. and Carcinoma of the Eye. 345 



pearing to be the complete extirpation of every part that is 

 diseased. Before recourse be had to the opcralion, it is 

 necessarv io ascertain, as far as possible, that every such 

 part is capable of l)eing reniovetl ; since, in both disorders, 

 if the smallest portion that has been contaminated remain, 

 whether it join the organ that is extirpated, or be at a di- 

 stance from it, the diseased part will infallibly increase, 

 and all the old symptoms be reproduced. The fungus h«- 

 matodes is not always confined to one eye, nor even to both, 

 but sometimes occupies a large portion of the orbit exterior 

 to the tunics of the eye. It is also accompanied not unfre- 

 quenlly u'ith abscesses and tumours in different parts of the 

 bead ; sometimes between the pericranium and cranium, 

 and at other limes between the cranium 'and dura mater. 

 These abscesses are not confined to the fore part of the 

 head, haviniz; sometimes been found both on the outside 

 and inside of the os occipitis. Distinct portions of matter, 

 and sometimes hard tumours, have also been formed in the 

 ilura mater, and even in the substajice of the cerebrum ; and 

 someiimes under the anterior lobes of the cerebrum, making 

 a compression on the thalami nervorum oplicorum. A 

 disease of this kind is by no means new. It has occasion- 

 ally come under my notice ever since I was a boy; and it has 

 been described by many of our ancestors under the common 

 name of carcinoma, or cancer. It may be more correct, 

 however, to distinsuish it by the term fungus ha:ma!odes, 

 «r medullarv sarcoma, thouirh it does not appear to me to 

 be aUvavs easy to ascertain the difference between the twr> 

 disorders. It has been said that carcinomatous afleclions 

 are always preceded bv a bard circumscribed tumour, and 

 thai, after an ulceration has been produced, if'it be followed 

 by a funirous excrescence, tins is of a cauliflower figure, and 

 a hard firm texture; but such cannot be admitted to be the 

 universal progress of these affections, nor is it uidike to that 

 which the fungus hasmaiodes sometimes assumes. It may 

 be said with greater correctness, that the carcimin.i of tlic 

 eye is a disease to which persons are most subject in the 

 middle or latter part of their lives, whereas the fun<rus haj- 

 niatodcs appears in early life, and moiit commonly in in- 

 lancy. 



The following is the progress of a di'oidcr which I have 

 also repeatedly seen in persons advanced in life, but do not 

 remember in anv who were young. By some it may bo 

 railed fungus hannalodei, and by others crucinoma ; but I 

 ^luill content myself with di-cnbiiig it. 'llie sight is lost
