As for the pronounciation of "abiognostic," Jackie described the pronounciation that I use: "a-" rhymes with say, "biog" with a hard G, and "nostic."

"Pneumocephalic" is delightful. I am certain that I will find many occasions to use it.

Finally, I notice that in the left column under my name I am designated as a "stranger." Stranger than whom I wonder? Or perhaps it means I am a member of Merle Haggard's band... I notice that other folks are described as "addict," "old hand," "enthusiast," etc. How these designations made? Just curious.--A.W.
