With an opening likely to leave hypochondriacs in a state of blind panic, Siy and Kunkel return to introduce no fewer than nine children about to sneeze, each from a different cause, before going on to trace the reflex’s complex neuro-muscular pathways. Kunkel’s typically riveting micrographs zoom in on pollen grains, a single piece of ground pepper, a dust mite floating in a clout of skin flakes and fecal pellets, mildew, a clot of house dust, cat dander, viruses and other sneeze-inducers—all beautifully colorized (properly so noted) and carefully labeled. Capped with a gathering of extra facts, stills from Thomas Edison’s first moving picture (guess its title) and a list of resources, mostly from the web, this offering has it all—from explosive humor and drama to fascinating pictures, precise and clearly presented information, useful backmatter and a topic that touches on a universal experience.
