Diseases of the Digestive System. IgI 
enumerate them. The more common are stones, &c., 
which the animals are taught to seize or carry, which may 
be swallowed. Others have sharp prominences, and may 
seriously wound some of the structures, producing a train 
of morbid signs not always of simple interpretation, death 
only revealing the true nature of the case as well as its 
cause. 
Worms in the Stomach.—These consist of several 
varieties of round as well as tape-worm, the chief of the 
former being the Ascaris marginata, or marginated round 
worm, and the Spzroptera sanguinolenta, and of the latter 
Tenia cucumerina, and more rarely Tenia cenurus, or gid 
tape-worm of the sheep. 
Symptoms.—Nausea, retching, and vomiting proceed 
‘first in order, accompanied with foetid breath, and a dry, 
troublesome, husky cough. Subsequently the bowels are 
irregular and colic ensues, with increase of the foregoing 
symptoms, especially gastric disturbance, often termina- 
ting with convulsions and death.. Some dogs exhibit a 
voracious appetite in the early stages ; notwithstanding the 
animal becomes poor and even emaciated, and towards 
the close there are signs of brain disturbance. 
Treatment.—An effective remedy consists of oil of tur- 
pentine, one or more teaspoonfuls, proportionate to the 
size and build of the dog, in combination with one to 
three ounces of pure glycerine, followed in two or three 
hours by a dose of olive oil, or the Castor Oil Mixture. 
(See Aperients.) If needful these medicines may be 
repeated in three days. . 
_Colic or Spasms, vulgarly known as Gries, is a sign 
of bowel derangement, spasmodic in nature, and unasso- 
ciated with tendency to inflammation. The Causes are 
irritants within the bowels, or the spasms may be due to. 
reflex act on arising from morbid derangement in other _ 
organs, mostly the former, the irritants being foreign 
bodies, impacted food, disease of stomach, bowels, liver, 
or other contiguous organs. Colic is often present in 
diseases induced by mineral poisons, as in /ead colic, and 
also those dependent upon animal poisons developed 
during certain diseases, as Distemper ; it is also a common
