1. What is every correlation? 2. Does Analysis ever make a correlation? 3. Why would not "A" make a good In. by sound with "Anchor" on preceding page? 4. Is the method of remembering by accidental coincidences always reliable? 5. If not, why? 6. Are there cases where it cannot be used? 7. Make an original correlation between "Mitral valves" and "left." 8. How does the accidental coincidence in connection with the University crews compare with Synthesis? 9. Does this method make an impression on the novice at first? 10. Does the novice adhere to it? 11. Why? BY MEMORISING a Correlation, you so unite the two EXTREMES in memory, that you need not afterwards _recall the intermediates_. The intermediates drop out of the memory by what Prof. E. W. Scripture, Psychologist, of Yale University, calls the Law of Obliteration. 1. Why does the method fail? 2. Is it difficult to retain the steps of an argument in the natural memory? 3. Can you give any instances in your own experience where Analysis has helped you to cement Extremes together? 4. Can such a method act as a means for aiding the memory? 5. How would I manage the case spoken of? HOW TO MEMORISE A CORRELATION. To memorise a Correlation you must _at first_, if your _Natural Memory be weak_, repeat from _memory_ the intermediates forwards and backwards, as:--ANCHOR ... _sheet-anchor_ ... _sheet_ ... _bed_ ... BOLSTER--BOLSTER ... _bed_ ... _sheet_ ... _sheet-anchor_ ... ANCHOR, at least three times each way. These six repetitions from memory, three forward and three back, are only required _at first_. In a short time you will infallibly remember every Correlation _you make_; at last, the memory will become so strong, that you will no longer have to make Correlations at all. After you have repeated the Correlation, then repeat the two extremes, thus--"Anchor" ... "Bolster." "Bolster" ... "Anchor." "Bolster" ... "Anchor." "Anchor" ... "Bolster." Nothing else is so easy to memorise as a Correlation, for a Correlation is not a "mental picture" or "story"--it is neither a proposition, sentence or phrase. It has no rhetorical, grammatical, argumentative or _imaginative_ character. It is simply an elemental primordial Psychological Sequence of Ideas in which one includes another, excludes another, or in which one idea has been so often or so vividly united with another in past experience that the two are inseparably connected in memory--and a little practice in making and _memorising_ these Correlations soon makes it _impossible_ to forget them.
