arachnoid and the external face of the pia mater. In conclusion, 
Mr. Scoffie says : (i) Stallions ought to be carefully examined, 
not only in relation to the lesions and blemishes that may be 
transmitted, but also with the object of detecting cardiac lesions 
or others which may endanger their lives ; (2) Copulation must 
not be allowed during the process of digestion, which is specially 
favorable to vascular ruptures on account of the pre-existing 
bloody hypertension.— (Remie Veterinaire^ 
Clinical Observations. —Continuing a habit seldom fol¬ 
lowed by American veterinarians, Prof. Labat, of Toulouse, 
related these interesting practical cases in the Revtie Veteri- 
naire : 
(1) Cysts of the Spermatic Cord. —This horse had been suc¬ 
cessfully castrated and three months and a half after was suffer¬ 
ing with a large swelling of the scrotum and inguinal region of 
the right side. By careful examination of the parts, condition 
of the cord by rectal exploration, a diagnosis of champignon 
was at first entertained, though the mobility of the mass, its 
puffy consistency, etc., might suggest another lesion—perhaps 
an epiplocele. At any rate, surgical interference was decided 
upon and the animal submitted to operation. The manipulations 
revealed that it was the spermatic cord which was diseased, but 
instead of finding the ordinary champignon, it was an ovoid 
mass, the size of a turkey’s egg, in which the cord—soft, puffy 
and infiltrated—contained several cysts of various dimensions, 
one as big as an almond, another the size of a large marble, two 
others as big as peas. These cysts were lodged in the interstitial 
connective tissue, their membrane or envelope was thin and 
white, their inner surface smooth and their liquid contents citrine 
and clear. Recovery of the animal followed rapidly. 
(2) Chronic Inguinal Epiplocele.^ folloiving Castration .— 
This horse was castrated six months ago, and the wounds of the 
operation healed well with the exception that on the left side 
there remained a little fistulous tract, from which pus was ooz¬ 
ing. A swelling of the region soon occurred, and the owner ap¬ 
plied to the school of Toulouse for advice. The left inguinal 
region is occupied by an ovoid tumor, painless, not oedematous, 
in the centre of which is a fistula. Rectal exploration shows 
the superior inguinal canal dilated, not lacerated, with a thick 
cord running through it. This is evidently adherent to the 
bottom of the cicatricial tissue and the skin. Chronic inguinal 
hernia is diagnosticated and this is due to a portion of the great 
omentum. The hernia cannot be reduced and the animal is
