galls. At the beginning and in young subjects, rest, turning out to pas~ 
ture or moderate exercise, astringent compresses, flannel bandages are 
generally sufficient. Later on, blisters, mercurial ointment, that of bichro-. 
mate of potash or lines, fine points or needles firing are indicated. : 
Dard has recommended the puncture with the: 
bistouri (1831) and Macheras also ; the latter in- 
troduced in large windgalls, a “tent of cotton.” 
At the Alfort Clinic, Bouley and Prudhomme have-. 
resorted to puncture with blistering application. | 
In 1844, Rey associated the puncture with the. 
alcoholized injection, a friction of iodide of lead. 
ointment and pressure with splints. Puncture is 
harmless only when performed antiseptically. It 
must always be followed by fine points firing or: 
by iodined injections. Leblanc, Barry, Rey,. 
Festal, Porel, Liard, Dupon, Reul have had suc- 
cess with it. The unfortunate results of Bouley,. 
Lafosse and Verrier can be explained only by the:. 
want of complete aseptic measures. 
When windgalls are old, have resisted firing __

If synovectomy is to be attempted, it must be only with the greatest at--

Chronic synovitis of the great sesamoid is often accompanied with. 
lesions of tendons (Barrier) or of the sesamoid bones, analogous to those of 
the plantar aponeurosis and small sesamoid sheath in navicular disease: 
(Brauell, Moller, Marcher). Ordinarily in these cases, both bones are dis-: 
eased ; though sometimes only one. Brauell has found the flexor tendons: |" 
united to the bones. According to Marcher, cauterization may give relief 
in those cases. 
Dropsy of the small sesamoid sheath is rare. Its treatment is that of 
wavicular disease.
