Uterus, ovaries, and Fallopian tubes.—May be obtained from the post-mortem room or from the lower animals. Harden in Müller’s fluid, and make sections from the cervix, the body of the uterus, the Fallopian tube, and the ovary.

Stain with eosine and hæmatoxyline.

Embryological specimens.—For systematic work special manuals should be consulted.

Specimens should be hardened in osmic acid or in Müller’s fluid, and cut in celloidin, or paraffin.

Cloudy swelling.—Specimens are obtained from organs of subjects who have died in the early stage of some fever. They should be always hardened in Müller’s fluid, as the appearances alter if the tissue is kept in spirit for any length of time.

Fatty degeneration.—Prepare from patients who have died of exhausting diseases, phosphorus poisoning, &c.

Stain in osmic acid. Mount in Farrant’s medium and keep in the dark.

Mucoid degeneration.—Study in goblet cells of normal intestine or of ovarian cysts. There are no satisfactory selective stains for mucin.
