INFLUENZA, FOLLOWED BY RHEUMATISM. 671 
going on her heels, and drawing her hind legs quite under her at 
each step ; but she has considerably improved, she has got thick 
heeled shoes on both fore feet. From the 28th October until the 
present date she has continued to slightly amend ; yet she is still 
very lame. I have been using bandages of linen constantly kept 
saturated with cold water to the legs for some time, with, I think, 
good effect. The mare lies down a great deal. The knees are 
now swollen, and have been so for some days ; yet they do not 
appear tender. The mare feeds well on her warm mashes; though 
when she lies down she moans a great deal, which I should think 
is partly from habit. Whenever she rises it is with great difficulty, 
with a knuckling over of the fetlock joints; being afraid to place 
her weight on the limbs. After she moves about a little she 
places the foot to the ground more firmly. On examining the legs 
we find a great deal of thickening around each fetlock joint, and 
about the tendon. The near fore fetlock is not, however, painful to 
pressure; but the off fore fetlock is extremely sensitive, the 
slightest pressure about the joint giving great pain. I intend now 
to try the effect of blisters to the joints. 
Remarks on the foregoing case. 
I consider this case to be one of those rheumatic affections occa- 
sionally met with in the horse. Mr. Castley directed attention to 
it under the head of metastasis of inflammation. Mr. Percivall has 
written upon it, and considers it to be rheumatism. The latter is, 
I think, the proper account of it ; and if we consider the general 
features of the disease and its erratic character, we shall find it in 
all respects analagous to rheumatism in man. The pleura is com- 
posed of white inelastic fibres and cellular tissue, which accounts 
for the great pain present in pleurisy, the parts not allowing of 
expansion when under inflammation, the nerves and fibrous tissue 
being thereby compressed. We know that there is the greatest 
sympathy existing between parts of the same structural formation 
although distant from one another, examples of which may be shewn 
in many instances. How often in pneumonia and affections of the 
mucous membranes do we find that the smallest dose of aloes will 
purge immoderately. How careful and prudent is the veterinary 
practitioner obliged to be in this respect. Sometimes we find 
inflammation of the laminae a sequel of inflammation of the lungs ; 
but T believe in these cases, if they were properly investigated, 
they would be found to arise after disease of the pleura or peri- 
cardium, or that those parts were involved, parts similar in structure 
to the fibres of the sensitive laminae. 
In pericarditis, too, how frequently has lameness suddenly
