Combination.
CAUSATION AND EVOLUTION instance, a-b and b-a are but two permuta.. tions of a and b. Similarly Combination is their arrangement in groups without reference to the order of sequence, as for example, "a-b-c' is a combination involving a, b, and c, and 'b-a-c' is but another combination, both consisting simply of a, b, and c, grouped together In Combination, it is worthy of note, we take notice only of the presence or absence of a certain thing and pay no regard to its place in order of time and space There being buta, b, c, d and so on, it finds out only how many combinations could there possibly arise by taking at a time the two, three, or four of the symbols
While investigating into the structure Application and composition of chemical things we sub
had stitute.-H, N, O, C as symbolic represent
ation of Hydrozen, Nitrogen, Oxygen and Carbon, the ultimate rudiments or atoms of which are innumerable in number, in the places of a, b, c, d Now experiment shows that it is due to the innumerable variety of atomic combinations of H, N, O and C , that we have differences between the different
