ON CORYZA AND NASAL GLEET IN THE HORSE. 103 
pest of the equine race. This other disease, glanders, is princi¬ 
pally characterized by a defluxion from the nose, and inflamma¬ 
tion and ulceration of the Schneiderian membrane. How shall 
we distinguish the one from the other ? Not always with cer¬ 
tainty ; but there are landmarks which will not often mislead us. 
We shall understand them better by-and-by, when we have 
treated of glanders; but we must say something about them even 
now, for the life of a valuable animal may be at stake, or perhaps 
the safety of a whole stud. 
The discharge of nasal gleet is of a mucous character, and not 
very adherent ; the discharge of glanders is more pellucid and 
sticky; and yet sometimes, when the discharge of nasal gleet is 
small in quantity, it dries about the edge of the nostril, and gives 
an appearance of stickiness, difficult, very difficult to be distin¬ 
guished from that of glanders, and requiring all our “ tact, talent, 
and discrimination.” 
The discharge of nasal gleet is always more or less irregular ; 
that of glanders is constant. The first is of an uncertain hue, 
white, yellow, brown ; the other is usually pellucid. The first is 
free from smell; the second may be so, but it often stinks abo¬ 
minably. 
The submaxillary glands are not always affected in nasal gleet, 
but generally they are a little soft, more enlarged, somewhat ten¬ 
der, and situated towards the centre of the channel. In glanders 
the glands are harder, not tender, nearer the jaw, and often ad¬ 
herent to it. 
The membrane of the nose in nasal gleet is red, although in¬ 
deed with variable intensity ; but that of the glandered horse is 
pale or livid. If the membrane is abraded in nasal catarrh, the 
abrasions run in lines, and they are superficial; the edges are 
irregular and ragged. If the chancres of glanders run in lines, 
yet the ulcers are detached, rounded, deep, and the edges ele¬ 
vated. Attention to these distinctions will preserve you from ma¬ 
terial error. I will suppose you to be consulted respecting a case 
of nasal catarrh. Be very guarded in your prognosis, and espe¬ 
cially with reference to glanders. There may be little or no 
doubt in your mind with regard to the nature of the disease ; yet 
be cautious. Remember that every disease that gradually im¬ 
pairs the strength of the constitution, may run on to glanders, 
and much more a disease of that membrane which is the very 
seat of glanders. You will guard yourself by a hint of this, that, 
should the worst happen, it may not be imputed to you, that, 
where so much might be at stake, you had mistaken the com¬ 
plaint. 
You arc entering on the remedial treatment of it. It is one of
