72 POLYPUS IN THE PHARYNX.-ON FAliCY. 
I then performed the operation of tracheotomy, and let the 
mare rise; she was much relieved, and ate and di ank better. 
I took a little blood from her, and gave an aperient mixture, 
which had the desired effect. 
She continued to do well, and in four or five days I gave her 
exercise, which she bore well; even trotting and severe exertion 
did not produce any of the former symptoms. She continued 
thus for a fortnight, when she altered for the worse, and began 
to toss her head and catch her breath with difficulty, whilst 
eating. Her appetite decreased, and she gradually got worse until 
she scarcely ate or drank any thing; in fact, I found she was as 
bad as when she first came to me. 
I cast her again, and felt the same substance as before; I 
grasped it with my fingers, and pulled with all my power, but it 
resisted my efforts. I then got a cord, and made a running 
noose in it, which I put round the neck of the substance, and 
tried to drag it from its hold : my efforts broke the string. I got 
another cord, and again secured it round the substance, and this 
time I succeeded in pulling away a lump as large as a hen’s egg. 
It appeared to come from the roots of the tongue, and when the 
mare was in exertion and obliged to take deep inspirations, to 
have acted as a valve upon the epiglottis, and to have required a 
powerful effort to displace it, and hence was the cause of the fits. 
On the next day 1 gave oatmeal gruel and bran mashes : the 
second day after the operation I found her breathing heavily, 
and I took four quarts of blood from her : this relieved her, and 
she became tranquil. In a few days she ate vetches, and grazed, 
and continued to go on well without further medical treatment. 
I suffered the tube to remain in the trachea about ten days after 
I had taken away the tumour; I then removed it,and healed up 
the orifice. 
She can now travel with perfect ease, and is quite sound.

Cold damp situations—living and working amidst the waters— 
ill-constructed stables—are they alone capable of producing the 
farcy eruption ? 
It very widely exists in Egypt, more in summer than in winter, 
in the villages, the army, among the Bedouins, in horses that 
are confined, and in those that live in the open air. There the
