. . . basic I.Q. slightly above A-type human being. Behavior . . . largely on reflex-intuition levels. The basic procedures underlying its life-cycle are not consciously comprehended by the parasite and have not, at present, been explained.


Cycle: . . . the free state, normally forming only a fraction of the Ceetal life-cycle, may be extended indefinitely until the parasite contacts a suitable host-organism. Oxygen-breathing life-forms with neural mechanisms in the general class of the human nervous system and its energy areas serve this purpose.


On contacting a host, the Ceetal undergoes changes in itself enabling it to control the basic energizing drives of the host-organism. It then develops the host's neural carriers to a constant point five times beyond the previous absolute emergency overload.


In type-case Ceetal-Homo-Lycanno S-4, 1782—a drastic localized hypertrophy of the central nerve tissue masses was observed, indicating protective measures against the overload induced in the organism.


The advantages to the parasite of developing a host-organism of such abnormal potency and efficiency in its environment are obvious, as it is indissolubly linked to its host for the major part of its long parasitic stage and cannot survive the host's death. Barring accidents or superior force, it is, however, capable of prolonging the host's biological life-span almost indefinitely.
