The eyeball presents no marked deviation fioni normal , if the eyeball of a full-time fietus is employed for purposes of control,the following ditterences appear:— («) The optic nerve cells are more scanty and are smaller in theCyclopean specimen. {h) The whole retina is shallower. This, of course, may be due to theearlier age of the specimen, but it is noteworthy that the main dlHcrences.

Of the first specimen, theright eye has been removed for histological examination, appear in the layer of rods and cones and the strata which would corre-spond to the molecular layers in the normal eye. These layers are muchbetter developed in the contiol. On the other hand, the inner nuclearlayer is, relatively speaking, as distinct as it is in the control. III. Cextkal Nervous System.
