English: Plate XII from An Atlas of Gas Poisoning by the American Red Cross and Medical Research Committee (American Red Cross, 1918).

Plate title: PLATE NO. XIIA "Stage of resolution after severe burning." Text begins: "The vascular injection is passing off, the solid oedema is becoming absorbed, and the corneal epithelium has regained its normal lustre. In this stage the use of atropine should be discontinued."

Plate title: PLATE NO. XIIB "Late stage of resolution." Text begins: "The earlier vascular injection above and below the cornea has practically disappeared; the solid white oedema has been absorbed, and the conjunctiva in the palpebral aperture now shows definite injection, often of a bright violet tint. ..."

The American Red Cross published this guide for the American Expeditionary Force in World War I, sometimes called the "chemists’ war." The chromolithograph plates of characteristic injuries were intended to help inexperienced officers identify the type of gas used in attacks.
