the materials. And the conception wrought out by Bichat, with his detailed study of the different tissues, acted necessarily on medical questions as the turning of gas-light would act on a dim, oil-lit street, showing new connections and hitherto hidden facts of structure which must be taken into account in considering the symptoms of maladies and the action of medicaments. But results which depend on human conscience and intelligence work slowly, and now at the end of 1829, most medical practice was still strutting or shambling along the old paths, and there was still scientific work to be done which might have seemed to be a direct sequence of Bichat's. This great seer did not go beyond the consideration of the tissues as ultimate facts in the living organism, marking the limit of anatomical analysis; but it was open to another mind to say, have not these structures some common basis from which they have all started, as your sarsnet, gauze, net, satin, and velvet from the raw cocoon? Here would be another light, as of oxy-hydrogen, showing the very grain of things, and revising ail former explanations.
