After Crookes: The Periodic Law

The Crookes three dimensional periodic table of 1898, here, has been adapted with the addition of two elements 'Adyarium' and 'Occultium' between hydrogen and helium, as presented to Theosophical Society (see bottom right hand corner).

Looking into this, we found the following:

INTRODUCTION TO THE THIRD EDITION By C. JINARAJADASA

This work contains a record of clairvoyant investigations into the structure of matter. The observations were carried out at intervals over a period of nearly forty years, the first in August 1895 and the last in October 1933. The two investigators, Annie Besant (1847-1933) and C. W. Leadbeater (1847-1934) were trained clairvoyants and well equipped to check and supplement each other's work.

Method of Investigation: The method is unique and difficult to explain. Many have heard of the word "clairvoyance" (clear-seeing), connoting the cognition of sights and sounds not perceived by ordinary people. In India the term Yoga is sometimes related to faculties that are beyond ordinary cognition. It is stated in Indian Yoga that one who has trained himself "can make himself infinitesimally small at will". This does not mean that he undergoes a diminution in bodily size, but only that, relatively, his conception of himself can be so minimized that objects which normally are small appear to him as large. The two investigators had been trained by their Eastern Gurus or Teachers to exercise this unique faculty of Yoga, so that when they observed a chemical atom it appeared to their vision as highly magnified.:
