Not, one would have thought, among God's most triumphant creations, and yet--if you see them trader a microscope!--the Bot, obese, globular, obscene; the Hessian, booted, spurred, whiskered, cadaverous. Next slip under the glass an innocent grain; behold it pock-marked and livid; or take this strip of hide, and note those odious pullulating lumps--well, what does the landscape look like then?
