• A chemiluminescent material (Cyalume) was injected into the lacrimal excretory passages of eight normal monkeys (16 eyes). Patency was established by almost instantaneous observation of a yellowish-green glow in the nose and pharynx. No toxic effects of the chemical were noted in any of the monkeys.
