                                    SYMPTOMS

The clinical picture presented and the degree of severity of attack in the
outbreak varied widely and ranged from cases which showed but the barest
loss of control over the hind quarters to those which were found down in the
stall, struggling violently and completely paralysed.

In the majority of cases the onset was slow and insidious. This was
very well exemplified by horse No. 70, which, for about a month before the
disease was definitely diagnosed, was seen to execute peculiar swinging move-
ments of the hind quarters. While at rest in the stall and completely undis-
turbed, the animal would swing back slowly and then suddenly becoming
conscious of its unnatural posture resume its normal position again, only to
repeat the movement after a few minutes. At this stage there was no suspi-
cion at all of any paraplegia, but later the symptoms became well marked
leaving little doubt in one's mind as to the actual condition.

In one or two cases only was the onset sudden. This was best seen in
horse No. 12 which apparently in the best of health up to the previous after-
noon was found suddenly down in the stall at night unable to get up and
exhibiting marked restlessness and excitement. The temperature at this
time was 102°. With great difficulty the animal was removed to a loose box
nearby where the next day the symptoms of nervous excitement became great-
ly aggravated and it broke through the stall twice breaking the breast bars
