_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. Suppose, however, that from unfamiliarity with the Figure Alphabet, or from want of considerable practice, you do not succeed in noticing that {R}o{ck}land or He{r}{k}imer contains the number 47, you try Inclusion by Abstract and Concrete, and regarding the State of New York as the Concrete, and the Abstract or characterizing epithet "{r}o{ck}y" as applicable to New York, you would then find in that word "{r}o{ck}y" the number 47. If you did fail, you would try Exclusion, and you would find nothing which is the antithesis of the area of New York. You might find, however, a _weak form_ of Exclusion if you consider that the area is the surface, and what is below the surface as the opposite of it. In the latter case you would find in the words "E{r}ie {C}anal," which is a great artificial channel running through a part of the State, the letters "r" and "c" hard, which spell 47. A more exact Exclusion might be found in the word "{r}i{ng}," which spells 47. For if we consider the shape of the boundary of New York we would see that in no vague sense a ring, as a circle, is the opposite of it. But suppose that from a chronic absent-mindedness or an overworked brain, or downright bad physical health or insufficient knowledge of the system, you failed to see 47 in any of the foregoing cases, you would try Concurrence. Considering that the State of New York is largely agricultural, you would find that the implement of farming known as a "{R}a{k}e" would spell 47; this would be a case of Concurrence. In a political sense, the word "{r}i{ng}s" gives 47, as New York has been celebrated for them. All that the student requires is _one_ analytic word. I have gone through the varieties of Inclusion, through Exclusion, and Concurrence, merely to show _how to find_ analytic words and not because more than one word was necessary.
