from time of birth to prevent septic infection taking place at- 
the umbilicus. The second, a Norman, in breeding had three 
colts in succession affected, the last of which made a re¬ 
covery. This mare always had more of less mammitis subse¬ 
quent to parturition, and the colt which made the recovery 
was taken from her and placed on a mare which lost her 
colt from accidental causes. 
Again the post-mortem examination of subjects does not in¬ 
variably reveal present or previous inflammation at the um¬ 
bilical region, which would reasonably be expected if the 
umbilicus was always the point of ingress of infected material. 
1 have thought, although my clinical and pathological re¬ 
searches have not been sufficiently extended to warrant the 
assertion, that there was a difference between this suppura¬ 
tive joint disease and omphalitis proper. However, 1 will de¬ 
sist from taking up that branch of the subject in the present 
paper. 
Symptoms .—The symptoms, depending upon the localization 
of pathological lesions, are variously enumerated, of which I 
shall only give a synopsis. The premonitory symptoms are 
usually increased respirations and pulse, elevated temperature 
varying from normal to 105° F., and an injected appearance 
of the mucous membranes. Concomitant with or succeed¬ 
ing these phenomena, the urachus may be pervious, al¬ 
though it is not by any means a constant symptom. Diure¬ 
sis is present, especially during the onset of the attack, the 
urine being very light in color and ordinarily giving an acid 
reaction. The specific gravity averages about 1040 and upon 
microscopical examination reveals several fat globules and 
occasionally renal casts. Digestive irregularity is not an un¬ 
usual condition found present, manifesting itself by constipa¬ 
tion or diarrhoea. The characteristic swellings make their 
appearance in various parts of the body, usually involving the 
articulations, producing a painful arthritis. The animal may 
be found stiff and lame without any visible enlargements, 
which is likely to lead the attendant to attribute it to an injury 
incurred by the dam’s stepping on the foal. The swellings 
are round, have a doughy feel on manipulation and are in-
