Under the microscope, diatoms, from a prepared slide.
Each of these has been carefully isolated from a sample containing many different types, and then carefully arranged on a slide. Diatoms range is size from 0.002 - 0.5 mm so a huge amount of patience is required.
I really admire the slide maker's patience and ability.
