scattered through the whole cytoplasm together with smaller cells with
exceptionally large hyperchromatic nuclei. Subepithelial tissue is
especially congested and contains numerous fibroblasts together with a
few well formed glandular acini. Lining epithelium is discontinuous,
of simple tall columnar type, in places becoming flattened or even
lost. Lumen of organ is practically completely occupied by pus.
The Indian Elephant “Empress” (_Elephas indicus_) showed calcified
fibroids of the fimbriæ; gross and microscopic notes and a photograph
are given. The uterus is bicornate in type. In its body there are
numerous fibrous nodules 1 to 4 cm. diameter. They can be traced from
the cervix to the ends of both horns and tubes. At the end of each
tube there is a great mass of calcified partly conglomerate tumors
some of which are partly, others quite, pedunculated. One specimen
measuring 2 × 1 × 1½ cm. has a peduncle 15 cm. long. The mass on the
right side weighs 3,926 grams, that on the left side about the same.
Section of tumor from uterine cornu shows the classical appearance of
a leiomyoma with usual whorling and interlacing bundles of involuntary
muscle fibres. Degenerative and vascular changes not seen nor is there
any notable addition of fibrous tissue. This latter tissue is shown
only in small amounts at one end of section.
The preceding data record the discovery of three fibromata of the uterus
and one of the fimbriæ; one fibroadenomata of the cystic type, one
malignant adenoma, one adenocarcinoma, and one chorionepithelioma. They
were found in Lemures 1, Carnivora 2, Ungulata 2, Proboscidea 1,
Rodentia 1, and Edentata 1. Metastases occurred but once, to the lung.
No secondary tumors were found in the uterus.
While upon the subject of neoplasms of the female genitalia, it may be
well to describe the three instances found in the avian organs. A very
definite case of adenocarcinoma occurred in the oviduct of an Undulated
Grass Parrakeet (_Melopsittacus undulatus_), a variety of bird very
susceptible to neoplasms. The notes in an abbreviated form are given:
