The microbe is so very small You cannot make him out at all, But many sanguine people hope To see him through a microscope. His jointed tongue that lies beneath A hundred curious rows of teeth; His seven tufted tails with lots Of lovely pink and purple spots, On each of which a pattern stands, Composed of forty separate bands; His eyebrows of a tender green; All these have never yet been seen-- But Scientists, who ought to know, Assure us that is must so... Oh! let us never, never doubt What nobody is sure about! - By Hilaire Belloc from More Beasts For Worse Children. Duckworth. 1912.
