remarkable agent, one which promises to be a sister com¬ 
panion to chloroform in alleviating the ills to which flesh is 
heir. I hope I may be fortunate enough to arouse the atten¬ 
tion of my professional brethren to the investigation of the 
chemical action of remedies on the blood, and thereby, perhaps, 
lead on to a more rational and satisfactory mode of treating 
some diseases, which in time to come, I believe, will be 
attacked directly through the blood itself,— Head before tie

SPASMODIC COLIC IN THE HORSE. 
By M. Bollinger. Translated by Alexander S. Rolls, M.R.C.Y.S., 
Arundel. 
In the Recueil de Medecine Veterinaire for May and June, 
1871, M. Auguste Zundell, of Mulhouse, in his Veterinary 
Chronicle of Germany , reviews a recent work of M. Bol¬ 
linger, Professor at the Veterinary School of Zurich, which 
he says tf<r seems to promise to overturn all our knowledge of 
one of the most frequent diseases of the horse, i. e. colic. 
Prof. Bollinger shows that the intestinal congestion accom¬ 
panying the majority of these cases is due to the stoppage of 
an embolism in the ramifications of the anterior mesenteric 
artery, which embolism is due to a' verminous aneurism 
found in the large trunk of this artery, near its origin from 
the posterior aorta. 
The extraordinary frequency of these aneurisms in the 
horse has been recognised, first by Hering, and since by 
Rigot, Rayer, Bruckmiiller, and Bollinger. The result of 
these researches is that the number of horses having these 
arterial aneurisms is greater than those without, and often 
there are several in the same animal. M. Bollinger admits 
that in 200 horses there are 168 aneurisms, of which 153 are 
of the anterior mesenteric, 4 of the coeliac arcis, 3 of the 
renal artery, and 2 of the posterior aorta. In 100 adult 
horses you find 50 to 54 having an aneurism of the mesenteric 
arteries. Morgagni, Ruysch, Hodgson, Grene, had already 
attributed these aneurisms to the action of the Strongylus 
armatus found so frequently in the cavity of the dilated vessel.
