of " a variety of applications" remained undiminished for several 

 weeks afterwards. The horse was in consequence sent to his regi- 

 mental duties ; and while there, the opacity gradually and slowly 

 lessened, to a degree that, nine months afterwards, it had decreased 

 half its original dimensions. 



It has happened that the worm has not made its escape with 

 the aqueous humour ; and in consequence, a second operation has 

 become necessary, after giving time for the reunion of parts and 

 the fresh secretion of the humour. As Mr. Molyneux has perti- 

 nently observed, however, the worm might after the first evacua- 

 tion — and would, I should imagine, be very likely to — '' die within 

 the eye," and which he tells us "often happens;" and then it will, 

 " like any other foreign matter, become absorbed." Still, Mr. Gibb 

 informs us that, repeatedly, the worm has survived, and for its 

 extraction has required "a second operation." 



FUNGUS H^MATODES. 



The formidable disease to which the appellation of fungus 

 hcematodes or bleeding fungus, was first given by that celebrated 

 surgeon, Mr. Hey, of Leeds, is also described by others under the 

 appellations of spongoid inflammation, medullary sarcoma, and soft 

 cancer. 



Though hardly any part of the body can be said to be insus- 

 ceptible of it, the parts in which it has been most observed are the 

 brain and the testicle, and, above all, the eye. It has likewise 

 been seen in the mammae and in the extremities, and in the walls 

 of the heart*. Many cases stand recorded of persons suffering and 

 dying from dreadful inflictions of this nature ; but, fortunately for 

 us, and still more for our patients, the brute creation affords but 

 few and rare instances of it. This has enabled surgeons to frame 

 an account of the disease comprehending the features of the ge- 

 nerality of cases as they commonly present themselves, and such a 

 one as may, as an outline, prove useful to us ; and, therefore, I 

 shall transcribe it, selecting, as the best I can find in relation to 

 the eye, that given in the excellent work of Dr. Mackenzie*.
