chyma of the lungs is consecutive to the interlobular exuda¬ 
tion. This would in some way account for the formidable 
nature of the malady, and the reason that it does not yield 
to antiphlogistic treatment equally with simple pneumonia. 
The exudation is favoured by the greater freedom possessed 
by the lungs, consequent upon the increased capacity of the 
chest; the collapsed rumen no longer maintaining the 
diaphragm in its proper position. For the last few years 
a decrease has been observed in the number of cases in 
the distilleries. This the author attributes to the introduc¬ 
tion of mangel-wurzel as an article of diet. This root, 
besides containing different elements of nutrition, requires 
the concurrence of the whole digestive apparatus to convert 
it into nutriment. In the case of beasts which are fattened 
in the rich pastures of Holland and elsewhere, the cause, 
in the opinion of the author, is similar. The tender plants 
which are taken in large quantities, in almost a pulpy state, 
relax the system, and thus predispose to the invasion of the 
malady, which makes its appearance just when the animals 
begin to acquire flesh. 
The variations of the temperature have also great influ¬ 
ence, by producing more or less sudden modifications in the 
function of the skin. A cold, damp air is always hurtful 
to cattle in the field or pasture. 
The author endeavours to establish that pleuro-pneumonia 
is the immediate result of causes which are the work of man, 
not of nature. If this is founded on truth, those animals 
which are placed in the opposite circumstances ought to 
escape. This is just what takes place; to wit, the 
arid plains, mountainous countries, and all districts where 
rich pastures are wanting and distilleries rare, there pleuro¬ 
pneumonia is almost unknown. This, at least, is the result 
of observations made in Belgium, and no doubt the same holds 
good in other countries.. The question might be asked, how 
is it that in the same locality one cultivator’s stock is deci¬ 
mated, while that of another escapes ? To account for this 
fact, the condition of the animals must be considered when 
they are put into the pasture, as well as their age, breed, and 
conformation. If milch cows, whether they are in full milk 
or in a state of gestation, all of which conditions are for or 
against the malady. As to the age, young and growing 
animals are less subject than adults; for this reason, that 
the excess of nutriment goes to the growth. Great im¬ 
portance is to be attached to conformation. An animal 
which is well ribbed, has a broad back and capacious chest, 
with well-developed frame, will resist an attack of pleuro-
