The Stars & Stripes made fun of lice and mud, pricked the vanity of many a martinet, nurtured young journalists like Alexander Woollcott, Columnist Franklin Pierce Adams, who were later to bloom luxuriantly in Manhattan's literary gardens...
Rickettsial diseases are those associated with the presence of minute, parasitical microorganisms, believed to be transmitted largely by lice and ticks. They will be taken up at the symposium because they are sometimes associated with virus diseases, and until a few years ago there was some confusion between rickettsial conditions and those caused by virus agents...

With these they suck blood from the arms of Professor Weigl and his wife (who have already had typhus, are now immune). After a ten-day incubation period the lice are dissected. About 150 intestines are placed in a sterilized mortar with a few drops of glycerin...
