which this disease generally manifests itself as a unilateral 
pneumonia and pleuro-pneumonia. Fortunately the bilateral 
cases were in the minority. As long as the morbidity was con¬ 
fined to one lobe, and even when two-thirds or more became in¬ 
durated, recovery could be confidently relied upon, but the bilat¬ 
eral cases generally declined into hydrothorax. 
Age, sex, breed, locality and nutriment had but little influence 
upon susceptibility. 
Symptoms. —The chills usually heralding the sporadic lung 
fever were scarcely ever observed. Anorexia and want of spirit 
were the chief symptoms for two or three days, while the respira¬ 
tion and circulation remained almost tranquil; at this stage, how¬ 
ever, the thermometer invariably indicated the disturbance going on 
in the system with 103°-4° and sometimes rising to 105 o -7° in 
twenty-four to forty-eight hours, though only when the disease 
reached its highest pyretic point. The short dry, sometimes soft 
cough which was heard in the beginning, soon grew less, or changed 
into a mere attempt until crisis set in. The Schneiderian mem¬ 
brane presented a hypersemic aspect. A thin, yellowish, or rust- 
colored discharge emanated from the nose, very often of a flocu- 
lated character; this discharge was generally visible between the 
third and seventh day, and then only periodically; occasionally 
it was expectorated. Already at the outset auscultation and per¬ 
cussion furnished reliable evidence as to which lobe, and to what 
extent it was affected. But if the attack was located in the cen¬ 
tral portion of the lungs, as some authors explain it, or that the 
exudation had not yet taken place, (which theory is just as plaus¬ 
ible) the uncertainty continued one or two days longer, and in 
rare exceptions four or five days, when the vesicular murmurs in 
the afflicted portion either diminished or ceased entirely, or were 
succeeded by a brushing noise “ fremitus ” corresponding in time 
with the movements of either the lungs or heart. In the adja¬ 
cent parts the respiration was indistinct at one time, tubular at 
another, and in the portions which were still intact it was supple¬ 
mentary. The complication with pleuritis pericarditis and the 
various changes and conditions of the parenchimatose infiltra¬ 
tions causes, as is known, characteristic acoustic sounds, of which
