ribs. Such a state is often seen in young colts neglected, and I 
have traced a few of the most marked cases of consumption to it. 
The effects may not develope themselves at once; the colt may 
recover to a certain extent again his old looks and spirits for a time, 
and during the interval his breeder probably disposes of him, and 
his new owner puts him into the breaker’s hands. He is found 
what is commonly termed “ a soft horse.” The feeding does not 
produce the improvement expected; if a bay, black, or chestnut, he 
retains a rusty look; on exertion he is easily made perspire, cuts 
his legs and claps; the least change of feeding induces diarrhoea, 
when, in all probability, the animal undergoes a severe course of 
treatment for supposed derangement of the mouth and stomach. 
In Ireland, where many breeders rear colts without almost ever 
seeing them in a house, this not unfrequently occurs; the animals 
most subject to it are well bred light bays, roans, or light chestnuts, 
with tucked in elbows, small across the heart, and long legs: while 
Mr. Percivall considers that many old horses, which have even 
enjoyed the best of health, end their days either by consumption or 
glanders. 
The development of tubercles in the lungs depend on the same 
causes, as in man, probably small extravasations becoming organised, 
acting then as a foreign body, a cyst forming, and after a small 
abscess. I have been inclined to think that in many cases of 
tubercles in the horse, the minute lymphatic glands are the structure 
which take on disease; and it is in this way we have tubercles in 
the lungs in glanders, which may occur similarly in neglected 
strangles, which I have just alluded to. Calcareous or chalky 
deposits are unusual, but are represented by cheesy formations, 
which are often found. I may allude to one case in particular of 
the kind which occurred in my practice. 
A bay four-year old filly, the property of a gentleman near 
Carlow, was taken up to be trained off a bad wet pasture very thin, 
and was stable fed, well groomed, and put into work. She did not 
improve, but remained pot-bellied, haggard looking, like an animal 
of twenty, and so weak as to be almost useless. I was called in, 
and immediately suspected the teeth or stomach to be the seat of 
the derangement; but after a careful examination, found them 
sound, excepting that the teeth were almost black. The general 
emaciation was intense; the mare’s neck seemed as if only the 
ligamentum niche occupied it. The legs were dropsical, the hind 
ones particularly; one day she would eat well, and the following 
one scarcely touch a morsel of any kind. The bowels were always 
in a relaxed state, and the anus sunken in. With five minutes’ 
trotting exercise she would break out in a profuse perspiration, 
especially along the neck and shoulders, and stagger from weak¬ 
ness, while her breathing seemed much distressed. I put the mare 
under a course of tonic treatment, with plenty of nourishing food, 
but without any perceptible benefit; and after some time her owner 
gave her to me to continue any further experiments, and have the 
case under my own care. On auscultation 1 failed in detecting
