In counting the number of ultimate atoms in a chemical
elemental atom, we did not count them throughout,
one by one; when, for instance, we counted up the
ultimate atoms in sodium, we dictated the number in
each convenient group to Mr. Jinarajadasa, and he
multiplied out the total, divided by 18, and announced
the result. Thus: sodium (*see* Plate
I) is composed of an upper part, divisible into a
globe and 12 funnels; a lower part, similarly divided;
and a connecting rod. We counted the number in
the upper part: globe—10; the number
in two or three of the funnels—each 16;
the number of funnels—12; the same for
the lower part; in the connecting rod—14.
Mr. Jinarajadasa reckoned: 10 + (16 x 12) = 202;
hence: 202 + 202 + 14 = 418: divided by
18 = 23.22 recurring. By this method we guarded
our counting from any prepossession, as it was impossible
for us to know how the various numbers would result
on addition, multiplication and division, and the
exciting moment came when we waited to see if our results
endorsed or approached any accepted weight. In
the heavier elements, such as gold, with 3546 atoms,
it would have been impossible to count each atom without
quite unnecessary waste of time, when making a preliminary
investigation. Later, it may be worth while to
count each division separately, as in some we noticed
that two groups, at first sight alike, differed by
1 or 2 atoms, and some very slight errors may, in
this way, have crept into our calculations.

In the following table is a list of the chemical elements examined; the first column gives the names, the asterisk affixed to some indicating that they have not yet been discovered by orthodox chemistry. The second column gives the number of ultimate physical atoms contained in one chemical atom of the element concerned. The third column gives the weight as compared with hydrogen, taken as 18, and this is obtained by dividing the calculated number of ultimate atoms by 18. The fourth column gives the recognized weight-number, mostly according to the latest list of atomic weights, the “International List” of 1905, given in Erdmann’s “Lehrbuch der Unorganischen Chemie.” These weights differ from those hitherto accepted, and are generally lighter than those given in earlier text-books. It is interesting to note that our counting endorses the earlier numbers, for the most part, and we must wait to see if later observations will endorse the last results of orthodox chemistry, or confirm ours.
