Dodge Chemical Co. "Ontro Fix" Cavity Fluid Bottle, Boston, Circa 1940s-1950s

Clear glass bottle with the "Ontro Fix Cavity" label, "the cavity unit of the new Ontro chemicals," from The Dodge Chemical Co., Boston. Cavity fluid was used to preserve the torso after arterial embalming. A good companion to the Ontro Tone arterial bottle. Light wear to the label.
