remain uninjured. On the left side is a smaller but similar 
tumour, which, by uniting with the right side tumour, forms 
a canal through which the posterior aorta is seen passing. 
Similar osseous growths extend as far forwards as the seventh 
dorsal vertebra, making in places the same sort of supple¬ 
mentary canal. The intervertebral discs in the loins are partly 
destroyed in some places, while in others they exhibit a yel- 
reen tint. False anchyloses, likewise, are commencing, 
marrow is sound throughout.

ES INTO A DISEASE OF THE HORSE AS 
YET BUT LITTLE KNOWN. 
By 0 . Delafond, 
Professor of Pathology at the National Veterinary School, Alfort. 
Under the above anonyme is presented to us a disease of 
grave character (une maladie grave) yet but little known, 
which M. Delafond believes to have its origin in some im¬ 
portant modification in the organic elements of the blood. The 
disease presents itself under two forms, types, or stages. The 
first form M. Delafond has been in the habit of describing in 
his lectures under the appellation of acute enteritis with alter¬ 
ation of the bloody this alteration being very remarkable before 
the disease even declares itself, while there supervenes an 
inflammation of the mucous lining of the intestinal canal. 
The second stage or form, M. Delafond has named anaemia , 
or Hydro-cemia, appellations generally adopted by veteri¬ 
narians. The disease is no new one. For these fifteen or 
twenty years past it has been known to destroy great numbers 
of the farmers’ horses in the country, particularly in parts 
where artificial productions constituted the principal provender. 
A variety of circumstances influence the progress, intensity, 
and termination of the disease, though in its nature it has 
undergone no change whatever. 
In its ACUTE form, the approach of the disease is recog¬ 
nised by a yellowish-reddening of the conjunctives, which 
sometimes shew reddish brown spots, that vanish shortly after¬ 
wards, or, may be, continue their existence; the pulse is full 
and strong; the hair draws out easily, and the skin is warmer
