The trick I give the mnemonic treatment to here is Jack London's "Almost Real Prediction".'
After you've given the deck a false shuffle, three spectators each take a group of four adjacent cards from anywhere in the deck. You glimpse the card above each packet taken, as in "The Three Piles" (p. 85), and mentally add the values in each group. For example, the values of Cards 8,10 and 11 of the stack (a Five, a Nine, a Deuce and a Queen) add to sixteen, since picture cards are given a value of zero, to keep things simple.
The spectators mix each group separately while you write down thegrand total, deriving it as follows: Say the total of the lir-l group is 16, the second 17 and the third 22. Write down 2 as the last digit of the result. As the preceding digit, put a 9 (7 + 2 = 9); preceding those two:digits, write a 7 (6 ,1 - 7); and as the last digit on the left pul a 1. In other words, you wnte I7V2, which , equivalent to adding the numbers in the manner to be described
Now each spectator names his cards, one by one. setting each a d. The pattern use'I to do this is: The first spectator nana, any ardteh>1*

wnle its value in a new row, under the first digit on the left. The second spectator names another card, as does the third. You write each to the right of the previous value in the second row. This process is repeated until you have four rows of three digits, arranged to be added. The addition is made and found to match vour prediction of 1792—despite the shuffles and the fact that you "didn't know" anything about the cards that were taken at random and mixed.

The pathology of the poet says that the undevout astronomer is mad the pathology of the very plain man says that the genius is mad and between these extremes, which stand for ten thousand analogous excesses, the sovereign reason takes the part of a moderator and does what it can. I do not think that there is a pathology of the occult dedications, but about their extravagances no one can question, and it is not less difficult than thankless to act as a moderator regarding them.
