cannot lie still, and the state is so marked as to be easily 

 recognised. 



INFLAMMATION OF THE EAR : INTERNAL CANKER. Greyhounds are 

 not very subject to this troublesome complaint : but, when it does 

 occur, it interferes with their rest, and prevents their reaching 

 that high state of health which is the object of the courser's desire. 

 Sometimes, however, after severe weather, to which the dog has 

 been exposed, he is seen to be annoyed with something about the 

 head; he is evidently in pain, and shakes his ears, but not 

 violently. On examining the interior of the ear it is seen to be 

 highly inflamed, and, in a day or two after, a thick matter 

 frequently makes its appearance from the passage. The redness 

 often extends to the inside of the outer ear. After a time the 

 pain becomes less, but the dog is always scratching or shaking his 

 ears, and can take no rest. From the constant shaking the tips 

 of the ears become sore and cracked; and this is often thought 

 to be the seat of the disease, whereas it is only the effect. 

 Attention is consequently paid to get rid of the ulceration, and 

 the ears are even confined by a cap: all this is useless. The 

 only remedies likely to be useful are general lowering measures, 

 as starvation and purging, in the early stage, and, if the attack 

 continues, a seton. The nitrate of silver solution (ten grains to 

 the ounce) should be carefully introduced into the passage every 

 day, previously washing away with tepid water by means of a 

 syringe any pus or mucus which may have accumulated. 



EXTERNAL CANKER is an eruption on the tips of the ears, like 

 that attending the internal inflammation, but without that com-
