In this and the following tables the
numbers in the body of the columns represent,

were transposed in order to eliminate any possible
space error.

General average: S,

Can anything be said, based on the reports, by way
of explanation of the advantage which complexity gives?
In the first place, the attitude of the subject towards

attitude towards an external object: to his observation
the image became, in fact, an object. “When

From time to time the images varied, too, in distinctness,
