life.
