$great, and the face to the small basin of the pelvis, so tliat certain lines of these two parts are always in a definite proportion to certain lines of the other. Tlius, the width of the head between the cheek bones corresponds to the upper diameter of the small pelvis; and the distance of the nose from the extremity of the chin corresponds to the length of the symphysis pubis. According to this doctrine, as the proportions of the head can easily be ascertained in the living subject, so from them those of the pelvis can be determined ; and hence likewise the exact dis- position of the uterus, and even the position of the head of the foetus.— An example is given of a man, forty-one years of age, in whom both the head and pelvis were oblique, being twisted from right to left, in con- sequence of rickets.* Turning from man to the low'er animals, we find rather more to at- tract our notice, the field being more extensive, and consequently not quite so minutely examined. Some anatomical facts have been detailed respecting the genital systems of some species, which may prove not uninteresting in a physiological point of view. On a former occasion we alluded to the discovery made by Dr. Gartner, of a glandular organ in the uterus of some of the lower animals: we are now enabled to give our readers a more circumstantial account, the author having published an essay on the subject,f detailing the progress of his investigations. He was engaged in examining the lymphatics in the uterus of a cow, when he accidentally observed a duct, or canal, filled with a yellowish fluid : this he was satisfied, from its appearance, could neither be an absorbent nor blood-vessel. Traces of it could be followed to within an inch of the ovary, and downw-ards to an opening, by which it ended, close to the orifice of the urethra. His next examination was on the uterus of a spw, three years old. Upon the side of the vagina next the bladder, he felt a hard cylindrical body, which he opened, and, finding it to be a single canal, he dissected it upwards for some inches; when, by degrees, it divided into branches, which ran into a glandular body, bearing a considerable resemblance to the pancreas. About tw'o inches further on, it again became a single canal, of very small diameter, which stretched on to the uterus. He injected quicksilver into this duct, and found that the mercury came out into the vagina by a small aperture, just beneath the opening of the urethra. He states that he has examined many uteri, both in the gravid and unimpregnated state, as well as the uteri of animals which had been deprived of the ovaries ; and that he has generally found a canal beginning on each side of the place where the vagina terminates in the horns of the uterus, running through a body of glandular structure in the middle of the vagina, under the sphincter vesicae muscle, and opening into the vagina close by the orifice of the urethra. Dr. Giirtner succeeded in injecting this canal with quicksilver. Before it is injected, it has a * Ein neuer Beitrag zur Lchre von dcr Coi\formilut dea Kopfs und Deckens,— (Nova Ada Ac;k1. Cacs. Car.
