Spherulitic crystals of hippuric acid, a carboxylic acid found in urine, imaged with crossed polarizers showing so-called Maltese crosses. Spherulitic structures are formed by radial crystal growth starting from a central crystal nucleus. Image recorded with a DM4 P microscope using transmitted light, 20x Plan Fluotar objective, and polarizers.
