forward it will not be tenable by any one, that syphilis is a 
disease peculiar to man. It is well to observe though, that 
Auzias-Turenne generally found difficulty in the first trans- 
mission of the pus from man to brute, but once an ulcer was 
formed on the latter, the pus secreted would then more 
readily induce the formation of other ulcers on the same 
animal, or others of the same species.” 
M. Delafond, in the discussion which ensued after the 
letter of General Daumas was read at the Central Society, said 
that the establishment of a certain relation between the 
maladie de coit and syphilis of man could not be avoided. Like 
in syphilis, there were pustules and a discharge from the 
vulva and penis ; like syphilis, it was contagious, it became 
constitutional ; lastly, it appeared in the last stages with much 
the same symptoms as farcy and glanders, diseases peculiar 
to the horse, but which bear some analogy with the phthisis 
which is seen at the last stage of syphilis in man. 
Delafond ’s opinion is entirely hypothetic, there is no rela- 
tion whatever that we can understand between glanders, and 
farcy, and phthisis; between phthisis and the lesions of the 
respiratory passages in syphilis in man. Ulcers on the nose, 
like cutaneous syphilitic eruptions, have been witnessed in 
the horse after the inoculation of the virus. It must be 
learned what exact relation these hold to the syphilides and 
syphilitic sores of the nose, throat, and larynx, seen in man. 
We certainly have not sufficient data to come to any weighty 
conclusion as to the nature of the malady under consideration. 
Rodloff vaguely asserts that “ a depression in the reactive 
powers of the nervous system, a proportionate disturbance 
in the functions of nutrition and reproduction, leading to 
cachexia and marasmus, constitute the characters of the 
contagious disease of the generative organs in the horse, and 
to compress the whole in a few words, it might be termed 
a nervous phthisis Like all attempted definitions, faulty, 
this is peculiarly so, because not based on a thorough know- 
ledge of the value of the words adopted, and clearly implying 
that the pathognomonic signs and characteristic organic 
lesions have not been carefully observed and wisely in- 
terpreted. 
Hering, in his usual laconic style, speaks of the organic 
lesions discovered after death as consisting, besides the local and 
superficial signs of the malady, such as ulcers, &c., of the 
the rabbit, and horse, the primary symptoms were followed by a cutaneous 
syphilide. After this, Sperino cites ail experiment, not at all conclusive, be- 
cause performed on a glandered horse. It appeared certain, however, that 
he had produced syphilitic chancres with indurated bases.
