"But you would give them the X-19 waves? They might—"
"No, of course not. But we can explain to Mitkey here how to make a very crude and limited machine for them. A primitive one which would suffice for nothing more than the specific task of converting mouse mentality from .0001 to .2, Mitkey's own level and that of the bifurcated Earthlings."
"It is possible," communicated Klarloth. "It is certain that for aeons to come they will be incapable of understanding its basic principle."
"But could they not use even a crude machine to raise their own level of intelligence?"
"You forget, Bemj, the basic limitation of the X-19 rays; that no one can possibly design a projector capable of raising any mentality to a point on the scale higher than his own. Not even we."
All this, of course, over Mitkey's head, in silent Prxlian.
More interviews, and more.
Klarloth again: "Mitkey, ve varn you of vun thing. Avoid carelessness vith electricity. Der new molecular rearranchement of your brain center—it iss unstable, und—"
Bemj: "Mitkey, are you sure your Herr Brofessor iss der most advanced of all who eggsperiment vith der rockets?"
"In cheneral, yess, Bemj. There are others who on vun specific boint, such as eggsplosives, mathematics, astrovisics, may know more, but not much more. Und for combining these knowledges, he iss ahead."
