A treatise on the diseases of the eye. ained at the inner part of the wall of the cavity, but they didnot appear to grow: from time to time, however, they were touched wdthchloride of zinc, or nitrate of silver. In September, 1865, he again applied, suffering from severe rheumaticpains in the right hip ; he had lost flesh, and the pulse was up to 100. The 788 DISEASES OF THE ORBIT. excrescences on the inside of the orbit, having increased in size (one was aslarge as a small nut), were cut away by Mr. de Morgan, and the tissuearound them destroyed by the chloride of zinc. The microscopic examination of the tumor, made by Mr. Hulke, showedit to be medullary cancer. The optic nerve appeared healthy on section ;but extending between the inner and outer sheath in the loose connectivetissue, were small diffused patches of cancer elements, lying in the meshes ofthe healthy tissue. ys:.- Fig. 252 shows the patients condition when he appeared before the Patho-logical Society, on February 6, 1866.^ He was then apparently quite Although the patient appeared to be quite well in February, 1866, he diedon July 11th, having lived one year and eight months after the had for some time suffered greatly from sciatica, which was soon followedby paraplegia. He had also vertical hemiopia of the remaining eye. Onpost-mortem examination, a large tumor Avas found in the middle fossa ofthe skull, growing apparently from the orbital .foramen and sphenoidalfissure, the optic nerve as far as the commissure being involved in, andundistinguishable fi*om it. Cancerous deposits were also found in the glandsaround the aorta, and adhering to the nerve trunks of the cauda orbit was empty, and free from any cancerous growth. The return of the disease, and its fatal termination, were consequentlyonly due to the fact that the optic nerve was involved in the cancerous affec-tion. Mr. de Morgan therefore thinks that these facts justify the belief that,had the operation been
