(3) THE PUPIL MUST POSSESS SUCH A FAMILIARITY WITH THE LAWS OF IN., EX., AND CON., NOT MERELY IN THEIR THEORETIC AND ABSTRACT ASPECTS, BUT IN THAT PRACTICAL CHARACTER AND WORKING POWER OF THEM WHICH I TEACH, THAT HE CAN INSTANTLY APPLY THEM TO THE EVERY-DAY AFFAIRS AND ORDINARY OCCURRENCES AND EVENTS OF LIFE.
If you know that the number of square[E] miles in the area of the State of New York runs into _thousands_, and you wish to remember that the _exact number_ of thousands is 47, you could accomplish this object if you found a word which spells 47, and is at the same time connected by In., Ex., or Con. to New York. You try the varieties of Inclusion; and in synonymous Inclusion you find 47 in the word "Yo{ r}{ k}" itself, the "y" having no figure value, and "r" standing for 4, and "k" for 7; thus you cannot _see_ the name of New York or _think of it_ without having conclusive evidence of the number of thousands of square miles the State contains.
The title of a subject, the name or description of an event or date, can always be safely abridged or bracketed in part in the formula, as 47 [New] Yo{ r}{ k}. But no one could imagine that "York" in this connection [47 thousand square miles] means any of the towns or country seats of the United States which are called "York." If the context makes an otherwise indefinite thing definite, it is sufficient.
_Analytic date and number words do not have to be memorised._--Seeing is believing, and, in this case, _remembering_ too. If you thoroughly master my system you can find, in most cases, analytic date and number words without any difficulty, and by means of them you can remember _thousands_ of dates and sets of figures, when without the system you could have remembered only five or ten of them.
Suppose in your haste you failed to notice that "York" spells 47, and you then proceed to try Inclusion by Genus and Species; regarding York as the general word, you would find _New_ York as a species or kind of York; the same with Yorkshire, Yorktown, York Minster, etc. In this way you would, if your mastery of the Figure Alphabet were perfect, scarcely fail to notice that York spells 47; but if you fail, you then try Inclusion by Whole and Part, and run over the political divisions of the State until you come to { R}o{ ck}land County, and there you find in its first two consonants the letters "r" and "ck" (the equivalent of "k" in sound). These consonants spell 47. You would find the same consonants in the County of He{ r}{ k}imer.
