Enlarged tuber- cular glands along the eosphagus may also press upon that organ causing obstruction and preventing the escape of gases from the stomach. Sometimes large tuberculous masses develop on the pleura. In such cases the principal symptom is a friction sound that is heard most distinctly during inspiration. If the masses are large enough they give rise to a dull sound upon percussion. In tuberculosis of the stomach and intestines, digestion is interfered with. This gives rise to poor appetite, frequently to diarrhea and sometimes to alterna- tion of diarrhea and constipation. In tuberculosis of the peritoneum or of the lining of the abdominal cavity, the lymphatic glands of the flank are often enlarged and hard. Sometimes this con- dition can be diagnosed posi- tively by a rectal examina- tion and the discovery of the hard, nodular masses. Tuberculosis of the liver does not give rise to symp- toms unless the disease is far advanced. In animals in which the post-pharyngeal lymphatic glands are enlarged, the breathing is harsh and noisy. In this condition there is sometimes difficulty in swal- lowing, and particles of chewed up food are occa- sionally expelled from the mouth, either voluntarily when it is found that they Fig. 27.
