Fig. 6. Dorso-lumbar presentation; the back presenting. The fetus must be turned so that one or the other extremity can enter the passage.
PLATE XVIII. Abnormal positions of the calf in utero. Surgical instruments and sutures.
Fig. 1. Twin pregnancy, showing the normal anterior and posterior presentations. (From Fleming.)
Fig. 2. Abdominal dropsy of the fetus; normal presentation; fore limbs corded. (After Armatage.) The drawing illustrates the method of puncturing the abdomen through the chest with a long trocar and cannula. The fluid is represented escaping from the cannula after the withdrawal of the trocar.
Fig. 3. Tallich's short, bent, crotchet forceps. The forceps have bent and toothed jaws, which are intended to take hold of the fetus where neither cords nor hooks can be applied, as the ear, nose, or skin of cheek.
Fig. 4. Clamp for ear, skin, etc.: 1-1, blades with hooks and corresponding holes; 2, ring to close the blades; 3, stem with female screw for handle; 4, handle, which may be either straight or jointed and flexible.
PLATE XIX. Monstrosities. This plate illustrates various malformations and diseases of the fetus which act as the cause of difficult parturition.
Figs. 1, 2, 3. Fetuses with portions of their bodies double. Fig. 1 (from Fleming), double head, neck, and fore limbs. Fig. 2 (from Encyclop. der Gesam. Thierheilkunde, 1886), double head, neck, fore limbs, and body. Fig. 3 (from Fleming), double faced.
Fig. 4. Fetus with head very much enlarged. (From Fleming.) This affection is known as hydrocephalus, or dropsy of the brain, and is due to a more or less considerable quantity of fluid in the cranial cavity of the fetus.
Fig. 5. Skull of the calf represented in Fig. 4. The roof of the skull is absent. (From Fleming.)
