skin; there were no legs; apparently no vascular sounds; there was separate sensation, as the parasite could be pinched without attracting the perfect infant's notice. The mouth of the parasite constantly dribbled saliva, but showed no indication of receiving aliment. Louise L., known as "La dame a quatre jambes," was born in 1869, and had attached to her pelvis another rudimentary pelvis and two atrophied legs of a parasite, weighing 8 kilos. The attachment was effected by means of a pedicle 33 cm. in diameter, having a bony basis, and being fixed without a joint. The attachment almost obliterated the vulva and the perineum was displaced far backward. At the insertion of the parasite were two rudimentary mammae, one larger than the other. No genitalia were seen on the parasite and it exhibited no active movements, the joints of both limbs being ankylosed. The woman could localize sensations in the parasite except those of the feet. She had been married five years, and bore, in the space of three years, two well-formed daughters. Quite recently there was exhibited in the museums of the United States an individual bearing the name "Laloo," who was born in Oudh, India, and was the second of four children. At the time of examination he was about nineteen years of age. The upper portion of a parasite was firmly attached to the lower right side of the sternum of the individual by a bony pedicle, and lower by a fleshy pedicle, and apparently contained intestines. The anus of the parasite was imperforate; a well-developed penis was found, but no testicles; there was a luxuriant growth of hair on the pubes. The penis of the parasite was said to show signs of erection at times, and urine passed through it without the knowledge of the boy. Perspiration and elevation of temperature seemed to occur simultaneously in both. To pander to the morbid curiosity of the curious, the "Dime Museum" managers at one time shrewdly clothed the parasite in female attire, calling the two brother and sister; but there is no doubt that all the traces of sex were of the male type. An analogous case was that of "A-Ke," a Chinaman, who was exhibited in London early in the century, and of whom and his parasite anatomic models are seen in our museums. Figure 58 represents an epignathus, a peculiar type parasitic monster, in which the parasite is united to the inferior maxillary bone of the autosite.
