undiffused

Nitrous oxyd I am still experimenting with, but its simple undiffused form is too powerful an agent to use with a patient who for many days must be hourly treated for persevering pain.

I felt the impetus of this undiffused, undissipated passion, in its undivided strength, stir and vitalise all my energies, and its power over my own frame made me involuntarily, instinctively confident of the power it would have over hers.
