This chart depicts the growth and development of the frog in a series of simple, black-and-white drawings. It illustrates only the exterior structure of the frog and shows nothing of the interior anatomy or its habitat. The sequence of drawings is also extremely clear: the chart is designed to be read in sequence from left to right, top to bottom.
