Though there are occasional reports of irritation from its hairs such cases are- rare and there is no evidence that there is any poison pres- ent. Indeed, subcutaneous implantation of the hairs- leads 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 give rise to the condition known as opthalmia nodosa. The essential feature of this trouble is a nodular conjunctivitis which simtdates- tuberculosis of the conjunctiva and hence has been called psetido- tubercular. It may be distinguished microscopically by the presence' of the hairs. Numerous cases of opthalmia nodosa are on record. Of those from this country, one of the most interesting is reported by de Schweinitz and Shumway (1904). It is that of a child of fifteen years whose eye had become in- flamed owing to the presence of some for- eign body. Down- ward and inward on the bulbar conjunc- tiva were a number of flattened, grayish- yellow nodvdes, be- tween which was a marked congestion of tVlp rnniiino-f-iiT-Ql anrl *^- (o) Nodular conjunctivitis in the eye of a child. tne conjunctival ana DeSchweinitz and Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Riley, William A.
