Though there areoccasional reports of irritationfrom its hairs such cases arerare and there is no evidencethat there is any poison pres-ent. Indeed, subcutaneousimplantation of the hairsleads to no poisoning, but merely to temporary irritation. Occasionally, the hairs of certain species of caterpillars find lodge-ment in the conjunctiva, cornea, or iris of the eye of man and giverise to the condition known as opthabma nodosa. The essentialfeature of this trouble is a nodular conjunctivitis which simtdatestuberculosis of the conjunctiva and hence has been called psetido-tubercuJar. It may be distinguished microscopically by the presenceof the hairs. Numerous cases of opthalmia nodosa are on record. Of thosefrom this country, one of the most interesting i
