    it is a fact that pannus is invariably a characteristic feature of the granular stage. Another circumstance which upsets the friction theory is that the corneal epithelium is in good state of preservation wherever superficial pannus is present; it is sometimes hypertrohied but rarely absent. Prolonged friction destroys the epithelium and is the cause of facettes. In negroes I have very frequently seen large patches of pigment on the vascularised parts of the cornea; such pigmentations do not disappear after the obliteration of the newly formed blood-vessels, and they interfere considerably with the vision. Owing to this circumstance, pannus is a much more serious complication in the coloured race than in the white. It must also be remembered that friction is altogether absent in the other forms of vascular corneitis such as the subendothelial pannus following chronic iritis and plastic iridocyclitis, or the parenchymatous vascularisation of the cornea in interstitial corneitis, or the pannus accompanying tubercular conjunctivitis with ulcers on the cornea. Kerato-ectasia ex panno has come frequently under my notice. In many cases, especially in the rapidly pro- gressive cases there was more or less iritis with considera- ble or total posterior senechiae. Iridectomy proved of marked benefit in all the cases in which circular senechiae were present. It was easy to detect these by oblique illumination. Atropine has little or no effect on the iris of any eye affected with considerable kerato-ectasia ex panno. This circumstance and the efficacity of iridec- tomy have led me to suppose that there is a certain amount of anterior glaucoma in such cases, which is brought on by obliteration of the channels of filtration of the cornea. This may be the direct consequence of the subepithelial formation of connective tissue all around the liinbus and the canal of Schlemm. It is evident that any degree of iritis and anterior senechiae must accelerate the bulg- ing of the cornea, the elasticity of which in such cases is supposed to be impaired.
