thickened, lardaceous, and hollowed here and there with suppu¬ 
rative centers. These lesions exist also on the internal plate of 
the hone and can be followed to the ethmoid, the volutes of this 
hone forming amass of gangrenous purulent substance, with an 
infectious odor, with loose pieces of diseased bone ; the cribri¬ 
form plate is also diseased, and it is through it that the inflam¬ 
mation has reached the encephalic envelope. The dura mater is 
very adherent to the bones ; the two layers of the arachnoid are 
inflamed, adherent together in numerous places, and show a 
whitish purulent serous infiltration, extending into the meshes of 
the pia mater. The lateral ventricles contain a puriform liquid. 
Beyond the bulb, the cavity of the arachnoid shows only little 
marks of the inflamed condition of the cranian meninges, hut 
the central canal of the marrow contains drops of pus analogous 
to that of the lateral ventricles and much thickened .—Archives

ABSCESSES OF THE MESENTERY OF THE SMALL INTESTINES- 
TERMITTENT COLICS.

By Mr. Lahogue. 
Two cases are reported by Mi-. Lahogue, which, while they 
throw but little light on the diagnosis of the disease, are no less 
interesting to the point of view of the etiology of those intermit¬ 
tent colics so commonly fatal in horses. The first case is that of 
a mare which had been ailing for two months past without pre¬ 
senting any special symptoms. The history is that she had fre¬ 
quently suffered with light colics ; that her appetite was irregular 
and she had lost considerable flesh. Under a mild treatment of lax¬ 
ative and careful diet, she seemed to improve ; but some days later 
was taken with more severe symptoms, which were somewhat 
relieved, and after a third attack she died. On post mortem the 
abdomen is found containing a large quantity of liquid, of wine 
color, mixed with purulent matters; the intestines are congested, 
especially the small intestine, which is almost black in its wdiole
