is regarded as the original in- itiator into mathematics on the earth. The range of competence of this head varies from the easiest adding operations to the most difficult mathematical problems expressed by astronomical figures, including the basic ideas of the mathematical figure, of measurements and weights in relation to matter. From this head the magician may learn, for instance, how to express an idea in mathematical figures and he may, on the other side, be informed how to accumulate intellectually the knowledge of quantities and qualities. The magician is also initiated by Cheikaseph into the so- called quabbalistic quadruple key, which brings the four fun- damental mathematical operations, i. e. adding, subtracting, multiplying and dividing, into relation to quabbalistic science, to the elements of the micro- and macrocosm. Cheikaseph is a very powerful head, and the magician may learn from him more than enough.
