284 DISEASES OF THE HORSE. 
Encysted, honeylike (melicerous), sebaceous, and fibrous tumors of 
the lids all require removal with the knife. 
TORN EYELIDS OR WOUNDS OF EYELIDS. 
The eyelids are torn by attacks with horns of cattle, cr with the 
teeth, or by getting caught on nails in stall, rack, or manger, on the 
point of stumps, fences, or fence rails, on the barbs of wire fences, 
and on other pointed bodies. The edges should be brought together 
as promptly as possible, so as to effect union without the formation of 
matter, puckering of the skin, and unsightly distortions. Great care 
is necessary to bring the two edges together evenly without twisting | 
or puckering. The simplest mode of holding them together is by a 
series of sharp pins passed through the lips of the wound at intervals 
of not more than a third of an inch, and held together by a thread 
twisted around each pin in the form of the figure 8, and carried 
obliquely from pin to pin in two directions, so as to prevent gaping 
of the wound in the intervals. The points of the pins may then be 
cut off with scissors, and the wound may be wet twice a day with a 
weak solution of carbolic acid. 
TUMOR OF THE HAW, OR CARIES OF THE CARTILAGE. 
Though cruelly excised for alleged “hooks,” when itself perfectly 
healthy, in the various diseases which lead to retraction of the eye 
into its socket, the haw may, like other bodily structures, be itself the 
seat of actual disease. The pigmentary, black tumors of white horses 
and soft (encephaloid) cancer may attack this part primarily or 
extend to it from the eyeball or eyelids; hairs have been found grow- 
ing from its surface, and the muccus membrane covering it becomes 
inflamed in common with that covering the front of the eye. These 
inflammations are but a phase of the inflammation of the externa] 
structures of the eye, and demand no particular notice nor special 
treatment. The tumors lead to such irregular enlargement and dis- 
tortion of the haw that the condition is not to be confounded with 
the simple projection of the healthy structure over the eye when the 
lids are pushed apart with the finger and thumb, and the same re- 
mark applies to the ulceration, or caries, of the cartilage. In the 
latter case, besides the swelling and distortion of the haw, there is 
this peculiarity, that in the midst of the red inflamed mass there 
appears a white line or mass formed by the exposed edge of the 
ulcerating cartilage. The animal having been thrown and properly 
fixed, an assistant holds the eyelids apart while the operator seizes 
the haw with forceps or hook and carefully dissects it out with blunt- 
pointed scissors. The eye is then covered with a cloth, kept wet 
with an eyewash, as for external ophthalmia.
