Page "Hypothetical types of biochemistry" Paragraph 30

* On the " Island Of Terror " ( 1966 ), silicon based life-forms are created accidentally by scientists while researching a cure for cancer.

The " Silicates " are not pretty, they feed on bones ( human or otherwise ) and they can reproduce by mitosis.

Not much to say about the scientific side though, since the survivors ignore how the creatures are exactly made of.

They eventually use a very 60's way to defeat them.
