served in cattle that had died of the hoove; and that it would 
have been absurd there to have searched for an old unsoundness, 
to explain a phenomenon which was mechanically produced. 
.. I then asked whether the enlargement of the lymphatic glands 
was to be considered as a cause or effect when inflammation so 
intense was manifest in the system to which they belonged. 
My decided opinion was, that their enlargement was the con¬ 
sequence of general inflammation of the respiratory organs. The 
sub-maxillary glands are sympathetically excited by the influence 
of causes far less active. 
In my opinion, chronic peripneumony, which must have been 
the unsoundness, if any here, was characterised by induration, 
grey or white, of the lungs ; by vomicae or softened tubercles; 
by adhesions organized and become solid: in a word, by that 
which attests some ancient disorganization, of which I saw 
nothing here. 4 
Beside this, I affirmed that the malady w as the fault of the 
buyer; that it was after the animal had been delivered that the 
influence of wet and cold had produced a re-action, so much 
the more dangerous, as the colt had not been accustomed to be 
exposed to the variations of the atmosphere; and that the inflam¬ 
mation which destroyed him might perhaps have yielded to 
rational treatment, which an empiric, with every wish to do 
good, was incapable of adopting; and that it was not only in 
veterinary medicine that the distinction which I endeavoured to 
establish was recognised between the lesions which indicated 
acute, and those which marked chronic affections of the chest. 
In the treatise of M. Andral on diseases of the chest, in volume 1, 
page 231, under the title “ Pleuro-pneumonia, second stage,"’ 
are the following descriptions:— 
“ 18 th Case .—Red hepatization of the superior lobe of the 
right lung; its tissue is granulated, and it sinks in water. The 
other parts of the pulmonary parenchyma present a sero-san- 
guinoous engorgement, which seems to have been effected during 
the last agonies. Albuminous membraniform concretions cover 
the pulmonary and costal pleurae, but no adhesion has taken 
place. 
“ 19 th Case .—Red hepatization of the inferior lobe of the left 
lung; sanguineous engorgement of the right lobe; albuminous 
membraniform concretions on the costal and pulmonary pleurae. 
Effusion of a glassful of red serosity in the thoracic cavity. 
“ 21 st Case. —Hepatization of the three lobes of the lungs." 
In the observations which follow the last case, M. Andral thus 
expresses himself:— 
“ When the patient entered the hospital, auscultation and per-
