a) Ten Berkshire sows at one piggery in Kagoshima, in south Kyushu, farrowed one hundred and nine pigs, in 1950 and 1951. Fifty-four of them were born without eye balls. Sense organs of these blind pigs were researched anatomically and embryologically. b) There are many anatomical abnormalities, such as projected or depressed eye ball, little lens, thin pigmentlayer, lost retina and corna springing up hair. Undergrown optic nerve which has fine nerve fibre, ends to optic papillae, but never enters into retina. Strictures of sulcus decussatio and canalis fasciculi optici are remarkable. c) Since the development of vesicula oculi is held in check on early stage of embryo, the outer layer of cupula oculi becomes the thin pigmentlayer, and the innerlayer of cupula oculi disappears. As the opticstalk is little, the sulcus decussatio and canalis fasciculi optia becomes narrow.
