DIAGNOSIS.--The history usually includes hypersecretion, hemorrhage, pressure, and enlargement. These, while suggestive, are not conclusive, hence physical examination becomes indispensable to accuracy. The methods of examination vary with the size of the tumor. It is generally near the truth to say that the uterus is enlarged, and may be shown to be so by the introduction of the sound; yet the cavity is not always enlarged, and it is often so tortuous that the ordinary sound may be arrested before reaching the fundus. The sound, therefore, should in such condition be flexible. The fine whalebone or the sound of Jenks will generally pass obstructions caused by tortuosities. The most skilled and dexterous use of the inflexible sound is often delusive. We may generally determine the size by bimanual examination--one finger in the vagina or rectum while the hand is passed down into the pelvis from above. The uterus of normal size cannot be felt with any distinctness from above in this way, while an enlargement of 50 per cent. may be thus determined. The finger below will sometimes recognize the pressure from above when the upper hand will not feel the fundus distinctly. Small tumors of the uterus may be mistaken for many other conditions, and the converse. If one is situated in the posterior wall, it may be mistaken for retroflexion. We may make the distinction by means of the inflexible sound and the finger in the rectum. If the case is one of retroversion, the finger in the rectum will pass behind it and overlap it above. If a retro-uterine tumor is in the cul-de-sac, the finger will not reach above the uterus. If the case is one of retroflexion, a strongly bent sound may be made to enter it, especially if the fundus is slightly raised by the finger in the rectum. If there is a tumor in the posterior wall, the sound with slight flexion will pass above it; which is clearly ascertained by the finger in the rectum. When the sound is introduced in the case of retroflexion, the fundus may be elevated to its proper position by turning the sound upon its axis. In making these examinations with the sound the finger should be made to co-operate with it by being kept in {253} the rectum. A small tumor in the anterior wall may be distinguished from anteflexion by the sound passing upward instead of forward, or into the part lying on the bladder. When a small tumor is intra-uterine, the uterus will occupy its natural position, with the mouth directed slightly backward; and if the polypus is large, the cervix can be moved forward with considerable difficulty. A flexible sound, especially the thin whalebone, may sometimes be made to partially or wholly surround it, and its size or connections be determined. But the diagnosis may be more definitely made out by dilating the cervical cavity and introducing the finger. The difference between a polypus and an intramural submucous tumor may be determined in this way. In the case of a polypus the finger will
