    The Chart of ZooLootcAL Regions, page 370, is intended to show the limits of the several Faunas of the American Continent, corresponding to the climatal regions. As the higher regions of the mountains cor- respond in temperature to the climate of higher latitudes, it will be seen that the northern temperate fauna extends, along the mountains of Mexico and Central America, much farther towards the Equator, than it does on the lower levels. In the same manner, the southern warm fauna extends northward, along the Andes. Fig. 1 Tissue of the house leek- Agassiz 2 Pith of the elder . Ibid. 3 Microscopic structure of carti- lage . . .
