Disease of the lachrymal gland, which secretes the tears, and obstruction of the lachrymal duct, which carries any excess of their secretion into the nasal cavity, are morbid conditions only occasionally met with in veterinary practice in this country. The same remark may be made of redness and ulceration of the edges of the lids with the loss of eyelashes, "Blepharitis ciliaris"; constriction of the opening of the eyelids, "Blepharophimosis "; irregular arrangement of the eyelashes, "Triachiasis"; adhesion of the eyelid to the globe of the eye, "Symplepharon"; and other affections which are met with in the human subject but are seldom seen in the eye of the horse.
