REVIEW—CATTLE PATHOLOGY. 
or even enteritis, is the cause of the indigestion, which is only 
secondary. 
Among the most constant symptoms of inflammation of the gas¬ 
trointestinal mucous membrane is the loss of appetite in all animals, 
and the cessation of rumination in the ox. We ought to consider 
this phenomena as a sage precaution of nature, which thus pre¬ 
vents the ingestion of aliments which the stomach is not then sus¬ 
ceptible of converting into chyme; for observation proves that even 
during convalescence the least wandering from a proper regime 
will produce the most fatal results. 
If the inflammation is intense, the tongue seems to be contrac- 
ed, and is evidently straighter and more rounded; the papillae 
which cover it become erect and injected; the tongue itself is red 
towards its point, and also at its edges. 
In certain intense cases of gastritis, and in some serious affec¬ 
tions of the paunch or the abomasum, the duodenum and the liver 
participate in the inflammation, and the tongue is yellow or green. 
This colouring sometimes extends to all the visible mucous mem¬ 
branes. 
Vomiting, which can only take place when there has been primi¬ 
tive or secondary affection of the stomachs, denotes almost always 
a very intense inflammation, either most commonly continued 
from the abomasum and the pylorus, or also from the oesophagean 
canal. Thus it is constant in chronic gastro-enteritis, and rare in 
acute. Nevertheless, if one part of the food is vomited, and the 
other passes from the abomasum into the duodenum, it is to be 
presumed that the seat of then inflammation principally exists in 
the abomasum. 
The diminution and even the cessation of the secretion of milk, 
constant in cows labouring under gastritis, is only the result of the 
displacement of the vital action of the secretory organ, in conse¬ 
quence of the violent inflammation which attacks the mucous mem¬ 
brane of the digestive organs. 
Finally, the digestive sympathies exercise so great a power in 
the living economy, especially in a state of disease, that we shall 
see inflammation of these viscera producing either a state of lassi¬ 
tude or of want of power, or of utter prostration of strength, ac¬ 
cording to the greater or less degree of their intensity. 
From that which I am about to state, it will appear that inflam¬ 
mation of the gastro-intestinal mucous membrane, like every other 
kind of inflammation, may present itself Avith different degrees of 
intensity; that it is especially modified by some individual nervous 
power, and by the greater or less degree of particular and special 
animal heat. Thus it is less acute among cachectic animals 
than among those of a lymphatic temperament and feeble vital 
energy.
