On the morning of April 1, 1943, four Hereford calves varying in age from three to ten days were presented at the Stange Memorial Clinic. Three of them were females; the other was a male. All were in excellent general condition. The history revealed that the calves were having eye trouble. Examination of the eyes disclosed peculiar growths at the sclero-corneal junction which had the appearance of skin furnished with a hairy covering. Other symptoms included erythema of the eyelids and excessive lacrimation with consequent formation of crusts around the eyes. Two of the calves were bilaterally involved; the other two each unilaterally involved. In two cases the hairs were brown in color; in the other cases they were white. The growths did not seem to impair the vision of the calves except for the mechanical interference and irritation they produced.
