The Microbe is so very small <br />You cannot make him out at all, <br />But many sanguine people hope <br />To see him through a microscope. <br />His jointed tongue that lies beneath <br />A hundred curious rows of teeth; <br />His seven tufted tails with lots <br />Of lovely pink and purple spots, <br />On each of which a pattern stands, <br />Composed of forty separate bands; <br />His eyebrows of a tender green; <br />All these have never yet been seen-- <br />But Scientists, who ought to know, <br />Assure us that they must be so.... <br />Oh! let us never, never doubt <br />What nobody is sure about!<br /><br />Hilaire Belloc<br /><br />http://www.poemhunter.com/poem/the-microbe/
