unnecessary to proceed further with the case. The horse was sent 
to Newry merely for the operation, which seems, by the plaintiff’s 
own witnesses, to have been properly performed. The action 
absolutely charges Mr. Small with neglect for not doing that which 
appears to he impossible .—I DISMISS ON THE MERITS.

I. Disease of the Skin and subjacent Cellular Tissue. 
Morbid changes in the colour of the skin of birds is easily 
observed, on account of the transparent epidermis with which the 
cutis in birds is amply provided, and particularly if the yellow 
colour prevails, which is caused by an overflow of the bile; or the 
reddish or blueish, arising from congestion. Melanotic deposits are 
unknown in birds. The pale colour of the crest in the galinacise 
is a symptom of a variety of disease in fowls. 
Eruption of the Skin. —Of this affection birds suffer little. 
We know but of one, the variola , to which fowls and pigeons are 
subject. On the contrary, the subjacent cellular tissue is frequently 
the seat of considerable swelling. On a hen I found two tumours 
the size of an egg : they were formed of microscopic cells ; their 
growth seemed to have been slow, and to have much affected the 
general health of the birds. After feeding on narcotic plants, 
considerable emphysema of the cellular tissue has been observed. 
Dr. Spinola has observed a peculiar morbid state of the web 
of the feet of a goose in a district where cattle had been much 
affected by the aphthous disease in the feet. 
A diseased state of the pyloric glands (glandulae urapygii) fre¬ 
quently occurs. It consists in the obstruction of the ducts, and is 
caused by an accumulation of the secretion, a dryness of the skin 
and feathers, and swelling of the parts.
