190 KENNEL DISEASES. 
The lachrymal glands may be the seat of disease, though only rarely; and 
the chief troubles of the so-called lachrymal or tear-apparatus are in the canal 
which carries off the tears. 
This canal is obstructed in what is popularly termed “ weeping eye,” in which 
the eye is constantly wet with tears that run over the cheek instead of being con- 
ducted into the nostril by the natural way. 
The canal or tear-passage in question being very narrow, a slight swelling of 
its lining membrane is sufficient to impede the passage of the tears; and this 
swelling is generally the result of a cold in the head, in which there is a like © 
condition of the lining membrane of the nostrils and throat. . 
A valve-like opening within the nose at the end of the canal is closed by 
swelling, which causes backing up of mucus or tears. Usually, however, a pre- © 
vious thickening, by “ head-colds,” causes an extension of the catarrhal inflamma- 
tion to the tear-passage and eye itself. j 
Special treatment is required for the eye when this inflammation occurs in 
consequence of a cold, though as the cause disappears it may speedily subside. 
In cases, however, where mucus collects in such quantities in the sac, which 
exists at the head of the tear-passage, as to enlarge it, then an abscess is liable 
to form; in which event lancing will be necessary. 
Camphor water and borax, as recommended for conjunctivitis, can also be 
used in this affection, though a solution composed of two grains of zinc in one 
ounce of water may be better. A 2 per cent solution of cocaine dropped into the 
nose will shorten the rhinitis and remove the epiphora — watery eye. 
DISLOCATION OF THE EYEBALL. 
Dislocation of the eyeball without much injury to the same sometimes occurs 
in man; and if reduction is speedily and skilfully effected, in many instances 
recovery is complete and the sight wholly restored. This accident with as for- 
tunate results occasionally occurs in dogs, but as a rule there are deep lacera- 
tions and the vision is destroyed. 
It usually happens while fighting, especially among bulldogs, pugs or other 
dogs that do not possess any bony arch of the eye; and in most cases the injury 
is more than mere displacement, consequently the eyeball must be removed. 
When it occurs, medical aid should be summoned; but if there must be a 
delay of more than a few minutes the owner or caretaker should make an effort 
to return the eye to its socket, employing the following method: First, let blood- 
warm water fall from the hand upon the eyeball, to remove dust or other impuri- 
ties. Then apply a little pure sweet oil, if it is at hand, but if not attainable 
without delay, the work must be done without it. With an assistant drawing the
