Practice Preliminary is experimental philosophy, or asking discount for a bill at 18 months; Practice in General taking in the flats. The one resolves itself into "trying it on," the other to "clapping it on."
"Trying it on" is an universal principle, from the old Jew salesman who asks four pounds for a thread-bare coat and takes four shillings; or the old cabbage woman who offers 3lbs. of "taters" for two pence and sells 7lbs. for three farthings; to the prime minister who asks three millions of taxes, and expects five. The converse of this rule is, "Don't you wish you may get it."
Practice is performed by taking "aliquot parts;" to be a man of some "parts" is therefore necessary. The application of our "parts" to the science of L.S.D. with a view to their development and perfection, is the aim of the rule, and the "practice of Practice" is to show,
That the value of a thing
Is just the money it will bring;
For money being the common scale
Of things by measure, weight and rate,
In all affairs of Church and State,
And both the balance and the weight,
The only force, the only power,
