The purer ( the more oxygenated) the blood, the greater the oxidation and warmth. The red corpuscles in a frog's blood are oval and larger than those of man. Are all of them nucleated ? (Fig. 258.) The flow of blood m the web of a frog's foot is a striking and interesting sight. It may be easily shown by wrapping a small frog in a wet cloth and laying it with one foot extended upon a glass slip on the stage of a Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bailey, L.
