Rapport sur les travaux de la mission scientifique du Katanga : (Octobre 1910 à Septembre 1912)
The Harvard African Expedition of 1926-1927 was planned for the purpose of making a biological and medical survey of Liberia, which apparently was that country of Africa about which the least was known in those respects. It was also planned, after the survey was completed, to cross the continent of Africa from the west to the east coast, travelling particularly through the Belgian Congo, and to make comparative studies in these regions. This program was carried out. This publication is the result of this expedition.

After nearly fifty years since his first journey to the tropics exploring for plants, and a total of thirty-nine expeditions to the Amazon, Professor Sir Ghillean Prance has gathered in this volume a fascinating and diverse collection of accounts from these experiences, along with his thoughts on a lifetime of work surveying the Amazon flora.
Au premier printemps du millénaire, Frederik Paulsena foulé le pôle Nord et découvert que la Terre cachait d’autres pôles : le pôle magnétique, ce point mouvant que désignent les boussoles, le pôle géomagnétique, plus stable, et le pôle d’inaccessibilité. Comme la terre a deux hémisphères, ces quatre « pôles Nord » ont leur jumeau au sud, en Antarctique. Frederik Paulsen s’est lancé un défi : devenir le premier homme à atteindre les huit pôles de la planète.
