penetrability

But here is another argument which proves this ready penetrability, not only in transparent bodies but also in all others.

We shall demonstrate hereafter that by this process the same penetrability may be inferred also as relating to opaque bodies.

The word penetrability is not derived from the English word penetrable, by the addition of -ty.

For this reason, the determination of the penetrability coefficient of a germicide is pertinent.

Every crime I had traced, however cleverly perpetrated, was from the point of view of penetrability a weak failure.
