PROGRESS OF VETERINARY SCIENCE AND ART. 91 
3. From its beginning to its very 
highest stage, as a rule, no fever is 
witnessed. 
4. In mares there is often wagging 
of the tail and frequent attempts to 
urinate. 
5. From the vulva flows at first a 
slight amount of mucus, which peri- 
odically increases in quantity, and 
soon becomes very thick, and after- 
wards purulent, offensive, and of a 
reddish-yellow colour, and on drying 
forms yellowish-brown scabs. 
6. Unequal looseness and redness, 
with subsequent pallor and dirty 
reddish or yellowish colour of the 
mucous membrane of the vagina, 
with a few visible veins on the same. 
7. Great swelling of the vulva, 
associated with heat at first, which 
disappears later, and as the tume- 
faction subsides puckered-up folds 
of the skin around keep the vulva 
open and induce a protrusion of the 
clitoris. 
8. Vesicles, containing a yellow- 
ish fluid, on the mucous membrane 
and external surface of the vulva, 
which soon pass into ulcers; these 
heal in from a fortnight to three 
weeks, leaving white, brightly re- 
flecting scars behind them. 
9. In stallions, nodules, small 
pellucid bladders, and little ulcers, 
appear in moderate numbers on the 
penis ; there is great swelling of the 
prepuce and scrotum. 
10. Both stallions and mares in 
drawing forwards the hind feet often 
trip up, and in standing change 
about on one or more limbs, 
11. Heaviness, faltering in mo- 
tion, a blunt state of all the senses. 
12. Flat, round, circumscribed boils 
in the skin, of the size of a sixpence 
to that of the surface of the hand, 
and the hairs erect on the boils. 
13. Sooner or later swelling of the 
inguinal glands and some of the lym- 
phatic vessels of the hind limbs. 
14. Debility of the hind extremi- 
ties, lameness in either one or the 
other of them. Paralysis of various 
parts, of the ears, of lips, especially 
of the lumbar region. 
3. There is often a moderate 
amount of fever at the commence- 
ment. 
4. The same appearances, but not 
always so striking. 
5. In most mares there is a slight 
and regular flow of white, tenacious 
mucus observable, without increase 
in consequence of severity of other 
symptoms. 
6. Equal darkish redness and 
looseness of the mucous membrane 
of the vagina, and in a short time 
regular disappearance of this con- 
dition without observable vascu- 
larity of the membrane. 
7. Moderate swelling, with or with- 
out small wrinkles, so that the vulva 
is not kept open and the clitoris 
does not protrude. 
8. Small elevations or yellowish 
vesicles, which either soon dry and, 
on falling off, leave behind red or 
whitish scars, or they may pass into 
the state of ulcers; in the latter 
case, from the appearance of the 
vesicles to the ulcers scabbing, only 
from eight to ten days elapse. 
9. The same appearances, but 
usually more and larger bladders, 
and the swelling more speedily sub- 
sides. 
10. These symptoms are entirely 
absent, and should they exist they 
are very slight and of short duration. 
11. The animals lose none of their 
wonted vigour and energy. 
12. No boils, and the coat is 
smooth. 
13. These swellings rarely occur, 
and soon disappear. 
14. These accidents never occur.
