How is the process brought about, or what is the physiological rationale of these phenomena? I deem it necessary to enter into some facts of embryology here, as it will be not only the single way of giving a plausible account of the facts, but also to surmise the most justifiable mode of treatment in cases where the outbreak of this disease can be feared. It is well known now that two cells in the female system concur to the formation of the embryo: the one known under the name of germinative cell, and the one described by Balbiani. These two cells have very different significations: the first one only develops itself in the adult female, whilst the second one is found to representatavic activity, as it pre-exists the other; when, however, the fecundation has taken place by the agency of Balbiani's cell upon the other, which is nothing more than a nutritive storehouse, an independent organism is formed which goes through a period of independent existence, Yery soon to vanish into an ultimate period of retrogression, unless the male spermatozoa comes to fecundate a second time the new organism and thuswise allow of the development of a new being. The male spermatozoa being organisms resulting from a like process. There is, therefore, a double fecundation. Now it becomes apparent that when the malady is inherited by those of the first generation the morbid element is entirely in the germinative cell, as it alone represents maternal influence, and as the process at that stage is a mere nutritive one, the view we must take.of the vice is that it has acted upon, first, atavic element in Balbiani's cell, and the new organism thus formed and already tainted, when impregnated by the spermatozoa, also influences that...
