FUNGUS HiEMATODES. 141 



" The patient becomes affected with great constitutional irri- 

 tation. 



" The Duration of the Disease is very variable. 



" The Appearances on Dissection are very far from being 

 uniform ; they may all, however, be referred to the effects of a 

 medullary growth from the optic nerve." 



This general description of the characters and progress of the 

 disease, as it invades the eye of man, will be found in most re- 

 spects applicable to the same disease in the horse's eye. The fol- 

 lowing case, contained in The VETERINARIAN for 1835, pro- 

 nounced by a surgeon, whose opinion was sought concerning it, 

 " to bear all the specific characters of the disease in the human 

 subject," will, I think, fully warrant me making this assertion, at the 

 same time that it affords a striking instance of the great assistance 

 we may on occasions receive from our sister science — medicine : — 



Mr. God^vin, V.S., Birmingham, " was requested by J. Walker, 

 a farrier in Lichfield, to see a case for him which he had been at- 

 tending, viz., 'a mare (to use his own words) out of wdiose near 

 eye some proud flesh had grown, until it had turned the eye inside 

 out.' He had at different times 'cut and causticked some pounds 

 away; but it grew as large as ever again in a very short time, and 

 bled a good deal whenever it was touched.' 



" I went with him, and found a fungoid tumour growing from 

 the near orbit ; soft, but resuming its shape after the removal of 

 pressure, and bleeding considerably after examination. Upon in- 

 quiry, I learned that the tumour had existed five or six months; 

 but she had been blind of the eye affected several months previous 

 to the appearance of the tumour. The ball of the eye, in the first 

 instance, was noticed to have become considerably enlarged, and 

 this increased until the cornea burst, when a small vascular tumour 

 protruded, forcing before it the contents of the sclerotica, and dis- 

 tending this tunic to such an extent as to cause the farrier's asser- 

 tion of the 'eye having been turned inside out;' a description of 

 the case not so inappropriate as, in the first instance, it appeared to 

 be. From this period it grew in size rapidly: portions of it had 

 been removed several times by different means; and her health 

 had continued pretty good until within the last few weeks, when
