Veterinary obstetrics, including the diseases of breeding animals and of the new-born . ed and her general health well guarded. Nymphomania and cysts in the ovaries of the smaller animalsare not common. In the foregoing pages, Hess records instancesin the sow and goat. We have observed nymphomania in a sowwithout determining the cause. We have also seen a nympho-maniac bitch, which was castrated in our clinic and in whichboth ovaries were the seat of enormous cysts, as shown in Fig. 19. The diagnosis of cystic ovarian degeneration in the smalleranimals can only be made by the subjective symptoms of nym-phomania, to be verified by laparatomy and direct examinationof the ovaries. The best treatment is castration, though, in thebitch and sow, it is indeed quite possible, in cases where thepedigree renders the patient highly valuable for breeding pur-poses, to crush or puncture the cysts and return the ovaries intothe abdomen or, if only one gland is involved, it may be removedand the sound one retained, in order that the animal may breed.

In aged females, senile ovarian atrophy occurs to mark thecessation of the power of breeding and the advent of the brief oldage of our domestic animals. The advent of this period variesgreatly with species and individuals. Fertility usually persistslongest in animals regularlj^ bred and w^ell kept, while senileovarian atrophy tends to occur earliest in those animals whichare not bred and are badly kept or overworked. The disease is not to be distinguished, by palpation or macro-scopic appearances of the ovaries, from fibrous degeneration inadult animals, as alr
