fact of _many chancres_ commonly appearing at once and _showing in a marked degree a preference for scurfy and scabby forms_, might very possibly afford a better explanation of the phænomenon in question.” Now as to the supposition just expressed, this is based on a repeated examination of a passage of the very utmost importance in the history of leprosy, viz. Ch. XIII. of Leviticus—a chapter which has exercised Theologians no less than Physicians for Centuries, but without our being enabled to regard the investigations it has given rise to as in any way concluded. However it is no intention of ours to provide in this place a commentary on this Chapter, more particularly as we do not possess the philological acquirements necessary for a critical appreciation of the results so far obtained. Neither, speaking in general terms, has anything like sufficient progress in the study of original sources for the history of leprosy as yet been made to enable an adequate judgement to be formed; we much prefer to limit our efforts at present to contributing sundry observations, which stand in close connection with our immediate object, and at the same time may afford readers, whether scientific or philological authorities, an opportunity of favouring us with their judgement as specialists. The correct understanding of the whole passage appears to us to depend in the first place on the success of the endeavour to find a certain and definite explanation of the expression בְּעוֹר בְּשָׂרוֹ (b’ôr b’sarô,—“skin of the flesh” in English Authorized Version). Luther rendered this by: _on the skin of his flesh_; the Septuagint translators give it as ἐν δέρματι χρωτὸς αὐτοῦ (in the skin of the surface); while _de Wette_ (whose Translation of the passage generally we hereby ask the reader to consult, space not allowing us to quote the whole Chapter) translates it _on the skin of his body_, and understands by the expression every part of the external skin.
