must here be noticed. Let us exchange Mr. Darwin's term " correla- 

 tion of growth" for " correlation of organization," and we think we 

 attain to the means of accounting for such phenomena (as the uni- 

 formity of model in the construction of limbs in different vetebrate 

 animals) as appear to Mr. Darwin to support his theory of genealo- 

 gical affinity. Do we not find numberless instances of correlation of 

 character when it cannot have depended upon blood relationships, 

 such as associated characters of trifling importance running pai'allel 

 in genera that are most distantly separated ? Take, for instance, 

 remarkable peculiarities of colour ; as the tendency of a particular 

 shade of blue, in a number of unrelated genera of plants, to vary with 

 a peculiar and exactly uniform shade of pink flowers ; and a peculiar 

 reddish brown and yellow being associated in several unrelated 

 genera, as Calceolaria and many of the Legurainosae. 



The relationship borne by one part of an organism to another part 

 is a fact of wide application, for the works of God are all fairly and 

 beautifully proportioned ; and correlated properties (as relation in the 

 form of the head to the form of the legs) are no more unaccountable, 

 or inconsistent with special creation, than that an architect with an 

 eye to beauty should make the different parts of his several buildings 

 proportionate. If it exist in such trifling details as those just cited, 

 where correlation of growth through genealogical affinity is out of the 

 question, it is not unreasonable to suppose that the uniformity of 

 model, upon which the more important parts are formed, is the result 

 of special creation working out a consistent proportion of the integral 

 parts. 



If browns and yellows are consistent colours in unrelated genera of 

 plants, and long heads and long limbs consistent in unrelated genera 

 of animals, we may fairly carry the principle a step fiirther, and say 

 that the arrangement of bones forming a head is consistent with the 

 arrangement of bones forming a limb. So that, on the bare fact of 

 the correlation of parts, we ought to expect that the existence of a 

 leg is consistent with the existence of a head, and all gradations of 

 relation consistent, from this abstract fact down to those delicate 

 relations between the proportions of these organs which Mr. Darwin 

 notices ; and the differences in a series of heads would imply a series 

 of limbs separated by corresponding measures of difference, and 

 apparently forming a related series, though reallj', in them, individual 

 resemblances totally unconnected with each other. Again : unless all 

 organic beings had been designed without any common resemblances, 

 we must necessarily expect, on the principle of correlation of parts,
