To this description an English physician, who likewise saw it, adds, "It must have had two brains, as motion and sensation were equal, and apparently perfect, in each head and chest, and in all the four arms. It had two hearts, and two sets of lungs; it had also two passages into the stomach, but, as was supposed, only one set of _abdominal viscera_, as the belly was not larger than that of a common child of that age usually is. The hearts and arteries beat more strongly than was consistent with a long continuance of health. The action of the arteries was plainly seen under the skin." Mr. Buffon, in the Supplement to his Natural History, has given the figure and description of a monster something similar to this, part of which description I shall give in a note, as a parallel to that of the living child.[15] [Note 15: "In 1701 there were born in Hungary two Girls who were joined together by the loins; they lived above twenty-one years. At seven years old they were shown almost all over Europe; at nine years of age a priest purchased them, and placed them in a convent at Petersburg, where they remained till their death, which happened in 1723. An account of them was found among the papers of the surgeon who attended the convent, and was sent to the Royal Society of London in 1757. In this account we are told, that one of these twins was called _Helen_, the other _Judith_. _Helen_ grew up and was very handy, _Judith_ was smaller and a little hump-backed. They were joined together by the reins, and in order to see each other they could turn their heads only. There was one common _anus_, and of course there was only one common need of going to stool, but each had her separate urinary passage, and separate wants, which occasioned quarrels, because when the weakest was obliged to evacuate, the strongest, who sometimes would not stand still, pulled her away; they perfectly agreed in every thing else, and appeared to love each other. When they were seen in front, they did not differ apparently from other women. At six years old _Judith_ lost the use of her left side by a paralytick stroke; she never was perfectly cured, and her mind remained feeble and dull; on the contrary, _Helen_ was handsome, intelligent and even witty. They had the small-pox and the measles at the same time, but all their other sicknesses indispositions happened to each separately. _Judith_ was subject to a cough and a fever, whereas _Helen_ was generally in good health. When they had almost attained the age of twenty-two _Judith_ caught a fever, fell into a lethargy and died. Poor _Helen_ was forced to follow her fate; three minutes before the death of _Judith_ she fell into an agony, and died nearly at the same time. When they were dissected it was found, that each had her own entrails perfect, and even, that each had a separate excretory conduit, which however terminated at the same _anus_." _Linnaeus_ has likewise described this monster.
