The pronoun _it_, according to Murray's second rule of syntax, ought to be _them_, and so it stands in his own early editions; but if _and_ be changed to _or_, as I have said it should be, the pronoun _it_ will be right.

SEVENTH DEFINITION:--"Prepositions serve to connect words with _one another_, and to show the relation _between them_."-- _Lowth, Murray, and others_.

This is only an observation, not a definition, as it ought to have been; nor does it at all distinguish the preposition from the conjunction.
It does not reach the thing in question.

Besides, it contains an actual solecism in the expression.

The word "_between_" implies but _two_ things; and the phrase "_one another_" is not applicable where there are but two.
It should be, "to connect words with _each other_, and to show the _relation between_ them;"-- or else, "to connect words with _one an other_, and to show the _relations among_ them." But the latter mode of expression would not apply to prepositions considered severally, but only to the whole class.
