154 DADD'S VETERINARY MEDICINE AND SURGERY. 
given up by practitioners because they had chronic discharge ani 
swollen glands; and in ten days or a fortnight all the animals 
have recovered under the influence of nasal injections, and the 
internal administration of tonics. 
It is impossible to enter into details as to the diagnosis cf a 
great varicty of cures. I may mention, however, that the cuiable 
dischsrges set out as incurable forms of glanders may be grouped 
under six heads. 
Ist. Fetid discharges from the nostril, owing to a carious tooth 
and caries of the upper jaw. The fetor is characteristic. 
2d. Intermittent discharges from an abscess in one of the tur- 
pinated bones within the nasal chamber. The swelling of the 
nasal bones and flow of pus when the head is jerked upward are 
diagnostic. 
3d. Continuous or intermittent discharge from one or both 
nostrils, from accumulations of pus in the frontal and superior 
maxillary sinuses, indicated by the shape of the forehead and ab- 
sence of resonance on percussion. 
4th. Irregular discharge from the guttural pouches, brought 
on by exercise, or seen when an animal is made to eat hay, oats, 
4 turnip, or carrots off the ground. As the head is depressed and 
jerked, a somewhat fetid and often abundant purulent matter 
flows freely. 
5th. Discharges kept up by foreign objects in the posterior 
nares, which are continuous and fetid. 
6th. Chronic regular nasal discharge—pure ozena—dependent 
yn constitutional causes and defective management of acute ca- 
tarrh. 
All the foregoing varieties include the innumerable cases af 
suspected glanders for which animals are wrongfully destroyed. 
It is not every practitioner who can or would venture to open the 
guttural pouches, or practice dissection on the bones of the face sc 
such an extent as we find requisite in overcoming deformities and 
curing long-standing diseases. The longer these cases are treated 
by any but the right plan, the greater the difficulties encountered 
when surgical operations are determined upon ; and for this reason 
even those who would not dare to cut should always strive cor- 
rectly to diagnose the form of disease presenting itself. It is not 
necessary to refer at greater length to the method of dealing with 
the very various forms of disease above indicated.”
