berger and Frohner). ' By’the combination of:these means, a rapid im- 
provement is habitually obtained; sometimes in less than 15 days 
the lameness disappéars. If dropsy of the serous remains, firing generally 
removes it. That which renders the prognosis serious is the . peculiar 
moving about character of the disease, which involves other serous. 
When one first lameness is reliéved, and the animal is ready to.-resume 
work, another synovial may be affected’ and'the disease reappears in it 
with all its acute characters. However, cases similar to that of Trasbot, 
where the lameness lasted eleven months, are absolutely exceptional. 
: If the severity of the inflammatory phenomena indicates the possibility 
of suppuration, aspiration followed by phenicated mess may prevent 
the ulceration of the synovial.

AN 
CHRONIC SYNOVITIS—DROPSIES. 
Common in horses; they are due to the same causes as hydarthrosis 
are. They sometimes follow acute inflammation of serous, or again and 
most frequently under the influence of excessive work. Most of the 
animals used for a long time to heavy work have on their legs windgalls or 
thoroughpins. If the accumulation of synovia in tendinous sheaths does 
not at first disturb the regularity of the movements, there is a moment 
when continually increasing it gives rise to lameness. 
In the places where itis less protected, the synovial sac protrudes.’ 
The dilatations, whose seat is known for each serous, always insure 
the diagnosis. According to the length of time of the affection, 
they are soft, fluctuating, or again indurated, calcified. The ordinary 
clinical characters of these dropsies may be modified by the partitioning 
of the cavity ; the dropsy is unevenly marked in the various culs de sac, 
sometimes even scarcely in one of them. The aspect of their fluid 
varies very much: often clear and serous at first, it is generally thick and 
dark in old dropsies. Sometimes riziform granula are found in them. 
By regular training, a moderate work proportionate to the organic 
resistance, by douches, massage, compression, one may, in numerous 
instances, prevent the dropsies of tendinous synovials. When they are 
recent, it is again the same means that are to be used, adding to them 
rest in a box-stall or in the field. Purgatives and diuretics are useless. 
Later, when the tumors have already reached a certain size, when the 
perisynovial tissues are indurated, more active treatment must be resorted 
to: blistering, strong liniments, cantharided collodion, sublimated collo- 
dion and a mass of more or less complicated preparations can be used; 
‘but their action is less powerful and less certain than firing under any of
