As "Disquisitiones" do naturalista Arruda da Câmara (1752-1811) e as relações entre a Química e a Fisiologia no final do Século das Luzes

This work is intended to rescue the field of validity of the "Disquisitiones" by the naturalist Arruda da Câmara placing them in the scientific and historical context of the end of the "Century of Light". Thus, a tentative is made here to reconstruct the debate established among the several theories that served as background of the relationships between Chemistry and Physiology of that time. In the present work is presented by the first time an integral translation of the "Disquisitiones" and a biographical resume of the naturalist in the historical context of his epoch in Northeast Brazil, especially in Pernambuco.
