PKBIOSTITM— PHAEyMdlTia. 107 



PEBIOSTXTIS (Inflammation of the Periosteum, 

 the Membrane covering the Bone) is not infrequently met 

 with in the dog, and as it usually arises from direct injuries, this is 

 hardly to be wondered at. Often it is associated with ostitis (in- 

 flammation of the bone proper). Periostitis is a most painful 

 disease. The membrane becomes much inflamed, swollen, and 

 separated from the bone, while frequently deposits of bone are the 

 result, causing permanent lumps (exostoses) ; these are generally 

 most unsightly. 



The symptoms of periostitis are heat and swelling of the skin over 

 the affected part, with great pain upon manipulation, lameness 

 when occurring in a limb, and feverishness. Strict quietude is most 

 essential in these cases ; hot flannels should be applied to the part, or 

 in severe cases, more benefit will be derived from hot linseed poultices. 

 When the heat and swelling have left the part, but lumps are present, 

 they should be painted with tincture of iodine, discontinuing this 

 latter treatment when the skin becomes sore.

FHABTI7GITXS (Inflammation of the Fharynz) 



Is not a disease which frequently affects the dog, and but few cases 

 have come under my immediate notice. I speak of pharyngitis pure 

 and simple, and not of inflammation of the pharynx as a result or 

 an accompaniment of other diseases. The latter form is common 

 enough. True pharyngitis is usually due to some foreign body 

 becoming lodged in the pharynx, though I have known it caused by 

 the administration of strong drugs, given with the object of curing 

 disease. In these cases the stomach suffers also. 



The symptoms are a dry, irritating cough, whUe as time goes on, 

 a difficulty in swallowing is observed, the act being performed 

 with pain ; the muscles of the throat contract, and upon manipula- 

 tion there is pain. Upon opening the mouth, and examining the 

 throat, it will be found red and swollen, and if the inflammation is not 

 checked, ulceration of the throat will ensue ; or abscesses may form, 

 when there wiU be a discharge from the nostrils. 



The treatment is primarily to ascertain the cause, and endeavour 

 to remove it. If the condition is due to the presence of foreign matter, 

 this latter must be removed, and a hot linseed poultice (kept in 

 position by a bandage) applied to the neck. The diet should con- 

 sist of milk, egg, and Bovril ; nothLugBjolidlmrist be given. Generally 

 this simple treatment will effect a cure ; , but should 'aloeration take 

 place, the part must be paintedl ^t4 a weak solufdon of nitrate of
