Inspected passage: the publisher’s opening paragraph describes the earlier papain-powder digestion of rabbit anti-ovalbumin, loss of direct precipitation, and specific inhibition of precipitation with undigested antiserum. This earlier preparation is distinct from the later crystalline-papain procedure. The PDF endpoint served publisher HTML containing that paragraph and metadata; the entire two-page paper was not inspected. No apparatus dimensions, buffer recipe or measurements are inferred from unseen pages.
