ABSTRACT
The methods hitherto described relied mainly on the fact of conjunction and its constant repetition. But already in the highest development of these methods we were forced to pay some attention, on the one hand, to the character of the conjunction itself, so far at least as its definiteness or precision were concerned; and on the other, to its surroundings, so far as these are indicated by the extent of space and time pressed into our service. The methods which follow are distinguished by relying entirely on the character of the conjunction together with its concomitants in different cases.
