ON FISTULA OF THE SALIVAllY DUCT. 
Dy Professor Serres, Veterinary School of Toulouse. 
M. Serres, after describing the anatomy of the parts, and 
the injury to the salivary duct (canal of Stenon), recommends 
as the best means to obliterate the fistula the application of 
a blister; the ointment to be introduced into the whole 
extent of the sinus, to secure the obliteration by changing 
the condition of the tissues, causing adhesive inflammation, 
and establishing a natural compression. But before trying 
to cure the fistula the duct must be free from obstruction 
throughout, otherwise the remedies would be useless as the 
cause of the evil would be persistent. 
In several cases this remedy, recommended by Professor 
Reynal, has not been successful, but in which the unguentuni 
egyptiacum was employed by the author with the best results, 
introduced into the sinus two or three times a day, on some 
lint, at the end of a probe. By this means fistulae, which 
resisted every other treatment, have been cured. 
This ointment acts, the author thinks, by its irritating 
properties, and also by chemically coagulating the albumen 
in the saliva. 
The.beneficial results obtained by the ung. egyptiacum in 
open synovial capsules, the author says, induced him to try 
it in salivary fistulas. 
If the fistula depends on an obstruction of the duct we 
can only attempt to carry out what has been adopted 
in human surgery by MM. Cheselden, Monro, Charles 
Bell, Morand, Desault, Duphenix, Dubois, Bayer, Vidal (de 
Cassis), Nelaton, &c., viz., to re-establish the permeability of 
the duct. This operation consists in removing the obstruction, 
destroying the cicatrix, or make an artificial canal by means 
of a trocar, and insert a leaden tube in it, one end of which is 
to terminate in the mouth, and the other at the point of the 
trocar.
