but it may be coincident vvitli lesions of the spleen, kidneys and 
liver. 
Mesenteric Form .—It is only at an advanced period that we 
might be led to suspect this form. The disease when the en¬ 
larged glands comprising the neighboring organs cause ascites or 
jaundice, or they are associated with some other external lesion 
of the diathesis that we would be likely to examine the abdomen. 
Percussion nor palpation may not give us any special information 
in our large domestic animals, but an exploration per rectum 
might disclose the presence of a large, irregular, hard tumor, 
which unites all the organs in the neighborhood. 
In dogs in which the symptoms show a growing dulness, 
tendency to sleep, becoming insensible to the voice, lying down 
all day, it being necessary to strike them to make them rise, walk¬ 
ing with head low, the jaws open (mouth open), tongue hanging, 
tail between the legs, panting. If these symptoms persist for sev¬ 
eral weeks, with ascites, no fear, no pain, and palpation, permits 
us to make out in the superior parts of the abdomen a mass hard 
and mammilated. 
Bronchial form .—As we might easily imagine, the hypertrophy 
of the bronchial ganglia, situated in the anterior mediastina, in 
the vicinity of the heart, large arterial vessels, veins and lympha¬ 
tics converging toward them with the bronchial tubes, oesophagus, 
pneumogastric and recurrent nerves liable to be pressed upon, is 
apt to cause varied and grave accidents. The respiration becomes 
accelerated, interrupted, with rapid panting, dry paroxysmal cough, 
analagous to that in heaves, but without the stethoscopic signs of 
that disease at a later period ; they cannot go at a rapid pace nor 
draw heavy loads, they commence to whistle, separate their front 
legs, head and neck extended, nostrils widely distended, the mucous 
membrane becomes cyanotic, and the patient is in imminent danger 
of death by asphyxia. Tracheotomy in this case would not give 
good results unless the dyspnoea was the result of compression of 
the recurrent nerve. In cases where the bronchial tubes or 
trachea were compressed by the tumors, the operation would not 
relieve. 
The compression of the oesophagus may cause rejection of the
