I had come to the insight early on, through my interactions with highly gifted men, that without a serious inclination towards the knowledge of the individual, all great and general worldviews can only be an illusion. However, the details in natural knowledge are inherently capable of mutually enriching each other through a assimilative force. Descriptive botany, no longer confined to the narrow circle of defining genera and species, leads the observer, who traverses distant lands and high mountains, to the doctrine of the geographical distribution of plants across the Earth's surface according to their distance from the equator and the vertical elevation of their location. This book is an unchanged reprint of the first volume of the wonderful series on the cosmos and the description of many experiences of the great German naturalist Alexa.
