elude that pultaceous substances are always submitted to this se¬ 
cond grinding, and that the dangerous effects of certain aliments 
arise simply from the facility with which they pass into a state of 
fermentation.” 
We have also seen bran, from its disposition to ferment, and 
from its being given in too large quantities, produce very serious 
meteorization. 
M. Volley, V.S. at Aubigny, had a case of hoove in a cow, 
which was plainly traced to two pins that had entered the paunch 
with the food, and had penetrated through that portion of its parie- 
tes which abutted on the diaphragm, and also the diaphragm itself. 
She had had constant attacks of hoove, which had vielded occasion- 
^ ' •/ 
ally to the administration of alkaline medicines, and enemas, and 
the employment of panadas, and to the habitual use of boiled legu¬ 
minous seeds as food. The animal evidently suffered very great 
pain occasionally, and seemed to resist as much as she could the 
return of the food for rumination. At length some degree of dis¬ 
tention of the stomach followed every meal, from the fermentation 
of the imperfectly ruminated food. Ultimately the veterinary sur¬ 
geon prevailed on the owner to have the animal slaughtered. On 
post-mortem examination, he found that the interior and anterior 
wall of the paunch was pierced, in a direction from within out¬ 
wards, by two brass pins, which pierced also the diaphragm, and 
united these two organs together, and prevented that contraction of 
them which was necessary for the ascension of the pellet of food 
to undergo the process of rumination. 
In a memoir that was presented to the Royal Society of Agricul¬ 
ture, by M. Tressigner, in 1824, was related the case of a 3 mung calf 
that died from distention of the paunch by means of a hair ball, 
which was found in an unnatural depression, near the opening of 
the oesophagus into the rumen, in such a manner as to hinder the 
return of the food to the mouth for the purpose of rumination. The 
only symptoms by which this singular affection was accompanied 
were extraordinary thinness, and frequent hoove, so that the actual 
cause was not suspected for a moment. If it could be anatomically 
and physiologically demonstrated that the paunch was merely an 
appendix to the abomasum or true stomach of ruminants—that it is 
an organ in which the aliments are submitted to a certain modifi¬ 
cation which prepares them for digestion—if experience and obser¬ 
vation had proved that many causes could suddenly disturb the 
functions of this viscus, and produce, among other effects, a con¬ 
siderable disengagement of gas, which enormously distends this 
stomach, this disease would be truly a species of indigestion: but 
it is erroneous to say, when speaking of meteorization of the paunch, 
that where there is no digestion ever going forward, there can, pro-
