The evidence for his membership of our profession will doubtless be interesting to all physicians. Some of the distinctive passages in which Luke's familiarity with medical terms to such an extent that to express his meaning he found himself compelled to use them, will appeal at once to these, for whom such terms are part of everyday speech. The use of the word _hydropikos_, which is not to be met with anywhere else in the New Testament, nor in the non-medical Greek literature of that time, though the word is of frequent occurrence as a designation for a person suffering from dropsy (and always, as in Luke, the adjective for the substantive), in Hippocrates, Dioscorides, and Galen is a typical example. Where such vague terms as paralyzed occur Luke does not use the familiar word, but the medical term that meant stricken with paralysis, indicating not any inability to use the limbs, but such a one as was due to a stroke of apoplexy. We who, as physicians, have heard of so many cures of paralysis from our friends, the Eddyites, are prone to ask, as the first question, what sort of a paralysis it was. Luke made inquiries from men who were eye-witnesses, and then has described the scene with such details as convinced him as a physician of the reality of the miracle, and his description was meant to carry conviction to the minds of others. Occasionally St. Luke uses words which only a physician would be likely to know at all. That is to say, even a man reasonably familiar with medical terminology and medical literature would not be likely to know them unless he had been technically trained. One of these is the word _sphudron_, a word which is only medical, and is not to be found even in such large Greek lexicons of ordinary words as that of Passow. Sphudron is the anatomical term of the Graeco-Alexandrian school for the condyles of the femur. Galen and other medical authors use it, and Luke, in giving the details of the story of the lame man cured, in the third chapter of the Acts, seventh verse, selects it because it exactly expresses the meaning he wished to convey. In this story there are a number of added medical details. These are all evidently arranged so as to give the full medical significance to the miracle. For instance, the man had been _lame from birth_, literally _from the womb of his mother_. At this time he was forty years of age, an age at which the spontaneous cure of such an ailment or, indeed, any cure of it, could scarcely be expected, if, during the preceding time, there had been no improvement.
