    round specks, as well as in lines and stars. There is often evidence of disease of the choroid as well. The pigment is more often irregular in its arrangement than in the more characteristic cases not due to syphilis. Still I have no doubt that inherited syphilis is not infrequently the cause of affections which are spoken of as ' retinitis pigmentosa.' Believe me, &c., Jonathan Hutchinson. The following is the case referred to in the foregoing. Ophth. Jffosp. Rep., Vol. v., p. 324:—Case of ' Choroido-retinitis' in a girl, aged seventeen.— The central incisors most typically notched, but no history of syphilis could be obtained. OphtJiahnoscope.—Each eye the same. The discs of a dirty grey white, and the vessels so small they could only be traced with difficulty beyond the margin. There are but few denuded patches of sclerotic. The pigment was accumulated in 'blots' rather than stellate patches. There were a great number of these ' blots,' and more of them near the centre than at the perif)hery. Many of the pigment patches were in the retina itself. I confess I am much inclined to agree in Mr. Hutchinson's opinion, that many cases which are regarded as ordinary retinitis pigmentosa depend probably on inherited syphilis. Attention has been little directed to this point. Mr. Macnamara, of Calcutta, in his excellent Handbook of Diseases of the Eye, p. 401, says:—I am disposed to look upon the disease [retinitis pigmentosa] as a result of inherited syphilis. . . . . The only facts which, in my mind are opposed to this vieAv of its relation to syphilis are, that I have not noticed the notched teeth, nor have I seen the affection in more than one member of a family; and lastly, the disease does not seem to be influenced in the least by any treatment with which I am acquainted. II.—A Case of Dermoid Tumour of the Cornea. It needs only reference to any text-book of ophthalmology to ascertain that the dermoid is the most common form of tumour of the cornea. Its usual seat is on the outer border of the cornea, extending over to the conjunctiva more or less; indeed, it is as often described under the head of diseases of the latter membrane as among those of the cornea. These tumours are for the most
