Ironically, for a man in a hurry, Howard Florey takes a very very slow plane to America

By March 1941, according to young eye witness John Hedley-Whyte , Alexander Fleming and Howard Florey both knew (via gossipy trans-Atlantic letters between eye specialists) that there had been a gratifying academic response in America to Florey's August 1940 penicillin article in LANCET.

This, after it had fallen on deaf ears throughout the rest of the world.

Much 'too gratifying' for Florey's taste (and potentially very embarrassing for Fleming).
