Strings; when the force of the malady is fixed on the respiratory 

 organs auscuhation of the chest right in front under the wind 

 pipe will reveal a rough, grating sound, which suggests a compli- 

 cation in the bronchial tubes; when these symptoms are develop- 

 ing the horse will have a harsh, rough cough, which apparently 

 causes no little pain and inconvenience. As a rule the faeces are 

 dry and difficult of expulsion, but when the motions begin to 

 take place, the drug pellets will frequently be covered with pieces 

 of mucous membrane, conunonl}' described by stablemen as 

 ''skin;'' the urine is mostly scanty and high colored. One very 

 marked characteristic of the disease is the extensive swelling of 

 the legs down their whole course; this is due to what is termed 

 an infiltration of the connective tissues, and as a result of this 

 swelling the horse experiences general stiffness and soreness; the 

 swelling in horses (males) not unfrequently extends, to the penis, 

 along the abdomen, to the under portion of the chest; if the 

 swellings are not reduced, we have seen cases where a mixture of 

 blood and serum appeared to ooze through the pores of the skin, 

 which, of course, clearly indicated that the effusion of fluid 

 under the skin and among the muscles and tendons was so exten- 

 sive it could not be retained, notwithstanding the swelling and 

 elasticity of the parts, and must, therefore, find an outlet some- 

 how; when the fever seems to exercise its force on the windpipe, 

 bronchial tubes and lungs, the difficulty of breathing is much 

 more marked; the nostrils are dilated and the heaving at the 

 flanks is very noticeable; moreover the horse invariably evinces a 

 desire to put his head over the box door presumably to get fresh 

 air; the nasal membrane instead of being bright red, assumes a 

 purple or leaden hue, and the secretion is generall}^ thicker and 

 more glutinous; the internal temperature will rise as high as 

 106.5 o^ i<^7 degrees, and the animal evinces more marked pros- 

 tration than ever; if the earlier developments of bronchitis are 

 not arrested the disease will progress until inflammation of the 

 proper substance of the lung tissue is established, which may be 

 discovered from the greater difficulty experienced in breathing; 

 by the various sounds observable on auscultation (listening) of 

 the chest over the sides where the ribs extend, which, of course, 

 only a properly qualified and experienced veterinary surgeon can 

 discern; however, if inflannuation of the lungs does supervene, it
