by the application of a blister round the wound — his aim being 
to create a tumefaction of the parts, and thus establish a natural 
and permanent compression of the fistula. The cure was as rapid 
in this as in the other, hence the author has been led to con- 
clude, contrary to the opinion of many veterinary surgeons, 
that wounds in the parotid duct are not very dangerous, and that 
the persistence of fistula, inflammation, suppuration and gangrene 
of the parotid arises from the use of plugs, pledgets, sutures, 
ligatures, cauterizations, &c. all of which the author unreservedly 
condemns. 
In pursuing his experiments, M. Raynal has proceeded in the 
following manner: he made a longitudinal incision of about fif- 
teen millimetres, or nearly two inches in extent, in the parotidean 
canal of three horses. Two of these animals were left to the care 
of nature. The flow of saliva increased until about the seven- 
teenth day, after which time it diminished, and had entirely 
ceased about the twenty-fifth or twenty-seventh day. He applied 
a blister to the third horse, the effects of which were seconded by 
the approach of the heated iron. Considerable swelling super- 
vened. The flow of saliva speedily decreased, and ceased entirely 
about the fourteenth day. The same experiments have been seve- 
ral times repeated without any variation in the results, and M. 
Raynal concludes that, when the salivary fistulae are occasioned 
by a sharp instrument, recourse should be had to this mode of 
treatment. A post-mortem examination of three of the horses 
experimented on proved that the cicatrization of the wound had 
not caused the obliteration of the canal. 
M. Raynal has added to his communication on salivary fistulae 
two cases of caries of the third sternal rib in the horse ; in both 
of them the removal of the diseased part was effected with success. 
This gentleman’s communications on fistulae of the parotidean 
canal are exceedingly valuable. The practical facts contained in 
them, united with those already known, will contribute materially 
towards the solution of a very important therapeutical question. 
Your committee think that M. Raynal should have honourable 
mention made of him in the report. 
A collection of six cases is addressed to you by M. Eleouet, 
veterinary surgeon in the district of Morlaix (Finistere), secre- 
tary to the Agricultural Society of that place, and perpetual se- 
cretary to the Veterinary Society of the department of Finistere. 
Three of these cases relate to the extirpation of the globe of 
the eye practised with success on dogs. The mode of operating 
adopted by M. Eleouet is simple, the execution of the operation 
easy and prompt, and there is no danger. More than twenty 
years ago, when we were professors of clinical medicine at the
