ders, may be, and perhaps often is, communicated by the fluids 
that are in circulation. 
This change, however, is far from uniformly taking place. Dur- 
ing the present year we have not had a single proof of the possibi- 
lity of this contagion. We have taken five sound horses, and we 
have placed them in the same stable with five that were evidently 
glandered. Not one of the previously sound horses has taken 
the infection. Notwithstanding, however, the doubts which we 
have been compelled to avow of the contagious properties of this 
disease in a chronic state, we heartily approve of the measures 
of precaution that have been adopted. We always counsel the 
isolation and the sequestration of glandered horses. A malady 
which is so susceptible of change of form, and consequently of 
properties, ought in practice to be considered as contagious by 
every veterinary practitioner. 
Diseases of the Chest. 
The antiphlogistic and revulsive treatment is almost exclusively 
employed, and generally with success, in acute inflammation of 
the lungs and the pleura. Among the numerous cases that have 
been brought under our notice there were three that, on account 
of the peculiar character which they assumed, deserve especial 
mention. 
In one case pneumonia, perfectly characterized in the remain- 
der of its course both by the usual exterior signs and by those 
which auscultation furnishes, was complicated with certain vio- 
lent ataxic (irregular or disordered) symptoms. The disease as- 
sumed a singular vertiginous character. The horse threw him- 
self violently on the ground, and tore his flanks with his teeth. 
We thought that this was complicated with cerebral inflamma- 
tion. Death exhibited lesions of acute pneumonia, which occu- 
pied half of each of the lungs. 
In the second case, the horse was brought to the hospital with 
all the most violent exterior characters of acute pneumonia. There 
was interrupted and accelerated motion of the flanks — a plaintive 
sound in respiration — a reddish discharge from nostril — a yellow- 
ish red injection of the conjunctiva — the pulse full and hard. All 
these symptoms existed, and very attentive auscultation permitted 
us to perceive the respiratory murmur loud and sonorous through 
the whole extent of the thorax. The resonance was remarkable 
on whichever side we sounded him, and through the whole 
extent of the walls of the chest. This absence of the ordinary 
symptoms, so positive, which auscultation affords in acute in- 
flammation of the lungs, weakened the diagnosis to which we 
might be conducted by the exterior appearances, especially
