to cavil at its application to the form of disease under considera¬ 
tion. 
As to the specificity of gonorrhoea, I may remind you that the 
researches of those engaged in inquiries as to the nature of the 
disease in the human subject have not resulted in any definite 
issue. True, the statement has been made that a micrococcus has 
been detected in the discharge of gonorrheal urethritis, and in 
those of gonorrheal ophthalmia, identical in its characters from 
both sources; but there are those who assert that in urine which 
has undergone fermentative changes a micrococcus, recognized as 
M. urince , is always present; further, inquirers—MM. Lepine 
and G. Roux—have recently drawn attention to the fact that 
when cultivations of this now well-known micrococcus are intro¬ 
duced into the urethral canal of male animals, and retained there 
for a short time, a specific urethritis is established, which extends 
to the bladder and kidneys, and produces death, with reproduc¬ 
tion in large numbers of the micrococcus in the urinary products; 
and of still greater importance is the further statement that 
healthy females confined in cages with these experimentally- 
infected animals become the subjects of identical conditions, and 
die with similar urethral, cystic and renal lesions well developed. 
Now, if these altered micrococci were the actual cause of 
gonorrhoea, we should expect that in old-standing cases the blad¬ 
der and kidneys would become diseased; such, however, is never 
observed—at least in my experience. That specific urethritis in 
animals is identical with that of man is proved by the fact that 
in dogs we not infrequently see well-marked gonorrheal con¬ 
junctivitis produced by contact of the urethral discharge with the 
conjunctive. The infection is conveyed by the animal licking 
its penis, and subsequently one of the hind feet, from which the 
virus is passed to the conjunctiva in the act of scratching. Mr. 
Alex. Grey informs me that some years ago he saw a monkey— 
which had contracted the disease from handling contaminated lint 
thrown away by a sailor on board ship—with gonorrheal con¬ 
junctivitis, the infection having been conveyed to the membrane 
by the creature’s own hand. 
So far, then, we see that gonorrhoea affects the horse, the ox,
