piration was noisy ; there were remissions and relapses. Three 
hours after the first symptoms appeared, the head was carried 
low and inclined to the left, and there were convulsive 
movements of the neck and limbs. Soon it fell on the left 
side, became unconscious, and manifested complete insensi¬ 
bility. In this state it was killed, and at the autopsy there 
were found diffuse meningitis, hemorrhagic encephalitis, and 
in the middle lobe of the cerebellum a sclerostome, which 
had probably arrived there when an embryo. Van Heillsaw 
a three-year-old horse which was suddenly attacked with furi¬ 
ous vertigo, that lasted about a quarter of an hour. An 
autopsy revealed congestion of the brain and choroid plexus, 
while a free sclerostome was lodged in the cortical substance 
of the right hemisphere. Le Bihan found another worm of 
this kind in the occipital artery; rupture of the aneurism 
caused the death of the horse in less than ten minutes. 
Abildgaard discovered the filaria equina between the dura- 
mater and the cranial arachnoid of a horse. 
The agamous form of this worm has been encountered 
more frequently in the spermatic than in the renal arteries of 
the horse. Gurlt had already noticed the presence of these 
worms in the vaginal sheath. Aitken once saw an armed, 
sclerostome in the spermatic artery of a foal, and Baird found 
one in the testicle of a horse. Clancy met with thirteen on 
the surface of the testicle of a three-year-old horse ; the gland 
was indurated, and the envelopes infiltrated.* Brodie pub¬ 
lished a similar case. At the London Veterinary College one 
worm was found in the spermatic artery of the ass, and 
another in a funiculitis consecutive to castration. 
It is remarkable the frequency with which- these worms 
occur in the abnormal testicles of horses affected with abdomi¬ 
nal cryptorchidism. We met with a case of this kind in May, 
1883, and Simonin and Jacoulet encountered three in the space 
of two months, the testicles having undergone fibrous degen¬ 
eration. On incising the testicle of a cryptorchid which was 
normal in structure, Degive met with an armed sclerostome. 
It would be interesting to ascertain the relation in frequency 
between cryptorchidism and testicular parasitism. What is
