Dr. Panck claims that the adhesion of the orificeof the Fallopian tube with the ovary at the time ofconception, takes place through a newly-formed mem-brane, which at a later period is absorbed. He ex-amined the body of a girl who had died shortly afterconception, and found a delicate new membrane, whichfastened the fringes of the tube to the ovary. Insubsequent researches, he found a similar membraneso frequently as thirty-four times out of fifty-eightcases, but only in women who had borne 204 THE SCIENCE OF THE SEXES. CHAPTER XIII. DISPROPORTION OF THE SEXES. EMIGRATION has a remarkable influence ineffecting a disparity in the sexes—the maleslargely predominating in the new States and Terri-tories, and the reverse generally in the old settledStates. The most recent census returns show that themales of California outnumber the females nearlysixty-seven thousand, or about one-fifth of the pop-ulation. In Massachusetts the females outnumberthe males sixty-three thousand. Connecticut, seventhousand. Michigan shows nearly forty thousandexcess of males; Texas thirty-six thousand; Wis-consin, forty-three thousand. In Colorado, themales are as twenty to one female. In Utah, thenumbers are nearly equal; while in Xew Yorkthere is a small preponderance of the females; themales are most numerous in Pennsylvania. In theDistrict of Columbia, in a total popu
