7. My correlations are good for me, but they may not be so vivid to others, especially where the concurrences are used. To fix the date of Magna Charta (1215), the pupil could memorise this Correlation--MAGNA CHARTA ... King John ... Jew's teeth ... DENTAL. But if the pupil did not know _before_ that King John had granted that charter, and if he did not also know the story about the extraction of the Jew's teeth to make him pay the royal exaction, there would be no concurrence as to the first word and second, or second and third, and if he learned the Correlation it would be by mere repetition without aid from Analysis. In such a case he would make and memorise his own Correlation, perhaps thus: MAGNA CHARTA ... magnify ... diminish ... DWINDLE. When a pupil makes his own Correlations, every concurrence he uses is a _real_ concurrence to him, and so with his Ins. and Exs. This is a decisive reason why the Pupil should merely look upon my Correlations as models, but make and memorise his _own_ Correlations in all cases, as being more vivid to _him_ and, therefore, more certainly remembered, as well as more effectively strengthening the Memory in both its Stages.
8. Vivid Ins. by _meaning_ are better than Ins. by S. (the latter when used, should be as perfect as possible). EAR ... EEL makes a weak In. by S. to some persons, but it would make a much more vivid first impression to most persons to deal with them in this way: EAR ... (w)ring ... twist ... wriggle ... EEL. But "Bivou_ac_ ... _aq_ueduct" is a perfect In. by S. as to the last syllable of the former and the first syllable of the latter, since those syllables are pronounced exactly alike. We may connect Bivouac to Rain thus: "_Bivouac_ ... aqueduct ... flowing water ... falling water ... RAIN."
9. _Never_--in the early stages of the study of the System--make a _second_ Correlation until you have _memorised the first_.
10. Although _making_ and _memorising_ Correlations serves the useful purpose of fixing specific facts in the memory, yet the MAIN OBJECT in making and memorising Correlations is to develop the latent power of the Natural Memory to such a degree that all facts are hereafter remembered without the aid of conscious Correlations.
