The next sub-group. Ruthenium, Rhodium and Palladium, is formed on the same pattern. Fig. 142. It will be observed that each bar contains eight ovoids, instead of the six of Cobalt and Nickel. Ruthenium and Palladium have the same number of Anu in their upper ovoids, although in Ruthenium a triplet and quartet replace the septet of Palladium. In Ruthenium and Rhodium the lower ovoids are identical, though Ruthenium has the order: sixteen, fourteen, sixteen, fourteen; and Rhodium: fourteen, sixteen, fourteen, sixteen. One constantly asks oneself: What is the significance of these minute changes ?
Ruthenium — 14 (2Fel6+2Fel4+2Rul7+2Rul9)
14 bars of 132 Anu = 1848 Anu
Number weight = 102.66
Rhodium = 14 (2Fel6+2Fel4+2Rh20+2Rhl7)
14 bars of 134 Anu - 1876 Anu
Total = 1876 Anu Number weight ^^ = 10422
Palladium = 14 (2Rhl7+2Pdl5+2Pdl7+2Pdl9)
14 bars of 136 Anu = 1904 Anu

This Group fills in the gap in the periodic table. In each of the fourteen bars there are two sections, each containing three ovoids, and a cone. Fig. 143.
The lower sections in each of these elements are similar, each consisting of three ovoids of thirty Anu, X30.
X contains three groups X28 in its upper section and then a cone of fifteen Anu.
Y is similar, save that it contains only one X28 but adds two groups of twenty-nine Anu, Y29.
Z contains three groups of thirty Anu in its upper section. An isotope of Z was observed, differing only by one Anu in each bar. The cone in Z has ten Anu.
14 bars of 189 Anu = 2646 Anu
Total = 2646 Anu

The fourth group. Osmium, Iridium and Platinum is, of course, more complicated in its composition, but its builders succeed in preserving the bar form, gaining the necessary increase by additional contained spheres within the ovoids. Osmium has one peculiarity : the ovoid Os32 takes the place of the axis, in the upper half of the bar, and the three ovoids, Z31, revolve round it. In the lower half, the four ovoids. X30. revolve round the central axis. Fig. 144.
Osmium. Each section contains four ovoids very similiar to those already met with in X, Y and Z the lower four being identical with X30.
Osmium ^ 14 (4X30+3Z31+Os32)
14 bars of 245 Anu - 3430 Anu
Iridium. It will be noticed that the lower sections of the bars are identical in all the members of this sub-group, each of the four ovoids containing thirty Anu, X30. The upper ring of ovoids in Iridium and Platinum A are also identical but for the substitution, in Platinum A, of a quartet for a triplet in the second and third ovoids ; their cones are identical, containing twenty-one Anu, like those of Silver and Tin.
Iridium = 14 (4X30+2Ir26+2Ir27+Ag21)
14 bars of 247 Anu -- 3458 Anu
Number weight = 192.1
Platinum. In Platinum, we have observed two forms. Platinum A and Platinum B, the latter having two spheres of four Anu in the place of the two triplets. It may well be that what we have called Platinum B is not a variety of Platinum, but a new element, the addition of two Anu in a bar being exactly that which separates the other elements within each of the sub-groups.
Platinum A - 14 (4X30++2Ir26+ 2X28+Ag21)
14 bars of 249 Anu = 3486 Anu
Total 3486 Anu .
Platinum B = 14 (4X30+2Ir27+2X28+Ag21)
14 bars of 251 Anu = 3514 Anu
Total = 3514 Anu
Number weight - 1952
