form slight pustules or ulcers; on the tenth day ulcers 
showed themselves on the cornea. 
From this experiment results the sequence that ophthalmia 
produced by inoculation is invested with the same character 
and progresses as that disease does in dogs which are 
affected with blennorrhoea; with this difference, that the 
inoculated dogs did not become affected with blennorrhoea, 
the affection having stopped at the organs of vision. It 
might have been desirable that a counter experiment should 
have been made, namely, that the palpebral muco-purulent 
matter should have been placed and kept on the mucous 
membrane of the urethra, or the vagina, so as to ascertain 
whether this would produce blennorrhoea. But little impor¬ 
tance will be attached to these kind of experiments, when it 
is remembered that the results have been negative whenever 
made on the human subject. 
These first experiments having elucidated, on the one hand, 
the question concerning the direct transposition of the ure= 
thral muco-pus to the conjunctiva, it remained only to inquire 
into the probability of contagion by miasmatic influence, or 
immediate contact. 
Two dogs were selected for this experiment, one two, and 
the other four years old. Both had had the distemper, and 
were otherwise healthy. These animals were neither inocu¬ 
lated or in any other way contaminated, and were shut up for 
a fortnight in the kennel where the blennorrhagic dogs had 
sojourned ; neither the litter nor anything else which had been 
used for the affected dogs being removed from the kenneh 
As in the preceding experiment, these two dogs contracted 
ophthalmia, but in a milder form than the two of the first 
experiment. There was the weeping of the eyes, with the 
catarrhal flux, but not the ulceration of the cornea. Does 
this difference belong to the breed of the dogs, they not being 
sporting dogs ? The author does not answer this question. 
And then as to the question of miasmatic communication of 
the malady, he says that in this last experiment the contami¬ 
nation has been produced by the direct transposition of the 
blennophthalmic muco-pus from the litter to the conjunctiva, 
which might have taken place by the animals rubbing their 
eyes with their paws, or by the immediate contact of the 
impregnated straw. Twice M. Guilmot has had an opportu¬ 
nity of observing blennorrhagic ophthalmia in the dog, and that 
on a somewhat large scale, viz., in 1853 and 1856, and in both 
instances the animals belonged to sporting breeds—pointers, 
setters, retrievers, &c. .They were usually kept confined in 
kennels, which were overcrowded, and wanting in everything
