unexpected appearance of a congenital variety bearing this 
peculiar Negro character. 
10. (I.) The theory of an origin of the Isegro race by means 
of a Separate Creation is one which can only he fairly arrived 
at by negativing the possibility, or, at all events, the slightest 
probability, of any other theory. It may be contended that 
all the five or more leading varieties of mankind were created 
in distinct zoological centres of the earth, the Negro race 
having been one of these. This theory, as I have already 
remarked, at once cuts the knot of our present difficulties ; 
but still it is a theory, and one which has been solely invented 
as an escape from the apparently insoluble nature ot the 
problem now before us. This idea will not, therefore, be 
argued on any merits of its own, but simply eliminated from 
consideration by the proofs which I hope to adduce m favour 
of an origin of the Negro variety through natural processes. 
If such a view can be established, falling m as it does with 
the testimony of revelation, I think it will be quite super- 
fluous to go on further by inventing a speculative theoiy, 
which must then become both unnecessary and impertinent. 
11. (II.) The next theory may be as quickly put out ot 
view, viz., that of a Miraculous Judgment on the person op 
Canaan. For if the origin of N egro diversities be miraculous, 
of course we can dispense with any further inquiries. Ike 
bare supposition, however, is so pre-eminently gratuitous ancl 
unwarrantable, that I scarcely have patience to name it ; the 
more so, because, to those who know anything of ethnic 
genealogy, it directly contradicts the plainest facts oi the case, 
the African Negro being only a small subsection of Canaan s 
posterity, and therefore no proper representative ot this 
curse, even if it had ever fallen in this manner upon Canaan. 
Independently, however, of this, I think it will be generally 
allowed that where Holy Scripture is silent on the subject of 
miraculous agency, we have no right to invent .fresh i miracles 
for ourselves in order to get rid of scientific difficulties. fNo 
course of conduct can be more fatal to the interests of Divine 
truth • none more calculated to alienate men of science from 
theology; none more likely to increase those unfortunate 
barriers, which already too much separate philosophy and re- 
vealed religion. . . , , 
12. fill.) The next, indeed the first theory which demands 
serious discussion, is The Action oe Food and Climate, or 
other external FORCES. That in the animal kingdom sue i 
causes often operate largely in modifying size, colour, and 
even structure, admits of no doubt. 
13. With respect to Food, it is well known that hemp-seed
