Palladium ([Plate XVIII], 3).
In palladium this septet appears as the upper sphere in every ovoid of the upper ring.
Osmium ([Plate XVIII], 4).
We have here no new constituents; the ovoids are set free on the proto level and the contained globes on the meta, all being of familiar forms. The cigars, as usual, break free on the proto level, and leave their ovoid with only four contained spheres, which unite into two nine-atomed bodies as in silicon (see above).
Iridium ([Plate XVIII], 5.)
The twenty-one-atomed cone of silver here reappears, and its proceedings may be followed under that metal (see diagram, [p. 729], May). The remaining bodies call for no remark.
Platinum ([Plate XVIII], 6).
Again the silver cone is with us. The remaining bodies are set free on the proto level, and their contained spheres on the meta.
Lithium ([Plate IV], 2, and [XIX], 1).
