in that climate, have assumed the blackness of a Kaffer. The same learned prelate is of opinion that our European complexion was not primitive, but rather that of an Indian; an intermediate tint is perhaps the most agreeable to the eye and instinct of the majority of the human race. Dr. Heber, perhaps, had not seen, in various Roman catholic treasures, portraits of the Virgin Mary, painted, according to tradition, by St. Luke, and in which she is represented as a negress. That solar heat produces blackness of the integuments is an ancient opinion, and is illustrated by Pliny, who tells us, "Aethiopes vicini sideris vapore torreri, adustisque similes gigni, barba et capillo vibrato, non est dubium." Buffon asserts that "climate may be regarded as the chief cause of the different colours of man;" and Smith is of opinion "that from the pole to the equator we observe a gradation in the complexion nearly in proportion to the latitude of the country." Blumenbach, under the same impression, endeavours to account for this black tinge by a chemical illustration somewhat curious. He states that the proximate cause of the dark colour is an abundance of carbon secreted by the skin with hydrogen, precipitated and fixed by the contact of the atmospheric oxygen. Our creoles, and the British inhabitants of India, may esteem themselves particularly fortunate in not being subject to this chemical operation! On the other hand, it is well known that a black state of the skin has been produced in white races under peculiar circumstances; and Le Cat and Camper mention cases of women who turned dark during their pregnancy. It would be idle to dwell further on the hypothetic illustrations regarding this supposed operation of climate, which the observation of every unprejudiced traveller can impugn. Yet the following remarks on the subject by an American divine, the Rev. J. S. Smith are worthy of notice:
