BLENN OB.RH AGIO OPHTHALMIA IN THE DOG. 
By M. Guilmot, Medecine Veterinaire du Gouvernement, &c. 
The author states that blennorrhagic ophthalmia in the 
dog has not, to his knowledge, been described in veterinary 
works, and that it is not even mentioned in the treatise on 
the maladies of dogs recently published by Professor 
Hertwig. It would thus appear that a new form of disease 
is to be added to the canine nosographia. 
Blennorrhagic ophthalmia in the dog is in every respect 
analogous to that which is observed in the human subject, 
vchen there is a transference to the conjunctiva of the 
discharge of muco-purulent matter from the diseased urethra. 
This analogy is proved by the coincidence of the phlegmasia 
of the uretha or the vagina, w 7 hich is called gonorrhoea, in 
the animal thus affected, and also by direct experiments 
made by M. Guilmot producing identical results. “ In 
following with attention,” says M. Guilmot, “ the progress 
of this form of ophthalmia, w 7 e find that after a short space 
of time, the vessels which ramify over the conjunctiva con- 
verge towards one or several points of the cornea, where they 
terminate in a small vesicle which soon opens on its summit, 
constituting a small sore (leucoma), which sometimes becomes 
ulcerous.” The convergence of the vessels has, in all the 
cases that have come under the notice of the author, com 
stantly assumed the same form, namely, the pyramidal, the 
base of which occupies the lateral inferior part of the sclero¬ 
tica, and the summit terminates towards the circumference 
of the cornea, or its central point. This description belongs, 
there is no doubt, to pterygium, wdiich becomes thus one of 
the phenomena pathognomonic of blennorrhoea in the dog, 
just as it seems to be one of the consequences of catarrhal 
ophthalmia in the human subject. It must, however, be 
observed that the appearance of pterygium in the dog is 
nothing to be surprised at, when the development of the 
semi-lunar fold of the conjunctiva towards the inner angle 
is taken into consideration, or, as it has been asserted with 
some reason, that this pathological product has its origin
