MONOMANIA IN DOMESTIC ANIMALS. 639 
remarks on the influence of the sexual passion on occasional 
aberration of mind. 
CEstromania, or the desire of sexual connexion become irre¬ 
sistible (porte jusqu’a la fureur)^ is^the only case in which the 
venereal appetite can be considered as constituting true mania 
either in man or the brute. In the male this cestromania has 
received the name of satyriasis, and in the female that of nym¬ 
phomania, or furor uterinus. 
I have never observed this kind of mania except in the mare : 
other authors profess to have seen it in the ass, the cow, the 
bitch, and the cat. I have never seen it in the male of any of 
our domestic animals, and therefore I speak of it under the 
strictly appropriate name of furor uterinus. 
It has been oftener recognized among animals than the other 
kinds of mania that have passed under consideration, and many 
writers have made mention of it in their works. The disease to 
which Paulet refers, when, quoting from Columella, he speaks of 
consumption and love madness {rage d!amour), and which con¬ 
sists in a rapid emaciation, sometimes observed in mares, when 
they may be almost seen to fall away, day by day, and perish in a 
very short space of time, was probably this furor uterinus. 
Ruel, in his translation of the Greek authors on veterinary 
medicine in 1530, refers to it, when he curiously advises that 
the mare shall be led to the border of a limpid stream, where 
she will be so aflected at seeing the state to which she is reduced, 
that her excitement will calm down and be entirely dissipated. 
Vitet places it in the list of spasmodic diseases, and calls it 
rage des jumens, produced by venereal appetite. He says that 
both the mare and the cow are subject to it. 
Aygaleng speaks of it under the name of hysteria, and places 
it in the class of neuroses, and the order vesanise. He says that 
he has seen bitches and cats attacked by it. 
Hazard, jun. speaks of it under the name of furor uterinus, in 
which a kind of insanity wgis manifest from time to time. In the 
intervals between the attacks she was perfectly manageable, but 
during the time of the eiythysm, which lasted from one to three 
days, it was dangerous to go near to her. 
Ilurtrel IXArboval treats of it under the name of nymphoma¬ 
nia, and as appearing in the mare, the cow, the bitch, and the 
cat, and being occasionally fatal to petted dogs. 
Vatel gives it the name of uteromania, and regards it as in¬ 
flammation of the brain, or, rather, the cerebellum—consequently 
an excitation of the sexual j)arts; and he speaks of some mares 
and cows that are almost always at heat, and barren. I will 
add, in this respect, that all veterinarians have observed it in cows
