cases the coexistence of colic has been noticed, only no one 
has thought of attributing the colic to the embolism or 
believed they ought to generalise the pathological phenome¬ 
non, but the case has been considered rare and exceptional. 
I will add that the idea of no more attributing colic, 
accompanied by intestinal congestion, to enteritis, has already 
cropped up several times, and some have sought to consider 
the stagnation of blood as altogether passive. M. Colin 
attempted, some years since, to attribute the intestinal con¬ 
gestions of horses to an obliteration of the portal vein, or 
compression of this vessel by great distension of some part of 
the digestive apparatus. I (Zundel) in order to explain the 
good effects of spirit of turpentine in this kind of colic, ad¬ 
mitted long ago, as a commencement of the colic, paralysis 
of the intestine and cessation of the peristaltic movements 
under the influence of an unknown cause. 
In a recent memoir on active mesenteric and intestinal 
congestions in the horse, M. Hamon has appeared to us 
equally to contest the true inflammatory character of these 
diseases. Several of my practical friends have long since, 
in conversation, expressed their disbelief in true enteritis 
occasioning intestinal congestions. 
The labours of M. Bollinger now give a solid basis to these 
opinions, and are, as I said at the commencement, capable of 
completely changing the generally admitted ideas on this 
question. On the other hand, in attributing the greater 
number of colic cases in the horse to the effects of parasites, 
these researches of M. Bollinger direct the attention of veteri¬ 
narians to the extraordinary frequency of th zStrongylus armatus , 
and call on them to take means to arrest its propagation.
